Lampent first appeared where Trip used it to attack several rampaging Venipede in Castelia City, by using Flamethrower. The heroes tried to calm Trip down and call Lampent back, but he refused and had Lampent use Flamethrower on the Venipede leader. Ash jumped and took Lampent's Shadow Ball attack, since he wanted to make sure the Venipede were brought to the Castelia City's park safely. Ash replied they must be given a chance to prove themselves, so Trip called Lampent back and stopped attacking.
