Shadow is an enemy in Wario and Waluigi's Super Adventures, and the star of Shadow's Stupid Adventures. Shadow is a dumb hedgehog who can never seem to come up with a good pun. Sonic created him with a very expensive Shadowball (like a Pokeball, but spawns Shadow rather than a Pokemon). Shadow is Sonic's slave because of all the terrible things he had done to Sonic and his friends over the course of the first season of Wario and Waluigi's Super Adventures. Shadow often escapes Sonic's control though, such as when he escaped and became King Dedede's spy in Wario and Waluigi's Super Adventures, and when he betrayed him in Super Smash Bros Plush.
- Although Sonic programmed him to be smart during his creation, Shadow is proven not to know the full alphabet, stating that the ABC's goes like, "A, B, K, L, 9, 8, Jimi Hendrix, 1592, 12, the end!".
- Shadow is terrible at Wii Fit.
- Shawdow is the only character who was legally released from jail in Wario and Waluigi's Super Adventures.
- He won third place in the 2011-2012 MLPB Awards for "Best Quote".
- He loves Claw Machines.
- Sonic's Clone gives Shadow cookies.
- Shadow is the only known character in MLPB to have a creation from a Shadowball.
