Sonichu may be the protagonist (albeit in name only), but he's outclassed by almost every other Sonichu in the comic. Almost everyone but him is dual-type, and all because Chris is too lazy to even rip off existing Pokémon (other than Pikachu/Raichu), so he just takes Sonichu, recolors him and adds another type without removing the Electric. Everyone can use more than 4 different moves in battle for some reason too, so he doesn't even have that. Sonichu is shit compared to almost every other character of his same species. He's like an autistic Eevee, except the superior ones aren't his evolutions, but members of the same species that somehow got another type.
tl;dr: Sonichu is shit because Chris fails at Pokémon
