Adventure Time Comic Issue #14

Ewlbo (now going by the name "Kewlboy" after overwriting Randall) is attacking Finn, Jake and Marceline in a giant robot body made out of all the robots inOoo. They attempt to attack Kewlboy, but they can't seriously damage him out of fear of harming the robots. Kewlboy reveals that his plan is to destroy everyone in Ooo out of fear that they are all "better" than him. Jake  attempts to stretch him around Kewlboy in order to restrain him, but to no avail and Kewlboy appears to have smashed him into the ground. Marceline attempts to reach out to Randall, Kewlboy insists he was deleted, so Finn and Marceline decide to throw caution to the wind and attack him directly but he grabs them. Before he can pull them apart Finn reveals that Jake was okay and had just shrunk into his mouth.

Jake uses his stretching powers to press BMO's hidden button and send the three of them into his Main-Brain-Game-Frame. There they find the minds of the infected robots and they are able to use a cheat code to rid them of Kewlboy's virus. However, Kewlboy appears in the game and reveals that he still has control of BMO and sends waves of the game's enemies to attack them. Marceline has the robots with them combine into giant mechs for the three of them to fight off the enemies and then attack Kewlboy directly, tearing the pixels off his in-game figure and feeds them to the game's enemies.

Back in the real world, BMO has returned to normal and suggests they go play video games, which everyone agrees to.

Later, in the game, Randall appears and reveals that while Kewlboy deleted him, he never emptied the trash. Randall has learned he was wrong to have tried to find cheats for all his games and decides to play with the rest of them honestly and they go off to explore the game's universe.

Finn, Jake and Marceline discover that the virus that has infected BMO has infected all the robots in Ooo. For some reason all the robot have gathered around an abandoned military base and BMO begins to get an unknown system update and begins to reboot. This update allowed Ewlbo to install himself into BMO and all the other robots and remove their personalities, effectively killing them.

Because they're outnumbered they can't fight the robots off and they don't want to destroy them in hope that there's a chance to save them. They decide to try and hack the robots and go inside the military base and see that the power still works. Marceline reveals that before magic became popular, she studied computers and is able to hack the virus code. After finding an oddly named program file, goggles fall from the ceiling and when they put them on they are transported inside the computer mainframe and meet a software version of Randall N. Byron, the creator of Ewlbo.

He explains that over one thousand years and twenty-three years ago he was born and one thousand years and two years ago the world ended and between that time he wrote computer programs. He was most interested in games a wrote a self-replicating code that "seeks out games and gives you better dudes" and it made his video game characters stronger. After the first Mushroom War the code spread from system to system trying to survive until it got to the military base and  met the Omega Algorithm, military grade software designed to destroy whatever target system it's installed into. After Byron's program attempted to infect the Omega Algorithm it adapted to the program and fought it for two weeks and then merged with it, creating a new program that "systematically seeks out and destroys better dudes" and BMO was infected when he dug up Super Guts Punch 3 and wirelessly spread it to other systems.

Randall decides to merge with Ewlbo in hopes of controlling it but the Ewlbo virus is able to overwrite him and confront the trio in a giant amalgamation body made of all the robots in Ooo.
