ok so if you need a spoiler-free explanation, this should be good, like if you're trying to tell someone about it without spoiling it for them, then this should work. Please don't back out and say its lame if all you have to go by is this spoiler-free description, its actually an epic show, trust me on this. So basically, there are 5 giant robot lions that are Blue, Green, Red, Yellow, and Black. They're piloted by people called Paladins, who are chosen by the lions based off of qualities (like, personality, and also what kind of person you are, ie Leader, Planner, Loner, etc). The lions can combine to form an even bigger robot thing that is literally the most epic thing ever if you can get over the fact that it has lion heads for hands and feet.Oh, and it can like shoot lasers n stuff. And then just fyi, there's a lot of fighting (but not much gore, like, at all, so don't worry), and it gets intense, and also stay away from spoilers if you know what's good for you.
even quicker summary of the basics: > Main setting: some kind of spacecraft or in the middle of space > Main concept: Voltron basically just spends most time fighting these aliens called the Galra Oh, and, important terms: > VLD = Voltron: Legandary Defender (the fandom usually either calls it Voltron or VLD) > Quiznak = altean swear word, one creator says it means "dang it", but based on how it's been used, I'd beg to differ > Galra: main alien race that they're fighting against for most of the series Hey, I managed to make a description that doesn't even spoil the first episode that much, past the basics ofc.
