He looks like an OC made by an edgy Tumblr user (pale twink with multicolored hair and an ace flag color scheme), his name sounds like something that Tumblr user would name said OC (a masculine derivative of amethyst), he uses Pokémon said Tumblr user really likes because of the edginess, and he sounds like the Sonic character that looks like an OC made by, you guessed it, the same Tumblr user.
He would secretly use Tumblr and post dark aesthetic images of armor, swords, and fire. He would go by "Cerulean" or some derivative of cerulean online so his lackeys don't tease him for using Tumblr, but it's really obvious to them that "Cerulean" is Amethio.
He would unironically say "While you were busy being heterosexual I studied the blade" and then follow it up with "The soul blade" or "The bitter blade" or "The cerulean blade" or something like that, then have Ceruledge slice the opponent to ribbons with the move Bitter Blade.
Between Project Shadow, Sonic X Shadow Generations, and Sonic Movie 3, Shadow’s going to relive a whole lot of trauma, huh
When I draw, I tend to make the facial expression of whatever character I’m drawing. I starting tearing up while drawing this and probably scared everyone around me haha
Late at night, they're asleep
I'm awake, get the urge
Hit the street, jump a curb
Alleyway, dark and wet
Set the trap, I forget
Who I am. But I know
I'll get you . . I'm so bad
