Scornet Maestro
This boss is the fourth boss encountered in Pikmin 3. It commands the Bee-like enemies to attack your Pikmin. It quickly abducts Louie before the player can reach him. The appearance of it is extremely similar to the Hachisuzume (the bee-like enemies)
and it commands them to attack your Pikmin swarm using its harp-like beak. It cannot be attacked while its own swarm is surrounding it, requiring the captains to aim their Pikmin (preferably Winged Pikmin) at the boss after it exposes itself after one of its coordinated attacks.
Strategy
The strategy is mainly to defend your Pikmin from the bees and then attack the boss. As the battle progresses, the boss will create different formations with its bee-like workers in an attempt to destroy your swarm. One should note that this boss completely relies on its own swarm to attack, possessing no offensive moves of its own besides shaking off Pikmin. The first formation is a gigantic cone-like formation, the easiest to avoid. The attack is simple to dodge, just wait for the formation to being attack and strafe around the swarm. If any Pikmin are caputured by the swarm, the swarm will move the around the boss in a circle formation, holding your captured Pikmin. The swarm must be attacked swiftly to free the Pikmin, if Pikmin aren't released from the swarm,
they will be killed. The second formation is shaped like two paralle lines. The third formation shows the swarm forming a circle surrounding you, slowly closing in, you need to use your Pikmin to create gaps in the circle to allow your group to escape. Once any of the formations are complete, the swarm will temporarily leave the boss, giving you a chance to attack the boss, which you can use Winged Pikmin to reach it, once enough Pikmin are latched onto it, it will fall to the ground, allowing any ground-based Pikmin to swarm it as well. Once it dies, it will expell a big fruit, alongside Louie. Its body, alongside the corpses of its swarm, can be taken back to the Onion.
