The youngest member of the Strangers has grown up into a fine strapping lad, and lost none of his cheerful optimism and zest for life.
Jimmy divides his time between hanging out with his best pal Adam in Ubertopia, and working with the Council of Strangers in Paradise City, or Tokyo, or wherever he feels like on the day, really. He's even suspected to be in contact with the renegade King Zero, but isn't letting on to anyone if he is.
Jimmy's nuclear metabolic cycle has slowed down a bit as he's gotten older, to the point where it cycles between peaks over the course of a minute or so, allowing him better control of his fluctuating strength and invulnerability. According to tests by Adam Zorn, he's only a few years away from being able to safely remove the Gamma Gauntlets for good.
