Potcha

and his partner Mondai were two imposters who tried infiltrating Konohagakure.

Background
Potcha and Mondai sought fame in their village and apparently spent months perfecting their "disguise" technique.

Personality
Potcha appears to be goofy and not very smart, very much like his partner Mondai.

Abilities
Potcha along with Mondai put on football helmets and charge at the enemy with a high-speed attack though it is unknown what the effects of this technique are since it was halted.

The Appearance of Strange Visitors
Potcha and Mondai went to infiltrate Konoha and gather its secrets by disguising themselves as Rock Lee and Might Guy respectively, while the real Guy and Lee are out on a mission. They are oblivious to the fact that their disguises are fooling nobody, except for Naruto, Tsunade, Sakura, and Tenten force them along by giving them outrageous missions, preventing them from learning anything. They are defeated when the real Guy and Lee attack them with their Double Dynamic Entry technique.

Trivia

 * Potcha calls himself while disguised as Rock Lee, which is a pun for, meaning "chubby".
