WARNING: The following contains spoilers for Harley Quinn Season 2, now streaming on DC Universe.
As much as Harley Quinn fans loved seeing her and Poison Ivy finally become a couple and ride off into the sunset, it did hurt to know the innocent, earnest Kite Man got his heart broken. He was nothing short of selfless towards Ivy, not to mention he was fully in love. Plus, he even helped out Harley's crew on a few occasions, so he felt like one of the gang.
It felt so bittersweet seeing him say, "Hell No!" to getting married, but as he flew off, it offered a big opportunity for the show's writers. That's because given that he knows Harley's crew inside out, as well as knowing Harley's biggest weakness, Ivy, intimately, Kite Man should become Season 3's big antagonist if Season 3 happens.
Many would expect Kite Man to do the usual: mope, drink, eat tons of junk food and be a goofball loser who feels sorry for himself, but turning him into a villain would break the mold and give him more agency. It's fresh, unpredictable and fans would get to explore a whole new dimension to the character that even the comics have barely grazed. Kite Man could partner with Joker or Riddler a la The War of Jokes and Riddles comic arc, or he could gather his own team of B or C-list villains. An angry Kite Man could also show viewers the mastermind side of him with what he already knows about Harley and Ivy.
Furthermore, the way Clayface and King Shark embraced him, Kite Man going after them would add an emotional heft to the show, similar to how Dr. Psycho's betrayal did for Season 2. Psycho going after them hit hard as they were like family, so following a similar path with Kite Man should have the same effect, but it'd be more personal and intimate given what he and Ivy shared.
Honestly, audiences don't want him to become a toxic person, especially given his character in Season 1 and 2, but viewers can understand him wanting revenge. Aside from the pain of his almost marriage, he could want to focus on his own criminal career, trying to make a name for himself and earn the Bat's respect. He might even ascribe to become an A-list villain to impress his peers, proving Ivy and Harley wrong for underappreciating him. He's not short on imagination, so levelling up mentally and upgrading his Kite-arsenal could bring that personality shift that'll make the character more of a threat.
Kite Man could also do a 180 attempt to become a hero who brings down the villains, including Harley, Ivy and the crew. A wannabe vigilante would make for great interactions with the Bat and Gordon, and seeing as the show focuses on Harley's crew as protagonists, technically Kite Man would be an antagonist if he went down a heroic path.
Either way, he needs to be something more than just a running gag. Going after his abusive parents could be the first step into his descent into madness, and it would revive a man who's lost everyone he holds dear. Kite Man deserves better, and a third season can give him just that, even if it causes chaos along the way.
