Michelinie, Guice and Rodier pit Superman against Shadowdragon, a modern ninja in Action 707 (Feb.95).
Shadowdragon had already encountered Superman in his own book, but this marks his first appearance in Action.
A thief, rather than a killer, Savitar uses his ninja skills to steal technology for his nation, Bhutran.
Ramsey Murdoch appears in this issue as well, murdering a scandal-ridden senator.
Superman and Shadowdragon fight when Superman catches him breaking into a computer firm. Shadowdragon does not fight to beat Superman, simply to get away, and achieves that.
The character is basically a ninja Robin Hood, and returns shortly.
