Haven’t gotten nearly into this, but it sounds interesting and (potentially) well thought-through. Chima was the embodiment of what “wasted potential” looks like.
An involuntary smile appeared on my face when I read Laval’s character description. 
EDIT: So the biggest logical falacy was definitely the math going into the Lion’s Chi reserves - it makes the (unjustified) assumption that Chi is produced at a consistent rate, when it might actually function more like a geyser and release it in periodic bursts. It’s still pretty hard to reconcile the math though, unless this happens really really infrequently.
Definitely a… colourful take (the War Crimes section was an amusing read) but I’ve got to admit when I was first exposed to Chima, and was a far bit younger and less objective/critical, I still genuinely found the bad guys to be more relatable, compelling, and justified (not saying a lot, but still).
I didn’t watch anywhere near the entire show but I remember Laval being obnoxious (like, I don’t mean in the “oh, I find him annoying” sense. He was pure frustration to watch), Eris being… well, nowhere near as intelligent as her Lego.com bio suggested, and Cragger being impulsive but not really that evil. Regarding the thing with his parents, I distinctly remember also thinking “that was clearly the Lion’s fault” - it was almost Invasion From Below levels of contrived drama.
From memory, there was a peacock? Didn’t see mention of him. The second/third years also don’t get much analysis but I didn’t follow them closely anyway.
Chima could have been so cool. It was clear that the intention was to create a science-fantasy animal world where each faction had unique traits to distinguish them and valid motivations behind their actions. It’s a shame that the stark “good/evil” narrative got imposed on a template that clearly wasn’t designed for it, and that the good guys arguably got the short end of the stick, for once. Quite disappointing that such a unique (and yes, bit crazy, but that makes it fun) premise ended up like… well, this, instead.
