For my fanfiction rewrite of Sonic and the Black Knight, here's Mighty the Armadillo as Sir Gaheris, a Knight of the Round Table. I named him Gaheris because Gaheris, along with Gareth and Agravain were Gawain's brothers in the original Arthurian myth and Knuckles, Mighty, Espio and Vector are all members of the Chaotix.
Like with Espio as Sir Gareth, I mainly armor-fied Mighty's normal look. I added the spikes because I wanted to do that on someone and emphasize that he is a physical fighter. His visor slides up and he doesn't have armor on his shell.
Sir Gaheris is a noble knight of the Round Table. Born into poverty, Gaheris was gifted with incredible physical strength, which only served to isolate from other children. Seeing the potential in Gaheris' might (haha), King Arthur took the young boy in and he was trained as a knight. He is immensely protective of his allies as well as anyone he sees as innocent and weaker and is quick to shield them from harm. This can easily be traced back to the guilt he feels from failing to find his parents and lost younger sister. As such, he is quite protective of his squire Rivalen (Ray the Flying Squirrel). Despite his isolated childhood, he remains quite optimistic and rather sensitive to other people's feelings. He tries to see the good in everything and is not one to hold grudges. As the physically strongest knight, Gaheris wields no weapons, instead he uses his fists. His armor is much stronger than the other knights, which is needed when Gaheris uses him incredible strength, and he can roll into a ball to shield himself.
