BlackWargreymon attack Oikwa

I'm starting to learn how to draw manga these past few days ,and this time the teacher give me an assignment which is "One page" manga, the condition is : when people read it,they will understand without reading the whole story ,i struggled a lot when thinking of story like that, since i'm a Digimon fans ,i just flashback all scene from Digimon Adventure~Xros Wars in my head,then i decided to draw from "Wargreymon vs BlackWargreymon" episode
This is a scene where Blackwargreymon met Oikawa for the 1st time,i twisted the story a little ,so it's slightly different from anime
