Shadow the Hedgehog (Sonic Boom)

Shadow the Hedgehog is a major antagonist in the Sonic Boom spin-off franchise, serving as a supporting antagonist in Sonic Boom: Rise of Lyric, an anti-hero in Sonic Boom: Shattered Crystal and a recurring antagonist in the television series. He is the rival of Sonic the Hedgehog, who seeks to prove his superiority over him in every way. He is also notably darker than his mainstream counterpart, and has shown to be more of a villain than an anti-hero.

Why He Sucks

 * 1) He's not portrayed as the same likable anti-hero that has a sympathising backstory and his huge goal of protecting the Earth that everyone loves. But instead, he's portrayed as an evil generic bully with no backstory behind his cruel behavior.
 * 2) He hardly has a single bit of motivation to anything he does or will do. Which makes his character completely lacking depth.
 * 3) He often antagonizes Sonic and his friends for really no good given reason. Even though he doesn't really have much reason to.
 * 4) He has tried to destroy the planet a few times, and he never even gives a single bit of info to why he wants to destroy the planet.
 * 5) With all the lack of motivation and depth that this version of Shadow has, it basically makes him hardly have a single bit of identity outside of a generic bully. Which just makes him an uninteresting and unmemorable character, with just so much inconsistency.
