YMMV / One Operation Joker

• Unexpected Character: Jonny Frost. The first time he appeared was in Joker written fifteen years ago and even then, it was a story set in an alternate continuity and not the mainstream DC timeline. Since then, he hasn't really made major waves aside from a blink-and-you'll-miss-it role in Suicide Squad (2016). Due to not being upgraded at all to a regular character in the main DC continuity and not being too memorable or able to stand out much during those rare times he does appear in other media, it can be surprising to see Jonny show up in this continuity and get a second go as Joker's henchman who advises him on taking care of Baby Bruce.
