If you could be any super hero and/or have any super powers, who would you be and why? Would you use super abilities for good or evil?!

I won't be any hero in marvel or others, I only go for anime. If I can be a hero I will choose to be Tatsumi in Akame ga Kill. He have a katana which can transform to something like... I don't know how to describe, so I put a picture beside.

The reason why I want to be him is because he was so cool and a kinid person, he wanted to save everyone from greedy's Government, so he choose to fight. I also want to save those people who are in trouble, I know someone might afraid of me even I am a hero or savior. I will still try to hide my true form and survive alone. I don't want to have any partners, because they could be a trouble for me or a bad partner which have some weird personality. All I will do is just helping anyone I could, if I can't I will still take a try.

Thats all, thanks~
