John Constantine as a de-aged feral little shit.
Warning: Cussing
Something about John Constantine being de-aged to a ten year old or just a kid at all, just tickles my brain.
Because John '30-40 something year old con-artist, skilled manipulator, seen it all, done with everything and everyone, and is like drunk 97% of the time' Constantine gets de-aged to a kid.
Sure he'd be angry about it, cuss up a storm and cause a fuss. But think about it, it would be beneficial for him. Enemies would underestimate his strength because it wouldn't Cross their mind that this is John fucking Constantine? Literally no one because last they knew Constantine was a 30-40 year old sad trenchcoat man. Not some angry, hostile, cussing child. Only for said child to kick their ass.
It would also make getting information easier especially with ease dropping for information, because who suspects a child? (Ignoring the fact that some villains absolutely would) Morjoraity of them wouldn't think a child would be actively hunting em down.
And like sure John might have problems with being a child. People undermining him just because he's a kid, forgetting the fact that he's realistically an adult in a child's body. Only for John to shut them up with some of the most disturbing shit ever before walking away.
