I'll Protect You | Ninjago LavaShipping Fanf...
After months of training against him, Kai and the other ninja are faced against Lord Garmadon, who has now been transformed into a dragon by the Overlord.
Just before Lloyd defeats his possessed father, Kai is severely injured, which nearly costs him his life. He was, unknowingly, left on the battle field, slowly dying.
Luckily, the battle ends quickly and Cole finds the injured ninja trapped partially under some rubble.
His injuries must be treated quickly, or else the hotheaded Fire Ninja will be gone forever.
