Oatchi (オッチン^?) is a Rescue Pup, a type of space dog that is part of the Rescue Corps. In-game, he is the companion of the player's character, assisting them with transportation, by working like a Pikmin, by performing specialized tasks, and by serving as a secondary leader if the two are separated. His breed of space dogs has long served the Shepherd family, and he obeyed only Erma Shepherd, the captain of the Rescue Corps, until the player's character appeared. Like his owner, he is from the planet Giya.

Gameplay

Squad member

Normally, Oatchi is a part of the player's squad, just like a Pikmin. In the same way the player can throw or charge a Pikmin towards a task, they can point Oatchi to one. Like a Pikmin or leader, Oatchi can become idle, and he will do some nearby tasks on his own, like taking down Pellet Posies, but won't do others like carrying. When idling, his tail will glow like an idle Pikmin's leaf, bud, or flower.

Solo

If the player's character and Oatchi get separated, be it incidentally, by dismissing, or by choosing to switch control between the two, Oatchi will be able to act independently, and even be controlled like one would control a leader.

While separated, Oatchi is able to walk around the area freely like a leader, and even jump. These actions can both be done by the player while controlling him, or be done automatically with Go Here! When Pikmin are in Oatchi's squad, they jump on his hips. Because they're all close together, this has the benefit of not having the squad of Pikmin spread out on the floor, meaning it is harder for enemy attacks to hit or for Pikmin to fall behind, especially on thin pathways with no guard rails from falling below. During manual control, he can whistle and throw Pikmin or items, the former being done by what is called "bark" in-game, and the latter being done by Oatchi biting the thing in question and flinging it. He can also continue to perform tasks as if he was still a squad member. He cannot charge Pikmin, as this function is replaced by his Rush ability.

If the player's character whistles Oatchi in this state, he will return to being a part of the squad. If Oatchi whistles the leader instead, they will hop on Oatchi's back to ride them.

Riding

When Oatchi is nearby, the player's character and their Pikmin can ride on his back and hips. Like with controlling Oatchi solo, this helps avoid stray Pikmin casualties. While riding Oatchi, the player takes control of both him and the player character at once, and different gameplay mechanics work as if the player was controlling a specific one:

Throwing and whistling is done by the riding leader.
Walking around is done by Oatchi, as is jumping, rushing, swimming, and biting, and Oatchi takes damage when the player is attacked (though the player character can be thrown off). The player can transport objects as if they were controlling Oatchi solo.

Vulnerability

Oatchi is a character alongside the player's character. Both of them have their independent health, and can be knocked down if that health reaches zero. If Oatchi comes into contact with a hazard, he will be affected in a similar way to Pikmin if he is not currently immune to them. For instance, if Oatchi gets hurt by fire, he'll run around in a panic with his tail ablaze and his HP dropping, and the player's character will have to whistle him in order to extinguish him.

Some of the gear available at the lab can be applied to Oatchi as well, though they must be bought with raw material separately from the leader's version of the upgrade. Oatchi's version costs more raw materials to purchase than the leader's equivalent.

Training

Training is unlocked after Oatchi grows up, which happens once Russ is saved. By talking to Shepherd in the Rescue Command Post as the player character, it is possible train Oatchi in order to unlock new skills or level up existing ones. This can only be done if Oatchi has enough drive to learn new tricks, indicated in-game by a point system called Pup Drive. Each skill costs a different amount of Pup Drive. Pup Drive is increased by 1 for every rescued castaway, and another for every cured leafling.

In the training menu, the player can see how much Pup Drive is available, a list of available and known skills, and the current level of each. They are also capable of learning more about what each level does.

Five of Oatchi's skills are already a part of Oatchi's skillset from the get go: buff, chomp, rush, dig, and command. Some others are learned automatically through story progression instead of being taught by Shepherd with with Pup Drive.

Skills

Buff

Oatchi is capable of carrying objects by biting them and dragging them, either solo or alongside Pikmin. In addition, Oatchi can also push obstacles like paper bags. He can do these things when ordered like a Pikmin, or if being controlled by the player, when the player approaches the task and presses . He will keep working until the player, as Oatchi, cancels with , or when whistled. Without Rush Boots, Oatchi carries objects at the same speed as an average leaf Pikmin.

Leveling up Buff increases Oatchi's strength, allowing him to lift heavier objects. Each level of Buff costs one Pup Drive.

Buff level 1: Strength of 3 Pikmin. Oatchi starts at this level for free.
Buff level 2: Strength of 5 Pikmin.
Buff level 3: Strength of 10 Pikmin.

Super Buff

Super Buff is a skill that becomes available after Buff has reached level 3. Each level of Super Buff costs two Pup Drive.

Super Buff level 1: Strength of 20 Pikmin.
Super Buff level 2: Strength of 30 Pikmin.
Super Buff level 3: Strength of 100 Pikmin.

Swallow

Warning: the following text contains major spoilers about Pikmin 4 's postgame.

Swallow allows Oatchi to eat an object, bring it somewhere, and then spit it back out. While Oatchi is capable of doing this with small things like raw materials from the get-go, the skill allows him to swallow bigger objects. Oatchi's movement speed is unchanged regardless of the object he has swallowed. Additionally, Oatchi will not swallow objects that are being carried by Pikmin, apart from objects being carried exclusively by enemy Pikmin in Dandori Battles. This skill is taught by Olimar after rescuing him and learning Super Buff level 3. It costs no Pup Drive and only has one level.

Chomp

When commanded by the player's character, Oatchi will run at an enemy and attack them by biting. When controlling him (and without having Pikmin), chomp can be used with like how one would punch with a leader. If Oatchi is idling near a target or is attacked by an enemy, he will automatically use chomp whether he is commanded to or not.

Leveling up Chomp increases Oatchi's attack damage. Each level of Chomp costs two Pup Drive.

Chomp level 1: Chomp deals 35 damage (compared to a Blue Pikmin's 10 damage). Oatchi starts at this level for free.
Chomp level 2: Chomp deals 55 damage.
Chomp level 3: Chomp deals 75 damage.

Big Chomp

Big Chomp is a skill that becomes available after Chomp has reached level 3. Learning Big Chomp allows Oatchi to bite in midair, either automatically, or by pressing after a jump. Each level of Big Chomp costs three Pup Drive.

Big Chomp level 1: Chomp deals 90 damage.
Big Chomp level 2: Chomp deals 105 damage.
Big Chomp level 3: Chomp deals 120 damage.

Rush

Oatchi can charge at enemies or obstacles. For example, he can smash open jars and frozen objects, or ram into walls to knock down hard-to-reach items. It can also provide enough speed to run against the direction of conveyor belts or instantly burst any frozen hydro jellies. When Pikmin are riding Oatchi, he can also launch the Pikmin directly onto an enemy or obstacle when rushing into them.

It can be performed by holding and releasing , be it by being ordered by the player's character or when the player is controlling Oatchi directly. While the button is pressed, an orange ring-shaped gauge appears with Oatchi's face on it and fills as the button is held down. An arrow also appears on the ground indicating where Oatchi will go. If the button is released after the gauge is full, the rush will start, but if released before that the process will be canceled. Before releasing the button, the player may press another button to cancel. While rushing, if the player controls Oatchi, he can be slightly veered left and right. Oatchi can usually only rush for a few seconds before screeching to a halt on his own, or sooner if the player presses mid-rush. After rushing, the same gauge will appear with a grey ring instead, slowly depleting to indicate the cooldown between Oatchi's rushes.

When rushing against an enemy, the result depends on how powerful the rush skill is and how tough the enemy is. Oatchi will run straight through lighter enemies like the Dwarf Bulborb or Water Dumple. Medium-sized enemies like the Firey Blowhog will be knocked slightly in the air. Meanwhile, heavier enemies and bosses will be unmoved. Lighter enemies also take much more damage compared to heavier enemies.

Oatchi's slam will knock down nearby objects in tall ledges in a fixed radius around him, meaning the player does not need to hit the wall that a thing is on in order to knock it down specifically. This radius will also automatically pluck any nearby sprouts, regardless of what he slams against.

Leveling up Rush grants different effects, either reducing charge time or increasing damage. Each level of Rush costs three Pup Drive. Damage values for Rush were measured against the Firey Blowhog, but share similar results with other creatures.

Rush level 1: Oatchi charges his rush in 2 seconds. He has a five-second cooldown after Rush is finished. Oatchi starts at this level for free.
Rush level 2: Charge time decreases to 1.6 seconds.
Rush level 3: Rush deals about 20% more damage.

Mega Rush

Mega Rush is a skill that becomes available after Rush has reached level 3. Learning Mega Rush allows Oatchi to stun larger creatures on impact. Stun time is variable, similar to damage. Each Level of Mega Rush costs four Pup Drive.

Mega Rush level 1: Charge time decreases to 1.4 seconds.
Mega Rush level 2: Rush deals an additional 20% (now 40%) more damage.
Mega Rush level 3: Rush's stun lasts almost twice as long, and its charge time is decreased to 1.3 seconds.

Jump

By pressing , Oatchi will perform a small jump. This is required in order to get up some small ledges that the player's character and their Pikmin cannot go over alone. This skill is unlocked automatically the day after Russ is rescued, costs no Pup Drive, and only has one level.

Dig

When sending Oatchi with , he can excavate objects like the Pikmin, such as buried treasure, cave entrances, or dirt mounds. He can also do this if the player is controlling him solo, approaches the task, and presses , after which he can be stopped manually by pressing .

Leveling up Dig increases Oatchi's Digging Speed. Each level of Dig costs one Pup Drive. Measurements for digging speeds are approximate.

Dig level 1: Oatchi digs at 16X speed. Oatchi starts at this level for free.
Dig level 2: Oatchi digs at 28X speed.
Dig level 3: Oatchi digs at 52X speed.

Doggy-Paddle

Oatchi can swim in the water. While swimming, his back and hips are above the water, allowing the player's character or any Pikmin riding him to continue doing so as he crosses a body of water. When Oatchi is first led into the water, a cutscene will play showing him failing to swim. He will gain this skill two in-game days after the botched attempt as long as he is grown up (and after selecting an area, thus it cannot be upgraded until the next day). If two days pass before he grows up, he will learn the skill the day he grows.

Leveling Up Doggy-Paddle increases Oatchi's performance in the water. Each level of Doggy-Paddle costs two Pup Drive. Swim speed is also affected by the Rush Boots.

Doggy-Paddle level 1: Oatchi swims with a 33% movement speed penalty. Oatchi learns this level automatically, costing no Pup Drive.
Doggy-Paddle level 2: Oatchi swims with a 16.5% movement speed penalty.
Doggy-Paddle level 3: Oatchi gains the ability to dive, allowing him to attack underwater enemies and obstacles, as well as carry objects underwater.

Pluck

Pluck allows Oatchi to pluck Pikmin sprouts. Further levels increase the speed at which he can pluck. Each level of Pluck costs one Pup Drive. Measurements for plucking speeds are approximate. The number in parentheses is when Oatchi plucks multiple Pikmin in a row.

Pluck level 1: Oatchi is able to pluck Pikmin sprouts every 0.75 (0.3) seconds. This is the same speed as the captain.
Pluck level 2: Oatchi plucks Pikmin sprouts every 0.7 (0.25) seconds.
Pluck level 3: Oatchi plucks Pikmin sprouts every 0.6 (0.2) seconds.

Heal

Heal is a skill that allows Oatchi to automatically regain his health over time. Each level of Heal costs three Pup Drive. We are unsure about the exact numbers.

Heal level 1: Oatchi is able to heal himself over time.
Heal level 2: Oatchi heals faster than before.
Heal level 3: Oatchi heals even faster than before.

Commands

Commands are a set of tasks the player can give to Oatchi, accessible with , or with a mapped shortcut. Each level of Commands costs three Pup Drive.

Command level 1: Oatchi can pick up scents, specifically for castaways and treasures. When Oatchi picks up a scent, blue smoke particles appear allowing the player to visually follow the path. If not controlling Oatchi, he will follow it automatically to its source. Oatchi starts at this level for free.
- Pick Up a Scent: Oatchi sniffs out for any important thing, typically one that is important for story progression.
  - Castaways: Oatchi will locate any castaways nearby.
  - Treasure: Oatchi will locate any treasure nearby.
  - Onions: Oatchi will locate any Onions or Flarlic.
  - Raw Materials: Oatchi will find any raw materials nearby.
  - (Type) Pikmin: Oatchi will locate Pikmin of a certain type without an Onion and bring them to the player's character.

Command level 2: Oatchi learns 'Come Here' and 'Go to Base'. This also enables Go Here! for him and the player character.
- Come Here: If separated from Oatchi, the player can call him to their current location.
  - When separated, Oatchi can use this command to have the player character do the same.
- Go to Base: Oatchi will head to the current base.
  - When separated, Oatchi can use this command to have the player character do the same.

Command level 3: Oatchi learns 'Gather Pikmin'
- Gather Pikmin: Oatchi will find any stray Pikmin not performing tasks and bring them to the player's character.
  - When separated, Oatchi can use this command to have the player character do the same.

Infinite Rush

Once Oatchi has been taught every skill by Shepherd, as well as the additional skill by Olimar, he is capable of learning one final "Legendary Skill"; the Infinite Rush. This costs eight Pup Drive, and as the name suggests, allows Oatchi to run during his rush for as long as desired; stopped only by hitting a wall or pressing . It only has one level.

Personality and appearance

This section is a stub. You can help Pikipedia by expanding it.
Suggestions: Describe his personality.

Oatchi has golden fur, with orange spots on his back, a thin tail that usually ends in a white tuft, two legs in total, two floppy ears, a collar, blue eyes, and no nose (although he smells every scent). Despite his alien look, he barks like a real dog. After curing Bernard, his tail will turn into a leaf. This is reverted upon obtaining the Gift of Friendship.

Naming

Oatchi's English name is derived from his Japanese name. His English name is phonetically similar to Yoshi. This is likely an intentional reference, as Oatchi is ridden much like Yoshi and follows similar naming conventions with Olimar, whose name is derived from Mario, as Louie is from Luigi.

Trivia

Oatchi will squint his eyes if he is near an enemy. Moss will also do this in Olimar's Shipwreck Tale.
- Strangely, Oatchi will do the same thing if near the Gildemander and Gildemandwee's fake golds, suggesting it is counted as a enemy.
