Espio the Chameleon as Sir Gareth, Knight of the Round Table.
In my fanfiction rewrite of Sonic and the Black Knight, I thought to myself, why limit it to just the 5 (3 for the story) knights they used when there are more characters that would make great knights?
So here's Espio as Sir Gareth. I chose for him to represent Sir Gareth because Gareth is one of the brothers of Gawain (Knuckles). Since together Knuckles, Espio, Mighty and Vector are members of the Chaotix, I felt it was more fitting than any other name, with Mighty being Gaheris and Vector being Agravain, Gawain's other brothers.
For Gareth's design, I pretty much armor-fied Espio's normal look, like they did with the other characters. The design of his helm is based on a ninja shuriken and the armor over his horn lifts up with his visor. The symbol on the helm is the symbol of the Shinobi Clan, the ninja clan of chameleons that Espio serves in the mainstream comic books. He does not have a main weapon, but instead uses multiple small daggers and throwing knives like kunai and shuriken.
Sir Gareth of the Knights of the Round Table is quiet, serious, calm and very disciplined. But he is not without flaws: he can be rather opinionated, arrogant and sometimes a showoff. As a chameleon, he is able to render his skin to match his environment, making him nearly invisible, though he can still be seen as a blur or shimmer and something as simple as a sneeze can give him away. His armor is coated in a special material that allows it to change along with his skin. He is swift and agile, capable of running at high speeds and easily scaling and climbing up high buildings and is an expert marksmen. He is rather claustrophobic. He enjoys apples, quiet and peaceful places and can play the lute.
