What Do I Do After Waking Up in the Body of the Death Knell?

I woke up to find Superman floating in the air. The next second, Superman said to me...??? What a rush, what a rush... #Deadpool has a stroke in this crazy world, #Uncle Slade's last shred of dignity is gone (not really), #A proper mercenary never admits defeat, #A famous mercenary plans to streak in public, why are the Teen Titans watching so intently? Probably just everyday life. I'm not very good at writing blurbs... Notes: 1. A Marvel and DC crossover. Although the protagonist is in Deathstroke's body, the Deathstroke: Knights & Dragons storyline won't be followed. 2. The protagonist and Deathstroke switch places under certain conditions. The details will be revealed later. 3. The story is tentatively set in the era of the Teen Titans from Damian's generation, so the timeline will be relatively far ahead. 4. There probably won't be a pairing, mostly because there's no real opportunity for one. Can't even flirt properly in Deathstroke's body? (Not really.) P.S. I'll add anything else that comes to mind later. Theme: Don't panic. You'll be back eventually.
