Crane can consume a substance to study the composition and then synthesize it in his body, producing it in either a condensed liquid state or even as a gas. He can only hold onto five at any one time and must discard one to take on a new one.

SO BASICALLY. He could consume a poison, get fucked up by it, then utilize it offensively. He could consume an antidote and then use it like a mist spray to mass cure poisoned people. Other people would have to breathe it in / consume it though, so there's open options for player choice.
