Fatalities
Rick's Gym (Johnny Cage)
Rick reaches into his pocket and pulls out a needle full of steroids. He injects it into his arm and, regardless of his form, turns into the muscle bound Rick. The scientist then pounces forward and traps the movie star in a Lou Thesz press. Pulling his fist back, he then unleashes a torrent of punches that bloody his fists until he delivers a double axe handle that shatters the skull. He stands up and spits on the headless carcass.
Operation Phoneix (Kotal Kahn)
Rick looks at his body before he pulls out a dart gun. He places it on his neck and drains some blood before shooting it at the emperor. Rick falls over and the god thinks he's won, only for his gut to start hurting. Shouting in pain, his body burst open as a baby Rick shots out of his blue chest. The baby rapidly grows into adult Rick as the god falls face forward dead.
X-Ray (Predator)
Wriggity-Wriggity-Wreck
Rick fires a laser gun, dazing the alien before he walks forward and kicks the creature in the testicles, breaking its pelvis. The scientist then delivers a hard punch to the head, cracking the skull and letting brain fly out. The old man then raises his leg and delivers a solid kick to the gut, cracking the ribs and sending the hunter flying backwards.
Victory Pose
Rick wobbles to the side as he pulls out his flask. He takes a victory drink before falling over drunk.
Ending
Rick Sanchez never set out to be a hero, nor did he want to be. He didn't care about other worlds or dimensions, he cared only for what he wanted. Imprisoning Shinnok in the amulet once again, Rick then stole it and created a device to harvest Shinnoks power... to operate his car. With no more need for his dimensional battery, Rick finally proved who was better between him and Zeep.
There was no way Rick was going to be acting altruistically if he came into this universe. So I gave him a selfish reason and stuck with his personality. Now here are your next options; Natsu Dragneel or Spider-Man. Tell me who you guys really wanna see next.
