A suggestion by the amazing RubyRed883!

Lloyd- Used to be Garmadon, now he looks up to Wu (and Fritz Donnegan of course)

Kai- Ray and Maya

Jay- Both his sets of parents

Nya- Ray and Maya

Cole- This one is kind of tough. I want to say Wu, since he was a somewhat better father to him than Lou, most of the time, but it's not like Cole hates his dad. Let's do Wu and his parents.

Skylor- Honestly, Kai and Nya. They have probably helped her deal with becoming an orphan. She appreciates that a lot.

Pixal- I'd say Zane and Nya. Zane because... it's Zane and Nya because of her role as Samurai X. When she realised how hard being Samurai X was, she definitely admired Nya a lot more for managing to keep up with it.

Zane- I'd say Pixal, Dr. Julien and Cyrus Borg.

Wu- His father, most likely, and I would even say Lloyd.
