I don't think Nintendo is taking inspiration from Sonic because of those tiny similarities. I think that with Shadow, it's actually the other way around. Just look at Giygas(alien from the Earthbound series who was raised by a young human woman named Maria and after she was killed because the great-grandfather of one of the playable characters did something that was deemed dangerous by the alien government, he came back a few decades later to destroy earth but was "defeated" by remembering his feelings towards her) and Mewtwo(man-made Pokémon that was unsure about it's identity and what it was supposed to do with all that power it was given but was redeemed in the end and on top of that, based on Giygas design-wise). There's only one Pokémon where I would question it, and that's Lucario from Gen.4, being a Fighting type Pokémon with spikes on it's fists, dreadlock-like hair and an oddly shaped tail that can feel aura as well as learn the attacks Dig, Extreme Speed, Close Combat and Heal Pulse and even is a guardian in PMD.
