Ah, now we see what's going on. The three bad guys through no fault of their own thought they were capable of overtaking the Voltron Force fortress. Had they remembered that a bunch of guys, vehicles, and 200' tall robot not to mention giant lazers on the fortress itself were around, they might've rethought their flawed method of conquest. Unfortunately, my bedroom was never graced with the addition of this fortress as a child, but that's only because with Castle Greyskull, Snake Mountain, the Robo-Fortress, and the Ewok Village, apartment rental prices would've went way down with the excess rooms for rent, and none of my figures would be able to afford half those useless accessory packs they loved so much. The bad guys finally boost their forces by adding more useless hunchback monsters that can be defeated as simply as Voltron stepping on 'em.
Nobody knows for sure.
The Voltron Force was pretty confident that good would triumph over evil, but that's certainly not always the case, otherwise Nickelodeon wouldn't have been able to give us 8 hours of Facts of Life every night for a week straight a short while back. And before I go, take a look at the picture above to check out all the variations on the lionbot Voltron. These are the 'official' variations. There's also bootlegged Voltrons out there which get much more esoteric and ridiculous, with his arms being everything from musclebound human arms to giant squids. While the numbers on the lions of the show made sense, the bootlegs got a little too creative.
