It's just...this mask itches...- Czonka, Robin #4
Real name: Czonka
Other aliases: Headbanger
Kidnapped Steph and later Tim in Robin #43-#44. He was going to leave them to die in a building slated for demolition, but ended up hitting his head on a pipe and passing out so he was trapped with them. Tim broke his thumb to escape from the cuffs (a trick Steph apparently later used in War Games). He untied Steph and together with Czonk, they escaped. Czonk was so excited with this, he suggested Steph, Tim and him should be a team. Spoiler and Robin responded by punching him in the face together.
