I've always been fascinated by swords and swords(wo)men, like how they can pull that bloody long sword out from the scabbard carried on the back in one swipe in uber-cool ninja style without getting stuck or how their blades can be so sharp it cuts everything in one swipe as well..
And since I've watched/currently watching a few animes (namely One Piece and Hitman Reborn) that has sword wielders claiming (either self-proclaimed or nominated doesnt matter)that they are the best in the world, I'm kind of trying to put them all in one battle of the ultimate. HAHA!
*Bleaches do not count! WAHAHA!!
*And pictures are from various sites around the web..
Candidate #1: Roronoa Zoro - One Piece

What happened to the scar!?!
The 2nd man of Straw Hat Pirates, who uses Santoryu, i.e. wields 3 katanas, 1 in the mouth and 1 on each hand, and who either naps or does crazy weight trainings (or both together) during his free time, so even without his katanas, he is still able to unroot and throw BUILDINGS at opponents.
Due to his pact with his late childhood fren Kuina, Zoro trains to be the strongest swordsman in One Piece World. He views defeating Mihawk as his goal to be the strongest after the defeat which left him that long scar across his chest as a constant reminder.
Skills
- Asura (gives out the aura to opponent that Zoro has 3 heads and 9 swords)
- x Pound Cannon (x bcos the number varies per his strength)
- Other Onigiri sounding skills that he names on the spot

Meitou; Wado Ichimonji, Sandai Kitetsu, Meitou; Shuusui

Santoryu
Candidate #2: Juracule Mihawk - One Piece

Hailed as the swordsman above all the world's swordsmen, and being a member of the Shichibukai, Mihawk wanders around the seas on his own in a small raft and takes on pirates at his own whim.
He encounters Zoro at Baratie and humilated him by using only his sword-shaped pendant to take on Zoro's Santoryu. After his victory, and with Zoro attempting to give up his life upon defeat, he used his Kokutou Yoru, the strongest sworld in the world, to give Zoro a massive slash across his chest as a sign of acknowledgement of Zoro's strength and determination; leaving Zoro a challenge to win him.

Candidate #3: Takeshi Yamamoto (Present version) - Katekyo Hitman Reborn

A baseball buff in Hitman Reborn who thinks lightly of everything and was mafia-ized by Reborn/Tsuna. He inherited 8 forms of Shigure Souen Ryu and Shigure Kintoki (a bamboo sword which becomes a katana when used with Shigure Souen Ryu) from his dad before the Varia arc and goes on to create 3 new forms taking ideas from Squalo's attacks.
Although the Ten-Year-Later version share the title of the Sword Emperor with Squalo, I think the present version will be stronger, having had special trainings from Squalo before the Choice arc and being able to infuse the Rain flames into Shigure Souen.
He's cute. Mwahahha!!
Candidate #4: Superbia Squalo - Katekyo Hitman Reborn

The loud, second-in-command assassin of the Varia, who cut off his own left hand and replace it with a sword to understand how the previous Sword Emperor feels.
He thinks highly of Yamamoto, like how Mihawk thinks highly of Zoro, and compiled 101 of his battle victories into a DVD set for Yamamoto to study. His attacks, which are all named in Italian (Attacco Di Squalo, Zanna Di Squalo, Scontro Di Squalo), features the aggressiveness of the shark extensively.

Ahh.. Soooo many!! But seriously, it will be interesting to see who will win the battle of strength (Zoro/Mihawk) vs tactics (Yamamoto/Squalo) thou I doubt it will NEVER happen.
Oh well, unless there's a collaboration between Oda-san and Akira-san.
