Mecha-Louie

Mecha-Louie is a massive robot that serves as a secret final boss of Pikmin 5: Adventure Awaits. It possesses the likeness of Louie, who it is named after and controlled by. On its left forearm is a cannon which Louie uses to fire lasers at leaders and Pikmin. Louie is also able to make his mech detach its hands and crush his attackers. Louie is able to fire from a launcher on its back missiles that fall downwards from above and explode upon contact with anything in their path. The music that plays during the fight against Mecha-Louie is none other than "Brainiac Maniac" from Plants vs. Zombies, which, in that game, plays during a battle much like the one against Mecha-Louie.
