A Real American Hero comics continuity - Marvel
- In the UK, he was a basic "Cobra" with no mention of the term "Iron Grenadiers."
- Voltar is one of the villains never to appear in the 1980s Sunbow cartoon in any way, shape or form. This is because an animation model was evidently not ready, which is why he was never even animated for commercials.
- Despite the codename, it's possible that Voltar's pet is not a vulture, but a condor. In fact, until shortly before release, he was going to be called Lord Kondor.
- Other working names include Graf, Madagascar and Field Marshall Null.
