Gus

Gus is an enemy found during the events of Paper Mario: The Thousand-Year Door. He is first seen during the Prologue of the game, in which Mario and Goombella can talk to him. Gus is found outside of Professor Frankly's office, guarding the passageway to the far east area of Rogueport. If Mario or his partner walk up to him, he will request a toll of ten coins for them to pass by, though the next time they pass through, they must again pay ten coins. Mario is also given the option to fight Gus, in which once Gus is defeated, Mario never has to pay a toll to pass into the far eastern portion of Rogueport.

Gus is also notable for being a member of the Robbo Gang, and the only one of them that the player can battle. Gus can later be found in Ishnail's hideout, guarding Ishnail himself, along with another Craw &mdash; Garf. Gus can only be battled once, but unlike all other enemies that can be battled only once, he is not a semi-boss.

In battle, Gus attacks using his sharp spear. Gus will either charge towards Mario or his partner, ramming into them with his spear, or he will hurdle a spear at the player, inflicting the same amount of damage. Mario cannot jump on top of Gus because of his spear; instead, he must attack Gus with his hammer. In the same manner, Goombella cannot Headbonk Gus. Rather, the only attack she can perform on Gus is Tattle because she makes no direct contact with Gus. However, Koops can attack Gus, because he attacks enemies from the side while hiding in his shell. Bobbery, Vivian, and Ms. Mowz can also attack Gus, because they attack from the side as well. However, this is only if Gus is still able for battle when the player acquires them as partners.
