Konsole

Konsole -

Chaos Island

Sometime long ago on Earth-101, Konsole began using Chaos Island as a soul collection point. Within the volcano was a chamber that, when someone died, would collect that person's soul and transport them to his kingdom in hell. 

One day, Konsole decided he would speed up the process by causing different dangerous events to occur every night. He started with the duel of Nico and Samm. When Nico won, Konsole allowed Nico to release Zoomerboy's soul. Next, he offered Nico and Robder cursed armor that would force them to kill one of their teammate by nightfall. This challenge alone killed Robder, Waterplayz, Zoomerboy and Doggo. The sudden increase in soul collection caused the volcano to malfunction. Lava began to rise and souls began to escape. Konsole messed with each soul, forcing them to undergo a challenge to escape.

Eventually, when Kostina arrived on the island, Konsole decided to take a step back and let Kostina collect souls for him. Kostina killed everyone on the island except for Nico, inadvertently allowing for Konsole's kingdom to gain almost every soul on the island.

Revealing Himself To Kostina

When Kostina arrived in the Shadow Realm after allowing MrFyre to kill him, Konsole found him there, disappointed with his failure to create a good ending to his story.

In the Shadow Realm, Konsole showed Kostina dreams of what his happy ending could've looked like. Following the fictional happy ending, Konsole ventured off into the multiverse to find a new universe to observe.

Unfortunately for Kostina, he woke up from this dream to realize it was all untrue. Instead, Konsole dropped him off on Earth-1A during the Undead Army Invasion to give his story another go.

Konsole repeatedly revived Kostina until he fulfilled his destiny of destroying the world and jumped into The Void.
