is one piece episode 465 filler?

Little Oars Jr. is impaled by Gecko Moria and tries to save Ace with the last of his strength but soon collapses destroying everything at the bay with his enormous body, greatly shocking everybody with his defeat. Giant Vice Admiral Lonz tries to kill Whitebeard but he soon disposes of the vice admiral with his Devil-Fruit's powers easily.

Whitebeard then orders his crew to climb Little Oars' body and advance, to which they quickly climb breaking through any Marine in their way.
