Which of These is the Better Undead Villain Faction?

It’s kind of crazy to think that throughout the years, Ninjago has had quite a few villain factions that share one common similarity, being “undead.” We’ve had quite a few undead factions throughout the years. So, out of all the ones we’ve had in the original TV show, which one do you think is better and why? They are the skulkin from the pilots, the ghost warriors from season 5, and the re-awakened from season 13. Im curious to hear your thoughts. submitted by /u/Lil_Critter_2001_ ...
