Batman is back and he wins this match easy. Alien may be pretty quick, but he lacks the power that Batman has. Batman is a being of pure power and takes down everyone in his way. Alien just can’t compete with Batman’s plans. Batman also has the power of Super Strength and rises up the ranks. Batman wins.

I’d still go with Batman here. A few good gadgets will be enough to take the Alien down for the count.
