Mobius Theory?
Loved the way this whole thing came together. It's kind of sad to see it all end really.
Though I think that the mad scientist has got to be able to find a way back into space-time, so he can try to wreak havoc once more. I can see the Time Squad returning. (Be warned, if they don't, I'm sending lots of angry emails)
And he still didn't sign Blockhead's velociraptor.
