Both wealthy playboys types by day, vigilantes (servants of the people) by night. (No superpowers) self-made, dedicated and trained to peak agility, skill and mastery of body and weapons of their time. Both channeling their personal small cunning dark nocturnal animal as totem, dress in black, masks, gloves and cape etc. belts full of gear, leave a recognizable symbol/mark as omen, have secret lairs/caves, where they keep their fast dark rides, etc...
And in some canon even helped inspire the other...
Although tragic, Zorro actually showed him that he can survive, re-purpose, "own" the darkness, and reinvent himself, as a masked creature of the night to fight back!.
He even still shares it and watches with his family- https://i.imgur.com/KVYsIqC.jpg?1
If they met, they would get along famously.
