The Prankster has a svelte new body and far better teeth as of Adventures of Superman 579 (June 200), by Jean-Marc deMatteis, Mike McKone and Marlo Alquiza.
But aside from his new look, his actions are much the same, pulling off elaborate gags designed to irritate Superman, and bring himself attention.
Superman also has to deal with the Adversary, a somewhat ridiculous looking villain who Superman has no time to waste on.
But the Prankster has picked the wrong day for it, as an ailing Superman is far more concerned to find Lois Lane, who has gone missing. Superman suspected Luthor was behind her disappearance, but his confrontation with Lex gets interrupted by the Prankster.
As it turns out, both the Adversary and the Prankster get away from Superman, whose ailing condition has resulted in him turning green.
The story continues in the next issue of Action.
