K I got an idea for Kai X clay (pheonixshipping) story that may never come alive.
Basically, it follows a similar approach to a fanfic I read on Wattpad, Kai hides and eavesdrops on his friends talking smack-bang about him and he leaves, but gets noticed by Zane, still leaving even after his name is called.
Kai goes out to try and sorta prove himself to the gang, he comes across a portal that is open, while contemplating if he wants to leave and abandon his duty as ninja of fire, monsters appear, Kai, not wanting the monsters to cross the portal into the other world, fights them off but as soon as he is pushed back by the monsters into the portal and on the other side, the portal closes and Kai soon gets captured by jester and the book guy (I haven't watched Nexo knights in who knows how long, shut up).
clays part, I'm not sure since I barely have a clue what's going on, probably clay having trouble coming to terms that stoneheart is his mother and therefore, he's magic, so he just practices hiding that fact and gets ready to go on a siege to jesters lair (where Kai is currently held captive).
Kai is constantly trying to attempt to get out via a hole in the roof, the problem is that his tired from jester and book thing trying to 'break' him, his leg is probably broken at this point and on the latest attempt, he managed to cut his hand on a rock in the wall. The Nexo knights come in and even tho Kai at first refuses the help, he is grateful for the help they stubbornly give him as they head back to base from the siege, with clay carrying Kai there due to his leg injuries.
Kai learns of the world he is in and gets to know the Nexo knights, and that's all I've got.
If I got any logic from any fandom wrong, pls correct me and have a nice time of day
