His design is nice, backstory pretty interesting, his character is better that the fandom ought it to be, and the Boom franchise is trying to ruin him for real isn't it.

He was created to become a weapon, grew with a human who tried to bring the best out of him instead of that weapon he was made to be, lost this human for a gunshot and was sent to earth to sleep in a capsule for 50-years, only to be awaken to wreck Sonic's butt and collect dem chaos emeralds only to then realize that Sonic wasn't a bad guy, so he became this frenemy rather than picking a side. Shadow the Hedgehog in Sonic the Hedgehog (aka Shadow in Sonic 1) is a fan-made ROM of the game Sonic the Hedgehog for the Sega Mega Drive, with Shadow the Hedgehog as a playable character in place of Sonic the Hedgehog. Okay setting aside all the talk about him being emo and edgy (he wouldn't seem so edgy if he wasn't black and red and grumpy looking, just saying), he's pretty badass. is descended from BOTH Sonic and Shadow Its easily possible, all that needs to happen is any of the twos descendents to hook up and. He still does but the franchise and fandom have done so much to ruin this character the best they could.

Shadow was my first favorite character in the Sonic franchise after I got into the fandom, only for his design tho.
