Suggested by Sonic Dante has super speed and high speed regeneration which are both really excellent abilities. He should be able to take a lot of the punishment that Accelerator can dish out but only for so long. Gradually his abilities will begin to weaken and that’s when Accelerator will really begin to have the upper hand here. His vectors is just such an absolute ability that Dante can’t hope to dodge it and Accelerator is fast in his own right so he could dodge Dante’s attacks long enough to win here. Accelerator wins.
