User blog comment:MrPacheco101/Round 10: Blackheart vs. Simon/@comment-2016768-20110419222724

My vote is for Blackheart. He can basically manipulate himself or others around him to the size, shape, and form he wants only by willing it to happen. That, and the fact that his powers are darker than Simon's means that he'll exert even more force and powe rfrom his attacks than Simon will.

Blackheat will win with around 600 kills to his credit in a semi-close battle.
