I'm okay with them as long as they leave me alone. I have had no problems as of yet, but the future may hold different. Who knows. I am slightly bugged by designs, but I usually excuse it as the fact that you sometimes can't make the character with the in-game markings no matter how hard you try (and sometimes downloading markings won't help). Other times it's the names. I have names such as Leo the Leopard/Panther, Batti the Bat, and the Glitch (dunno what his name was, but he is a wolf and deactivated). I see these crazy names, and i'm like...these are things that kids were supposed to know and love XD! Just like Turtlex, it's just a little nitpick. I even kinda go insane over the names not rhyming e_e. Dunno why, I just do.
As for powers, since I have yet to actually roleplay with one...I can't say I have seen those myself. If I do, I will start internet slapping people >:I (though Bonnie does appear to teleport in game, but I think he's just THAT fast).
