Indeed, judging by the one story I've got, the strip has very little originality - his skills are the Green Arrow's, his secret identity is Superman's and he's got sidekicks and a stupid interfering cop antagonist straight out of The Spider. To be fair the strip here seems to be a later one which drops the original medieval-style hooded costume (which can be seen at International Hero) for a black number which doesn't even hide his face. It's pretty boring actually - especially considering how superb the cynical, grumbling Archer is in Zenith.
This story is from a 1985 edition of Eagle Picture Library, but if there's any doubt it's from the sixties, check out Chango's vely lasist speech patterns. Just to make sure we know he's Asian, he's randomly karate-chopping something the first time we see him too. Bolts of steel!
