I like the ambition of the Voltron battles being unconstrained by conventional physics but it's dangerous ground for a progression fiction to tread. The interactions are so unconstrained that it bounces between sounding like two coppers fighting and random bullshit. Like, "Then she threw a rock at him and, and, every dude on a distant planet nutted in his pants. Then he threw a kick and a bunch of stars blew up. Then she called upon her ultimate power and the next chapter got deleted." Which is fine, I like ambitious writing and am enjoying the progression from mundane to metaphysical.
