Mighty the Armadillo

Mighty is one of the few characters on Sonic the Hedgehog series. He makes his first appearance in the arcade game SegaSonic the Hedgehog along with Ray the Flying Squirrel. He was absent after the rest of the group, especially the ChaotIx was reintroduced of the series Sonic Heroes. It stated that Mighty will make his return on Sonic Ultra Rush with his best friend Ray and Honey the Cat.

Powers and Abilities
Like most characters in the series, Mighty has some super speed. Mighty can use the Spin Attack, where Mighty curls up into a compact ball and rolls into enemies. He also has the Spin Jump, during which Mighty jumps into the air as a ball. Mighty has the Spin Dash (originally named the "Super Spin Dash") as well, which allows him to charge up a Spin Attack from a standing position, and then shoot off towards enemies. Mighty also has incredible strength, able to easily rip apart metallic objects and can lift incredible masses with relative ease. Mighty's powers can fluctuate depending on his health and emotions; when enraged, he's especially destructive. However, his strength apparently has its limits.

Personality
Unlike his previous past, Mighty is more heroic individual who wants to help everyone he can, not unlike Sonic. However, Mighty's great strength is a source of some paranoia, as he is afraid of losing control and hurting someone. This provides him with something of a temper, which grows more prevalent when he feels helpless. Like Sonic, he tends to take more upon himself than is sensible, though he also appears to possess a high sense of decorum.

Mighty is very protective of his allies, often quick to shield them or ensure they're uninjured. He is extremely protective of Ray the flying squirrel, whom he regards as his adoptive younger brother. He is also not particularity aggressive, though he enjoys physical activity and is willing to fight for a good cause, especially for the safety of the weak or small. He was shown to be good with others and is somewhat sensitive of hurting their feelings; indeed, he has a very kind heart.
