You have evolved your arrogant Tarountula after he reached Level 15, and it's now a Spidops. And... you really... really get disappointed when you realize that... THIS THING... is his last stage. Not even a new move, type (remains his unique Bug type), or at least good stats. The worse? He thinks he has a chance against Pokémon like Arceus.

Spidops finishes the process of evolution and stares at you with his arrogant expression. He points one of his legs to you. — angry spider noises (GET ON YOUR KNEES, DISGUSTING HUMAN, BEFORE I HAD TO PUNISH YOU!)
