FIRE!
I like this theme! There's so much potential for fire, yet it's quite a challenge to do with my 2D cartoonish art style. Plus in all capitals with an exclaimation mark, it could just be a scream for help. Or the command for a firing squad.
Voltron/Mecha Robots
Umm, maybe not the same scope as "fire" for ideas, and mecha robots will be a real pain to draw. I don't remember ever drawing a mecha robot, although given my fascination with the show when I was a kid I must have at some point. I do remember making my own Voltron out of toothpaste boxes because I couldn't afford the real toys though.
I guess I could pick one theme or the other, but it might be more exciting to attempt to combine both (although this might be a bit of a stretch for the one month deadline). Although combining "fire" and "robots" does remind me of the time I was at Robocup 2000 in Melbourne, when the Iranian Middle League team demonstrated one of the major drawbacks of basing your soccer robots around a diesel engine...
