Vector Prime

Fangar was the only one that was actually seen in his "cured" state in the TV series. The glow just disappears from the Hunters.

Just because Wu hasn't been seen yet doesn't mean they've killed him off. He could either be in the summer sets (like Nya was last year) or he doesn't play a big enough role in this season to get a minifigure. My guess is that if a sensei does go with them to the island, it would be Garmadon and Wu just stays behind. Though if my prediction is anything to go by, I'd guess that Garmadon doesn't arrive on the island until after the tournament is over and they start battling the snakes in the jungle.

Sweet. Is the Ice Bear's name "Icerlaw" or am I misreading it?

Not sure where the idea that the other snake is Arcturus came from since Arcturus lived a long time ago and was just briefly mentioned as a posible solution to the codename. Though I suppose it is posible.
