is one piece episode 798 filler?

The homies run away from Cracker and Luffy in order to avoid getting in their crossfire, but they are hit by Cracker's powerful aura and wither away. Luffy makes the first move as he activates Gear 2 and rushes at Cracker, but Cracker easily blocks Luffy's attacks with his sword and shield.

Cracker then attacks, and to Luffy's shock he finds that Cracker has suddenly gained extra limbs and swords. Cracker attacks Luffy with three of his swords, sending him flying into a tree homie close to Nami and Pound.

Cracker approaches the trio now with four arms each holding a sword, shocking Nami.
