Evan debuted in Lapras Lazily in a flashback. After witnessing Blue catching a wild Lapras, Evan appeared and demanded that he give it to him, as he was hoping to catch it first. When Blue refused, Evan admitted he only wanted Lapras so he'd have something to help find his missing Haunter that flew to the towards the Power Plant and never returned. After Blue agreed to help, he and Evan traveled to the Power Plant.
In Electro Magneton, Evan and Blue encountered Agatha of the Elite Four. Agatha had lured various gas Pokémon to the Power Plant so she could catch them, Evan's Haunter included. During their battle, Agatha had her Gengar trap blue in a coffin that slowly sapped his energy. With words of encouragement from Blue, Evan managed to find his Haunter and had it face Gengar. This distracted Gengar long enough for Blue to break out and defeat Agatha's Pokémon, forcing her to flee. Afterward, Blue thanked Evan for his help and released Lapras so Evan could do whatever he wanted with it.
Two years later, in Putting It on the Line...Against Arcanine, Evan was revealed to have become a Camper. After she arrived on Cinnabar Island, Yellow met Evan while he was gathering stones littered on the ground. Evan used the stones and his Pokémon to help Blaine train with Mewtwo. Once their training session ended, Blaine thanked Evan and paid him for his efforts.
In Bang the Drum, Slowbro, the Cinnabar Gym was attacked by a multitude of Dragon-type Pokémon commanded by the Elite Four. Evan and Miles kept themselves hidden while they waited for Yellow and the Gym Leaders to defeat the Elite Four.
In Oh, It's Ho-Oh!, Evan and Miles entered in the Pokémon League. As they had no Gym Badges, they had to take part in the preliminary rounds. Due to the Masked Man's attack on the Indigo Plateau, the tournament was canceled and they never got a chance to compete.
In Double Down Deoxys, Evan and Miles were seen visiting Blaine at the Cinnabar Gym.

At the Power Plant, Evan managed to find his Haunter and used it to distract Agatha's Gengar long enough for Blue to defeat it. Later, it fought against Miles's Persian at the Indigo Plateau and won.|
| Arcanine is Evan's second known Pokémon. It was first used to help Blaine and Mewtwo train. It used Ember to set the stones Evan collected on fire so that Mewtwo could deflect them.
Arcanine's only known move is Ember.
