ok so I realized that no one following me will get the context of his yelling here, so I am explain:
Shadowmaru is one of the cooler cats among the BP team, being a ninja spy kinda dude. But he’s based off the G1 Transformers Sixshot toy mold, so he turns into… well, 6 different things. One of those things happens to be an animal that he calls a wolf, but really just looks like a big purple robot dog at best. Everyone always mistakes it for something else, and in this scene, Yuuta (the ”Miniboss”) ends up calling it a cat or something.
Moral of the story: Shadowmaru gets uppity when no one knows hE’S A BADASS WOLF, OK, HOW MANY TIMES DOES HE HAVE TO TELL YOU OHMYGOD
