here's a nice montage of battle set to Leo's theme music. just by watching this much you can tell Leo is the most violent of Ultra shows. it's also very dramatic, with some terrible things happening to the MAC towards the end. this is a great theme song.
it's also been one of the hardest to view. I had about 20 episodes on VHS back in the day, but not the entire series. and the episodes skipped around here and there. I think it's out on DVD now, as this clip looks better than anything I've seen.
