Oh yeah. Well that was only one moment though when he was truly evil. Since you stopped watching I may as well spoil it for you, his son turns him back to good, and then the evil spirit goes to a computer and runs a virus. Then this is where the next season starts.
The seasons from there get much better than the first ones but sorta go into a line of overpowered ninja vs enimies. In the end of season 3 (where the evil spirit takes over this futuristic sci-fi ninjago) Zane beats the guy with his over powered ice stuff.
In season four there’s this island and stuff with snakes and people turning into snakes happens. Garmadon sacrifices his life to save the day.
Yeah, also don’t watch season 5. This is where evil spirits and stuff go everywhere. There’s this ghost dimension where all the ghosts roam about and some of them are let free, then Lloyd gets possessed by one of them and stuff happens.
Season 6 is my favorite, there’s this jean thing where he can grant wishes. There’s also more pirates too who help him. In the end he actually ends up winning (this is why I love it.) but Jay uses his last wish to convert everything back to normal.
lol, for once the bad guys win.
Season 7 goes back to the old gain all the weapons to win thing. There’s these time weapons and weird stuff happens. Basically it set the standard for a reset in ninjago
Season 8 is after the reset and when the movie was released. There are the Oni Masks and the ninja have to get all three. They fail and the bad guys win in getting Garmadon (the evil side) back.
Season 9 I haven’t finished yet.
So there’s that, some stuff on all season on Ninjago.
There’s also this video game where a guy named Ronan takes the memories of the ninja, then they try to retrieve them back. It follows through from season 4-5 so watch a bit of gameplay on that so you understand where Ronan came from.
