@yababegrabb6:
Sentoumaru sucks. He has done nothing why would you vote for him?
My reasons for liking him, in no particular order:
1. Character design based on awesome Japanese folklore hero
2. Captain of the Marines' Science Unit and personal bodyguard to THE Dr. Vegapunk
3. Commands Pacifista army
4. Wields a massive broadaxe
5. Completely overwhelmed Luffy with no weapon and no Devil Fruit
6. Scolded an Admiral
7. Secure enough to wear a bib
As opposed to Basco Shot, who:
1. Has stood there
2. Took a swig of alcohol
3. Got pwned by Sengoku
4. Helped throw a blanket over Blackbeard
5. Shot a dying old man
6. Is horribly, unutterably creepy to look at
Does this answer your question?
