pretty sure Deathstroke gives nightwing regular props on his fighting skill saying he is almost as good as bats if not better then him..
he has laughed at arsenal and told him only one that can give him a challenge is dick and whatnot...
dick is pretty skilled as well good enough to be top ten and above black canary seeing as he has single handedly faced off against cassie on top of a giant penny... and he has done better in certain h2h fighting then bats with the same opponent bruce has faced due to his style of fighting in which bats would have bn trounced..
dont you disrespect my Dick... you can talk trash about DS and bats all you want but you watch your mouth when it comes to my boy.
