GYGO, SotC, and other acronyms

So, I'm lined up to run a game of Spirit of the Century for the next Get-Your-Geek-On-A-Thon in less than two weeks. At the moment, no one's signed up for the game... but I've learned to expect that more people show up than sign up, so I'm gonna do my best to be prepared.

And that means pregens.

My basic idea is to have 5-7 pregens there for folks to choose from, with Phases 1 through 3 already completed; people will pick the character who interests them, and then everyone will do Phases 4 and 5 as a group. (For some background on Phases, you can check the preview document here.)

So, what I'm asking the creative braintrust of my friends list for are basic character concepts: cool pulp names with associated one- or two-line descriptions. contentedmoo has graciously offered to help me flesh the concepts out with Aspects, Skills, and Stunts -- though if y'all are rules-savvy and have suggestions along those lines, they'd be welcome.

My example, to get the ball rolling: Brick Hauser, Man of Granite. A dockworker-turned-crimefighter gifted by SCIENCE! with nigh-impenetrable stone-like skin and inhuman strength!

So, any ideas?
