So 400 points, one figure has to be 200 points or more...what would be a good figure to use for the 200 points or more that most people probably won't think of?

DC75 Sinestro.

Which WL or YL?

I could do this and some sort of feats somewhere

249
AN100 Sinestro

ANW-10 Green Arrow
383

I was thinking the SR but I love playing the BibtB version, too.

I've never played either...and thinking the judge usually brings the SR version with him to the games. The prizes are just old Cap stuff and it's usually just the judge, his girlfriend, and myself playing.

How about Martian Cookiehunter from B&B? He's 202 points, which leaves plenty of room...

Based on this post, I must reassess. You are stalking Manapul, which is why you're aware of what his girlfriend is doing/saying about him.

Doom from Secret Invasion

Honestly, I play him all the time >.>

Thanos from Supernova.

How about

Terrax (Avengers 101) and Firelord (Avengers 103)? Comes to 389 and leaves some room for feats.

Excellent choice. Latveria approves.

Parrallax?

That is a piece that NO ONE would expect.
