The Titan Dweevil is the final boss in Pikmin 2. It is the largest member of the Dweevil family, and arguably one of the largest creatures in the game. Unlike other dweevils, its only natural attack is to lash out with its pincers, which does no damage and is only an attempt to get Pikmin off it; the creature is only really dangerous because of the weapons it carries.

At the very bottom of the last dungeon in the game, the Dream Den, Olimar and The President find Louie sitting atop a mound of treasure. When they approach the mound, however, it reveals itself as the head of the Titan Dweevil. The enormous monster then proceeds to attack the player, triggering the boss fight. Louie is found on top of it the first time you battle it; the Sales Pitch on him as a treasure suggests that he may somehow be in control of the Dweevil (although if you go back in the dungeon and fight the boss after rescuing Louie, it will still attack you if you didn't take the weapons last time).
