Depends on the Gundam or Mobile Suit. Some are faster than others. Gundams from Gundam 00 can use Trans-Am to get away faster. Normal Gundams using normal verniers may take some time but like I said, it depends on the actual unit.
Tch... zoids are cool and all but in a match up against a gundam there is no chance in hell that a zoid can beat a gundam. They pretty much get suited up with a whole bunch of shit like jets so they can fly, shields and swords, guns to bigass guns, I just don't see it ever happening. And anyone can use a nuke unless your talking about that one thing that that huge bronto zoid shot (too long ago can't remember) but even so a gundam can get away compared to a zoid.
if it's freedom vs zoids i still think that zoids have a little chance but not 0% of winning but still if that gundam are out of battery or energy or when battle zoids for long term maybe it will lose to zoids. anyway those zoids has more energy than those freedpm or strike gundam.. let see if zoids can move even with out those energy thinggy that will certainly win (most certainly)....
