Jack Haly

Jack Haly is the owner of Haly's Circus.

Early life
Haly owned the circus, but he also performed as the ringmaster. He loved all the performers and considered them family, and to young Dick Grayson, he was the closest thing to a grandfather.

When crime boss Zucco tried to extort money from Haly, he refused as he ran an honest business, but it would cost him dearly. Zucco sabotaged the trapeze rig of the Flying Graysons, killing four and paralyzing one.
