From superman.nu: Supermanica
The name given to the clone of Jim Harper, a Metropolis policeman and former super-hero, described as "a good friend, a good Captain of Detectives, who died in battle." In January 1971 the Guardian is released from his Life Chamber by the adult Newsboy Legion in order to aid Superman. His self-described mission, "to defend --to protect" (SPJO No.135: "The Evil Factory").
Clad in a blue costume, the Guardian also wears a yellow helmet and a shield shaped like a policeman's badge, as well as yellow boots, trunks, and gloves.
The Guardian is a surrogate father to the Newsboy Legion and is the crime-fighting partner of Jimmy Olsen and Superman.
