Shattered Dimensions: Marvel x DC

Zombie virus swept over the world. Heroes are either dead or turned zombies. Humanity is fighting for survival, but as time passed, humans become more vicious than those freaking zombies. The lack of resources turned humanity against themselves. Among those survivors, there is a boy named, Karl. All he wanted to do was survive with his family like all others, but that changed when Karl awakened a unique System that provided him with quests and rewards. However, even with the system's boost, will Karl be able to protect what he has and face off against zombified heroes and villains with intelligence? What if the Gods themselves are corrupted by the virus? --- There's a harem. MC will travel to DC too... --- I don't own Marvel or DC except for my own OC.
