I doubt a bowie knife would be enough to slay a Ro-Man. Heck, one of 'em wiped out humanity, who were using H-bombs against him!
Plus, what about their Calcinator beam?
It's a bit late, but your readers might like to know that Stardust's creator, Fletcher Hanks, has a couple of retrospectives out: "I Shall Destroy All The Civilized Planets!" and "You Shall Die By Your Own Evil Creation!" They feature his work for Fox Comics with Stardust (and my personal favorite, Fantomah). There's also an omnibus collection, "Turn Loose Our Death Rays And Kill Them All!" Well worth the money.
