Mighty the Armadillo

Mighty the Armadillo is an anthropomorphic armadillo and one of the protagonists with a giant red thick armor on his back. He is a strong fighter who isn't always serious, which is mostly shown alongside his best buddy Ray the Flying Squirrel. He helps fight off Dr. Robotnik and Metal Sonic and their evil deeds.

Mighty and Ray
When Ray looks for Mighty, he gets attacked by Metal Sonic, Metal is threatening him for a Chaos Emerald. Just as Metal tries to hurt him, Mighty blocks his blow with his shield on his back. Mighty picks up a rock and smashes it in Metal Sonic's robotic cheek. When he lands, he throws the same rock at him. Ray hugs him and gives a friendly punch on the shoulder to him. Mighty does so back, but a little harder than usual. After picking him up, Metal charges at Ray and chokes him, he demands the chaos emerald Mighty has. He has no use but to give it to the robot. Metal throws Ray away and rises upwards. Mighty throws a final rock at him, but Metal already flies to Robotnik's Lab. Ray suggests that Mighty should throw him upwards as well. Ray then tells him where Metal is charging at and Mighty follows Ray's lead.

Metal Mayhem
Sonic the Hedgehog already began their battle and they get pinned onto a wall. Next to that very wall, Ray and Mighty walk in. Mighty looks furiously at Metal Sonic, who is now superpowered. He punches Metal Sonic and everyone gets ready to fight the superpowered replica of Sonic. Metal Sonic receives a heavy punch from Mighty, but Mighty can still block a rough kick from Metal back.

After Tails and Sonic return the Chaos Emeralds, Metal Sonic stands on top of the Master Emerald, gaining power once again. But suddenly, Knuckles fiercely punches Metal into Robotnik for stealing the Master Emerald. After Knuckles normally brings the Master Emerald back in it's place, Mighty goes along with Sonic, Tails and Ray for a nice lunch of Chilidogs.

Appearance
Mighty is a black armadillo with a thick red shield he carries on his back. He has a very pointy nose, a small black tail and two white gloves. He also has a peach-colored muzzle, belly, arms and funnel-shaped ears. He wears bright red shoes with white straps, but they don't reach the soles.

Trivia

 * Mighty's shoes are identical to Sonic's, except the fact that the straps are not connected to the soles.
