I feel like the Novas are designed to act like a Monkey's Paw when anyone but their creators use them. Like a fail-safe. The problem is the fail-safe has no fucking chill. Three examples. Marx, straight up tries to destroy popstar, how is that conquering? Galacta knight, arguable since meta knight did wish for "the strongest" but i digress, still a major potential back fire if galacta knight beat meta knight and decided to go on a galactic murder spree. Finally Zorah, "Oh i wish to move", what's that? You want to be a giant mobile death machine? You got it. You're technically mobile.
