Honestly yeah I was having a similar thought process given some of his, ahem, characterisation
That said, Doctor Manhattan could probably be made to work! You could probably give him a decent variety of moves and I'm sure there's enough potential for him, it might just feel a little odd if he gets killed by like Marvin the Martian lol
I'd personally say it'd be really cool if he had a teleportation move but with a visual effect that makes him look like he's "disassembling" his body into a skeleton, kinda like the visual effects in Snyder's
Watchmen film - obviously they couldn't do it in too much detail but I feel like him manifesting as a nervous system, then a skeleton, then fully formed would be a really cool bit of visual flair
Also completely unrelated but I just had a weird thought. With discussion around
Pickle Rick being pretty commonplace as well as the obvious elephant in the room being UI Shaggy, it's pretty clear that literal "meme picks" aren't off the table - do you think there's a genuine possibility of Batman recieving a "Man" skin to represent the iconic Arkham Aslume series?
