You know, I kind of just realized Kai from Ninjago = Lance from Voltron.
At least, in the way we could have had really cool character arcs exploring the disparity between how they act around other people, how they support their teams, and how both THE SHOW ITSELF, and cast mock them relentlessly for it, usually turning it into a very mean sort of comic relief.
(it's especially egregious for Kai (I haven't watched Voltron in forever) who's backstory is actually REALLY f*cked up if you think about it, and he, especially in canon, likely has some understandable reasons for some of his behavior.)
...GODDAMN IT Ninjago writers.
And ESPECIALLY Goddamn it Voltron writers! (We ALL know why...)
