I love Shadow the Hedgehog, he's my favourite sonic character!
So, I made a new sibling for him hehehehe >:3

Some random stuff:
-Ecco thinks that Metal Sonic is really cool
-Really likes the Chao that look like Shadow
-They can go super with the chaos emeralds
-Forever neutral face. They could be the happiest on earth, and the best you get is a small smile
-They love the brownies with the colourful candies
-They have a lot more chaos energy than shadow because Ecco is the first prototype of G.U.N.'s making that actually kinda worked...
-Wolf and bat hybrid! (Werebat!!! :3)
-Would bite, and could, and you wouldn't be able to escape because an overpowered child lol
-Mimics Shadow a lot

Also their name is Ecco because they're Shadow's distant echo :3
