Hello Everyone. I’ve recently came up with an explanation of the changes in ninjago season 8 like the new looks for the ninja or the disappearance of old powers.
So basically in episode 74 Lloyd said that the reversal blade is too powerfull an they have to get rid of it. I conclude that the ninja destroyed the blade using their powers but the blade partly striped them of their elemental powers because it was made out of chrono steel and as we know chrono steel " is the only known metal that can absorb a single Elemental power of a living being" being overloaded with to many powers it broke and the shockwave made the ninja look younger (because it is the REVERSAL blade). I also provided very badly animated presentation gif. What do you think about all that ?
