Mighty The Armadillo
Mighty the Armadillo is a character in the Sonic the Hedgehog universe.Mighty is an explorer and a long time acquaintance of Sonic the Hedgehog.
Mighty's first appearance was in the arcade game SegaSonic the Hedgehog, where he was captured by Doctor Eggman along with Sonic the Hedgehog and Ray the Flying Squirrel. They were taken to Eggman Island and imprisoned, but they made their way through the island's defenses and escaped, destroying the island in the process.
In this game, Mighty played exactly like Sonic and Ray; he was fairly fast and could roll into a ball to perform the Spin Attack and Spin Jump.
Mighty reappeared in Knuckles' Chaotix for the Sega 32X. In the Japanese manual, he just happened to stumble across the island which the adventure is set on during his explorations. In the American manual, he is a friend of Knuckles the Echidna, and happens to visit "Carnival Island" when Eggman attacks.
In both manuals he is captured by Eggman, and imprisoned in his "Combi-Confiner" machine. When Knuckles arrives, he can pick Mighty out of the machine and use him as a partner. Mighty plays very much like Sonic from the previous Sonic games, using his Spin Attack and Spin Dash. He also has the ability to kick off walls in order to gain height.
In the games, Mighty is a gentle and caring pacifist, only using his strength and fighting abilities when there is no other option. He loves to travel, and his dream is to journey to all places of the world. According to the Japanese booklet of Chaotix, Mighty enjoys forest bathing, likes peace and nature, and detests violence.
Like most characters in the Sonic 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's unique move in Chaotix was a wall kick that let him kick off a wall, gaining some height and letting him traverse up shafts as long as the walls are close enough to each other. Despite his namesake, Mighty has never demonstrated a single feat of super strength in the games continuity and it is never directly stated in any official literature related to Chaotix or SegaSonic Arcade that he has such an ability.
