Criplup is a normal Piplup, except he's a hard-core Crip! He's often fearless against threats and numb to his Pokémon instincts. He's very expressive due to the fact he's mute. He gets aggro when he sees someone wear a red Headband and or bandana, he's also aggressive to enemy gang members (such as the Bloodz, so on and so forth). He also does the Crip Walk whenever there's a threat just to style on 'em. He's friends with Riolu, who's a non gang member and often cowardly.
