Steven was once an ordinary trainer living in Pallet Town's outskirts with his starter Charmander named Miki, alongside his brother Mike. Just like any ordinary Rival Battle, Miki and Mike's Squirtle fought, with Miki being the winner. Steven seems to have already built up a reputation around the town, with Red looking up to Steven, and is currently in a relationship with Daisy Oak.

Like any other game, Professor Oak gave the two brothers Pokédexes as gifts, and wished them luck on their adventure.

The game continued as normal, albeit with a few story changes. Steven's fame spread as he swept through the region, earning his badges. Throughout the adventure, Miki grew as well, growing into a Charizard.

The only notable change during the main gameplay is with Pokémon Tower, with Steven outright refusing to go inside, claiming to have no business there. Other than that, the player continued on as normal.

Steven would defeat the rest of the gym, the Elite Four, and eventually his brother in one final fight before becoming the champion of Kanto.

Back at home, Steven and Mike would have a conversation, with Mike begging the newfound champion to trade Miki with him in order to complete his Pokédex. Steven would reluctantly agree, before a malfunction caused a loud "SNAP!" to be heard, and the game froze. When the narrator turned the game off and on again, the Charizard was missing.

Miki died.

One year later, Steven was at the Pokémon Tower, still mourning over his loss. All the Pokémon obtained on the journey, all of his money, his badges, everything he had ever collected was gone. The previous champion of Kanto had given up, leaving the spot open for some other kid to take.

Steven would shamble around from place to place, absolutely broken over the loss of Miki. Wild Pokémon would leave him be, and the people of Kanto would try to comfort him, to no avail. Eventually, Steven would tire out and go to bed, where he gained a terrible idea.

Steven would swim all the way to Cinnabar Island, where he would encounter "the missing one", MissingNo. With just a single word, MissingNo suddenly joined Steven's party as an item. Steven would swim all the way back to Lavender Town, and used MissingNo on Miki's grave.

It worked, but imperfectly. Miki had become corrupted beyond belief, and is only recognized as "M@#$". This didn't matter one bit to Steven.

Steven would slowly make his way back to his home, and stood at the foot of Mike's bed. Inspecting the menu, the only option that worked read "STRANGLE". The screen cut to black as another sickening "SNAP!" was heard, and the game reset itself to how it was at its beginning.

Son of a threat, Steven stole all Mike's pokemon! He strangled his DS!

Steven is a Pokémon trainer with a red vest, purple jeans, and a red cap with a white front. He has long, black, unkempt hair. In his song, Steven's eyes are always framed in shadow, unable to be seen. He's tan.
