I'm sorry, but I'd prefer to keep it random so everyone who opts in gets an equal chance at all of the varied powers that will be on the table. If you really want a less random power share, that's probably more of a personal plot idea for you and the other player to work out separate from this bit of Fandom wacky. Or there's always the gamble of signing up and crossing your fingers. I swear on the mind ghost of Peter Parker that the RNG will be fair if you go that route.
