Nagagog

The Nagagog are a group of enemies in the 2008 videogame Super Smash Bros Brawl. They are part of the Subspace Army and work for Tabuu, who is the main antagonist of the game. Their appearance is somewhat of that a sumo-wrestler. They start off small but as they fight one of the main characters, they change colors from blue to yellow to red growing to a very large size.

Personality
Nagagog seem to have a calm demeanor until they are attacked or detect an enemy. When they take enough damage they let out a laughing noise and change to their giant size. This could suggest that they enjoy fighting opponents they come across.
