Alucard has some really good regenerative abilities at his disposal, but I don’t think that it will be enough to stop Cooler. Cooler can destroy whole planets on a whim and his speed was so great that he was able to keep up with Goku’s instant transmission. That’s no small feat and Cooler is a lot stronger than he is given credit for. Alucard is simply doomed in this match. Cooler wins.
