The general plot of Cycle is that you play as a sporeling named Xander that was created by Poison Ivy (and Harley Quinn to an extent) during an event known as a dimensional quake. These dimensional quakes are essentially incursion events (see the Marvel Wiki for a proper definition) that are causing multiple realities, mainly ones from comics, to combine with one another. It is your mission as Xander to find out the cause of all these quakes and put a stop to them before all realities are destroyed. Plus you get to fuck a bunch of comic babes along the way.
Currently the POC has access to 70+ scenes via it's cheat accessible scene gallery, with roughly 10 or being available during normal gameplay. It also allows you access to several battles, including multiple boss battles, along with basic items.
