I say Batman takes this as he is a thinking man's fighter. Taskmaster has all the moves but I don't believe he can out wit the World's Greatest Detective. That is what would give Batman the edge in the the final outcome.
Flashpoint changed everything. No matter how much anyone says there's no reboot, it truly is. Some of the stories are good ones, even if continuity is ignored. The idea is to get everyone talking and buying and it has. Money speaks. If it is not successful then things will change.....again.
They done messed me up with this one. Wow. I only take the editors to task when they specifically said that they were not making a new continuity but with the events of Flashpoint, anything goes so there should be no reason to be mad.
