This is prolly going to be the last time I respond to yet another Glads/Nova thread. On second thought I'll just bookmark this so that I can cut and paste this response when this inevitably comes up again.
A significantly less powerful Nova fought Glads to a double tko before. And it was only a double KO then because Nova was drained from the discharge for plot reasons.
Currently Rider is significantly more powerful and more skilled with his power set as well. Glads is the same guy that he was when they fought 18 years ago. He punches things really hard and/or blasts things with heat vision, neither of which present a significant obstacle for Nova currently. So unless Glads has some new abilities that I don't know about I see no logical reason why the outcome of a fight between the two currently would result in anything other then a win for Nova.
