Its not related to manga, but I think it's quite an intresting episode, and I didn't find anything related on forum. Sorry if there already exist a thread about it.
Anyway this is the best link I could find with english subs, enjoy:
Coby is so awesome
Gay voice but still very powerfull, I actually can see him as a leader of marines now
Finally got around to seeing it and to say the least it was very interesting, especially Coby who I now look forward to seeing within canon.
I have to say I was impressed that they at least TRIED to make the antagonist not be a complete OHKO villan and the whole trapiese thing was pretty impressive honestly, didn't expect that from a filler special. *now waits for other posters to question sanity* I don't really get how Luffy could use a elephant gatling with one arm in a position like that but...eh, still awesome.
Zoro Vs. Mega Canon = ZORO WINS
