I choose the all mighty Lexx, the most powerful weapons in the known two galaxies.
Starwars is a bunch lasers, and people playing with pixie sticks. In Lexx we have bug weapons, and blasters that can disintegrate in seconds.
Star Treck, might be good for a laugh, but apparently Star Fleet are the weakest link in itself. Torpedo's, give me a break, the Lexx blasts can cut through entire planets, in a second, and even dodge torpedo's.
Clingon invasion, the Lexx will just absorb them into it's system, or expel them. We have the almighty Captain Stanley Tweedle, Zebbs the man eater, and of course Kai.
Lexx destroyed the earth, so Star Fleet does not exist, and I am sure the Lexx could blow up death stars faster then they could maneuvers. including those god forsaken star destroyers ( why do they call them that, if they do not destroy stars??? ).
Nothing else is bigger then the Lexx, and I am the Enterprise would be up to it's neck in webbing, if they had to put up with the crap, the Lexx did.
Imperial Storm troopers? Ha his shadow has waves and waves of brainwashed slaves, kinda like the United States has all those people joining the military, but everybody is drafted. Their are sex slave plenets, in the cluster compared to green Venusian women. In the cluster everybody worships his divine shadow, then getting a pay day.
About the Divine shadow vs the Emperor? His Shadow is the dark side, in the flesh, might be a giant big bug, but at least he is not a crippled old man. One well placed blast, of his shadows energy.
Earth final conflict, V, or even Andromeda has nothing against the mighty Lexx. Speaking of which how did "Captain Symian, and Space Monkeys ended???
Fasers? we got flack packs...
