User blog comment:JWarrior89/The Battle of the Criminally Insane: The Joker vs Professor Genki/@comment-5900266-20130130221838

My vote:

Melee: The crowbar has that blunt trauma and the penetrator does too. I don't know where to give an edge: EVEN

Close Range: The BANG! Revolver has that element of surprise and the other revolver is pretty similar to Genkis one gun: JOKER

Mid Range: The Thompson is useful in the hands of a soldier. I know Joker has a lot of experience, but he and his men just spray and pray: GENKI (Does he spray and pray too?)

Long Range: The TAR-21 failed to kill Batman in one shot and Genki has greater accuracy: GENKI

Explosives: An RPG beats things you have to place: GENKI

Special: A gas bomb is unreliable for if the wind blows the other direction or you get caught in the blast, it is useless: GENKI

WINNER:

Despite all these edges I believe Joker will win due to the fact that he terroized Gotham and every time he gets put in prison he escapes.

P.S. I like the brother idea!
