One thing that really bugs me is his name. Red Volcano is much more a name evocative of say fire than Earth particularly since he's always molten but I guess Red Tremor or Red Earthquake would sound silly.
To be fair, they need to go with the -o theme.
(As a side comment, somebody really need to repost stuff from the the spoof DC -o team villain team up, the one where T.O. Morrow is scandoulous found to have a W at the end of his name.)
Morrow's been popping up a lot lately, between here, Wonder Woman and Booster Gold.
