- -- Diamond Jack src
"Diamond Jack" Lansing was given a magic ring, by an old magician, and thus became mentally and physically strong beyond mortal limits.
- Magic Ring
- Lansing's Ring can transform one life form into another, for example a rampaging Vulture-man into a saguaro cactus.
- It can cast mirages, flash blinding light, or conjure a flaming sword out of mid-air.
- "ADKHEL!" might be a magic word; Jack says it as he is using the ring to explosively destroy a dam.
- Diamond Jack would kill a villain with no compunction at all. In his final story he drowned several dozen formerly-human Vulture-men, along with their creator Kruger.
