This one is a history in the making because I have not drawn Allura. At all. And this is her Legendary Defender counterpart. While LD was proven to be divisive among the fandom, I'd say it's the best Voltron series we've got. Say what you will, but hear me out. I've seen Defender of the Universe. It didn't age well at all. Even as for nostalgia/hardcore series, it doesn't win. GoLion, while a marked improvement of the DotU (Lion Force), it was boring and didn't age well either. Vehicle Force and Dairugger, even more boring than the lion counterparts. Albegas, there's still 2 episodes officially subbed on youtube and I have no idea when they'll finish it. 3rd Dimension, not as good by comparison, but I happened to like it. Hell, that series was my introduction to Voltron in the first place weirdly enough. And then there's Voltron Force, definitely the worst one for me.
