Kai is a Decoy ProtagonistLloyd will become The Hero of the next season and Kai will be his Big Brother Mentor instead of the Supporting Protagonist. The season will probably revolve around him learning the ways of spinjitzu and shifting into his role as the Green Ninja.
In season 2, Slithraa will return as Lord Garmadon's Dragon and take back his place as general of the Hypnobrai.Jossed all of the Serpentine general (minus Skales) act as his dragon.
Towards the end of season two, someone is going to find a loophole or way to cure Lord Garmadon of the Great Devourer venom so Lloyd won't have to defeat him.Or that's HOW he defeats him. The prophecy says the Green Ninja will defeat Garmadon, not destroy him.
Lord Garmadon and Lloyd will eventually be turned back to normal.It's just really sad keeping them as altered as they currently are...
Dareth will eventually join the team and become a real Ninja.It would be a shame if he never appeared again, especially after all he did for the team and his dream of becoming the Brown Ninja.
Dareth is the real Second Ultimate Spinjitzu Master.Dareth does seem to be a bit a goofy, but anyone can unlock their full potential. As said before, he has helped out. Also, he seemed to be immune from the dark magic.I never heard in the prophecy that the Green Ninja would be an Ultimate Spinjitzu Master, just that he would have his powers.Dareth's dojo class could be the next Ninja and he would be a real Sensei.
The First Spinjitzu Master is an incarnation of the Golden Dragon...Or vice-versa. We know from leaked 2013 set descriptions that there will be a Golden Dragon in 2013. In the episode "The Stone Army", when Misako is describing the history of ancient Ninjago, we briefly see such a figure before the image transitions to an image of the First Spinjitzu Master... much as if one is transforming into the other.
Misako was Sensei Wu's lover before she had a child with Garmadon.Of course, with this being a kid's show they wouldn't describe it in that exact fashion... but based on her and Wu's interactions thus far it's a possibility.
Ninjago is in Europe or is Europe (perhaps Eurasia).The map shown in "Ninjaball Run" resembles the continent.
The theme song line-up of ninjas and their allies will include Garmadon and (maybe) Zane's creator or Dareth.
The Overlord became the Darkness when he was defeated. When he was defeated by Llyod, he was thrown out of the Ninjago universe and entered ours. He was weakened by Llyod's final attack, which made him vulnerable to light and unable to exist by himself. He required a host to survive and gave his host weakened forms of it's original form. However, he was also to take control of his host as he did with Lord Garmadon if they continue to empower him.
There will be a sequel series, with Zane training the next generation of ninjas.As an ageless Ridiculously Human Robot, he is probably going to "far'' outlive his True Companions. After having a Heroic BSOD and then spending some time meditating, the sequel series will have him as mentor to the next generation of ninjas, far in the future.
The series is being acted out by one of the future children of the main characters as his/her father tells him/her about his adventures.Quick, someone fic this.
Extended exposure to spinjitsu extends your life.Sensei Wu and Misako certainly seem to have lived an unusually long time.
Pythor isn't deadThe Great Devourer ate him and Sensei Wu at the same time and Sensei Wu turned up OK aftter the Devourer exploded. Pythor is presumed dead because he was nowhere in the remains of the Devourer. But remember how his special ability is turning invisible? Him sneaking away invisibly makes more since than him getting digested while the guy who was eaten at the same is perfectly fine.
The Serpentine is a lost Chima tribe.What's the motif of the Legends Of Chima sets? Anthropomorphic animals with ridiculous-looking vehicles modeled after themselves. The Serpentine fit the bill perfectly, especially when the Fangpyre's vehicles are taken into account. Somehow, the Serpentine must have gotten separated or banished from their fellow Chima tribes and ended up on Ninjago.
Zane will have a 'Your kind or your friends' dilemma.The names of the new Ninjago sets suggests a robotic theme. This will lead to one of the robots trying to appeal to his robotic side and join them. The ninjas may also use more force against them since they're 'just machines', leading to some bad blood between the ninjas and Zane.
The reason we haven't seen the figure of Zane yet is...
P.I.X.A.L will betray the ninjasJust because.
The show takes place in the same universe as The Lego Movie.
As a Shout-Out to The Lego Movie, Lloyd will have to leave at a random time to attend a Master Builder meeting.
Pythor and Samukai are both incarnations of the Overlord... so at least one will return.
The Anacondrai are serpentine of creation
After finding his way back to New Ninjago City, Garmadon will convince the serpentine to help rescue his son.True, Skales did say that the serpentine swore to never return to the surface, but I don't think the show would bring them back just for a small role (especially give their popularity). The serpentine are probably going to play some bigger part later in the season, perhaps helping the ninja to stop the Digital Overlord. And considering that Skales has a family now, he might be persuaded to lend a hand if it is made clear that the Overlord is going to threaten the serpentine as well.
