Raptor (Nightwing Volume 4 #30)
The last time we saw Raptor, he kidnapped Bruce Wayne and dueled Nightwing in a scrapyard. Raptor lost and even had his arm snapped in half by an enraged Nightwing before being arrested by Spyral.
And Nightwing’s calling Raptor his mentor? They were paired together in just 8 issues!
