Marvel: I Started by Containing SCPs

A car accident transported Ryner to the perilous world of Marvel. But it wasn't just the Marvel world; the entire multiverse was at risk of being invaded by containment objects from other worlds. Fortunately, Ryner received a system from the SCP Universe that could predict which SCP objects would invade which worlds. By announcing the invasions in advance and issuing containment missions, he could gain the characteristics of these SCP objects and countless rewards upon successful containment. Thus, countless worlds across the multiverse began to descend into madness! A statue that twists your neck if you look away! Plants with incredible reproductive abilities! A shy creature that hunts you down to the ends of the earth if you catch a glimpse of it! A terrifying creature with infinite regeneration and evolutionary capabilities! Tony Stark: "What are these monsters? My armor legion can't handle them at all!" Bruce Wayne: "With such outrageous containment objects, how are we supposed to complete this SCP mission?" Sengoku: "Damn it! How are we Marines supposed to deal with such monsters?" Jiraiya: "I thought I had seen a lot, but the world is much bigger than I imagined..."
