Nagagog

A Nagagog is a sumo wrestler-like enemy with a decorative twirl on its head and a small mouth. It is encountered in The Subspace Emissary in Super Smash Bros. Brawl. It will start small and blue, but if it takes enough damage, it makes a laughing noise and grows larger, also turning yellow in the process. As it takes more damage, it will turn into an even larger version of itself with a red color.

While the Nagagog is changing into a larger version of itself, it will not take any damages from attacks or items. Its health decreases much faster when it is in its larger forms. It attacks like a wrestler, jumping on top of the player. Its attack is a body slam that damages players in proportion to its body size. If players are quick with attacks, however, they may be defeated before they have a chance to reach full size.

There is a trophy of Nagagog, which shows it in all three sizes.
