intangibility
imagine danny got caught in the dcu for whatever reason--dealer's choice (botched summoning, escape after bad reveal, natural portal, etc). bonus points if it's gotham.
he does some research (if it's a different dimension) and discovers metahumans (wow! random people can just have powers now??)
he decides he can't tell anyone he's a ghost for whatever reason, and instead has to choose a power. he settles on intangibility because it would help in self-defense purposes (gotham strikes again).
he's gotten used to using his powers freely, though, and maybe a Bat sees him fly. his excuse? "i'm a meta and i can become intangible. that includes intangibility to gravity."
he uses this excuse for as many powers as possible. invisibility? intangibility to light waves. portal-making (if applicable)? intangibility to the fabric of reality. seeing/sensing ghosts? intangibility to the boundaries between life and death.
he just keeps using wilder and wilder explanations, and when anyone asks how the hell that works, he just shrugs and says "i have intangibility and everything else is just an extension. doesn't have to make sense to you."
maybe he ends up on the justice league's radar for some random meta that could probably go toe-to-toe with most of the league's heavy-hitters.
maybe at that point, constantine, zatanna, or deadman figures out he's a ghost and danny finally gives a list go his actual powers. or maybe he just never does!
“You just made 30 duplicates of yourself! That not intangibility!”
“My future selves made themselves intangible to the flow of time, remaining in the past while time moved forward to travel a few seconds back in time and fight along side their past self, me.”
“That’s not how that works! That’s not how any of this works!”
“Flash did the same thing like 2 weeks ago.”
anytime he can't figure out a way to justify it anymore he just calls it "intangibility to the laws of the universe"
