You went through a portal of darkness and appeared on the tallest building in the city of Vale and the streets were filed with people being happy and you smirked and placed your hand on the roof making heartless go all around the city scaring people making them feel fear which attracted Grimm and you smirked as you were creating the chaos and it started to rain making it darker out in the night and the Hunters and Huntresses started to appear and a certain pair from beacon showed up.(Y/n): Team RWBY...!? and Team JNPR...
They were killing Grimm and trying to get rid of heartless but they were struggling
Ruby: There's too many
Weiss: We need back up
Jaune: We won't be enough to kill them. AH!
He tensed up and Ren killed the Grimm that was going to attack him
Blake: What are we going to do
Yang: Where did these creatures even come from?!
Pyrrha: Look up there
They all looked and saw you stand up there
(Y/n): Well time for a reunion
You turned your back to them and fell back off the building falling towards them. Both the teams realized the heartless weren't attacking and there were no more Grimm in that area. You flipped and landed making the ground shake and the thunder roared in the sky when you landed.
Ruby: Are you the cause of these monsters
(Y/n): ...
Jaune: Who are you?
Weiss: What do you want huh?
Blake: Why are you torturing these innocent people, What are you gaining from this?
(Y/n): ...I'm going to enjoy beating you all..
Yang: You don't even know us
(Y/n) conjured two keyblades and Ruby gasped recognizing they were (Y/n)'s
Ruby: What have you done to (Y/n)?! Where's my best friend, What have you done to him?!
The lightning struck in the air making half of your face appear and your eye changed from your normal eye color to yellow
