You are ARIN and in this story he has recently discovered he does have an elemental power, being spinjitsu, explaining his special abilities like object spinjitsu. All the other ninjas are here. Lloyd is helping you train in the monastery.

This isn’t normal avengers I made my own these are the characters yes there is a multiverse Leo- similar powers to Wanda but green and he prefers to create weapons. Oliver- god of fire and chaos, a bit angry sometimes but mostly means well Kai- he is a mutant and has poison powers and can create tentacles out his back. Charlie- he is from the how to train your dragon world, his dragon is called charcoal and it is a nightlight. (If you don’t know what that is search it up) Story: They defeat some aliens and you fall out the portal in the sky, Charlie and charcoal catch you. Continue. You are whoever you want.
