Without time to react , all of the ghosts are dissolved by Nya ' s water powers , except Morro , who battles and subdues Nya . Lloyd then confronts Morro , who crumbles the temple he is standing on apart and levitates its remains into the air . Lloyd is then forced to jump from debris to debris to the Realm Crystal . Using the Sword of Sanctuary and his element of Wind , Morro is able to keep Lloyd from getting to the Crystal . Before he can knock the Green Ninja off the temple ' s remains , Ronin arrives in R . E . X . , and bombards the debris with a shower of golden coins , causing the debris to plummet to the ground below as Lloyd enters the room with the Crystal . With Morro having disappeared , Lloyd obtains the Crystal and builds up his energy to destroy it - but Morro enters , and pleads for Lloyd to leave it be . Lloyd tells him that Morro had his chance , only for Morro to tell Lloyd that if he destroys the Crystal , he won ' t be able to see his father , who is still alive , ever again . Lloyd is rendered speechless and extremely uncertain by this , as Morro continues imploring him and the Ninja tell Lloyd to destroy the Crystal . Lloyd tells Morro that his father would do everything to save Ninjago , while Morro would do everything to destroy it . As Lloyd builds up his energy once more , the tentacles of the Preeminent emerge from the Cursed Realm and latch onto him , with one tentacle snatching the Realm Crystal and the rest pulling Lloyd into the Cursed Realm , seemingly defeating the Green Ninja .
