Metal Slug is a run and gun video game series created by SNK. It focuses on the adventures of Peregrine Falcon Squad, a crack team of commandos who battle aliens, dictators, and other factions bent on world domination.
Fitting in with the series' cartoony bent, eating 16 pieces of food causes your character to spontaneously gain weight. Power is increased while speed is greatly lowered, and humorous changes are made to the character's animations, including using a fork instead of a knife as a melee weapon. The transformation wears off eventually on its own, but can be cured quicker with a diet pill or barrel of diet formula.
