is one piece episode 285 filler?

Rocketman crashes into the front wall of the Tower of Justice. Spandam orders Rob Lucci to accompany him and Robin to the Gates of Justice, and tells the rest of CP9 to destroy the Straw Hat Pirates.

He summons Funkfreed, and the elephant morphs into a sword. He tells Robin that the sword was imbued with the power of the Zou Zou no Mi Devil Fruit.

Franky makes it to the remains of Rocketman and pulls out Kokoro, Chimney and Gonbe. Although he frets over them a moment, they awaken with only nosebleeds for injuries.
