is one piece episode 810 filler?

Big Mom's enraged army stops to face Luffy, who tells Nami and Kingbaum to run away. Nami reluctantly complies, and the enraged army is incredulous at Luffy's fighting ability in his current physical state.

However, Luffy does not pay any mind to their words and activates Gear 2, plowing through dozens of Chess Soldiers. Two Chess Soldiers manage to grab hold of Luffy and allow others to jump him, but Luffy repels them by inflating himself.
