Is Blade vulnerable to nerve/tear gas? I don't know enough about his strengths and weaknesses. Batman is peak human, Blade a little bit stronger, faster, more agile, probably has more endurance as well.
That gives him a slight edge. But Batman has taken down guys stronger and tougher before.
As stated previously, comics Batman is very powerful. But Blade can neutralise most of his toys, I'm just not sure about the nerve/tear gas.
Voting is difficult, but for now, until I hear evidence to the contrary, I will vote Batman takes it
