My favorite fight is from Volume 1, Chapter 8: Players and Pieces. It was the first time we got to see JNPR and RWBY working together to stop two giant Grimm. Characters fly all over, Jaune pulls his weight in JNPR against the Deathstalker, and the plan RWBY uses to kill the Nevermore still delivers pumping adrenaline and thrills every time especially with Red Like Roses II enhancing the epicness.
