So here's the deal-- Vulkor the Capsule Master is not getting the love and respect he's owed around here. He was the villain of the first ever Brave and the Bold team-up, and the first Martian Manhunter-specific villain powerful enough to require outside heroes to defeat. Vulkor is admittedly silly looking, but his debut was important enough to warrant reprinting at least three times to date, and he's way more competent than a lot of better regarded Vile Menagerie members. Vulkor has yet to make it out of the first round in one of our March Madness contests (though he probably defeated someone in the unrecorded qualifying rounds in their initial year.) I hope this match will be an opportunity to rebuild his reputation.
I've never been impressed with Ocean Master. Aquaman still has only two villains that most folks can be bothered to remember, and Orm is the other one... the one who wasn't in the Super Friends Legion of Doom; the one who didn't murder Aquaman's son; the one who didn't turn up until Geoff Johns' third year writing Aquaman, after he'd already done two extended Black Manta arcs. The recent "Throne of Atlantis" crossover arc was probably the biggest story of Ocean Master's career, but he still got beat down like a punk in the span of a few pages. Vulkor's a Martian, he's got Martian henchman, and I'll pit his capsule against any of Orm's silly fish-ships.
