Belligerent Sexual Tension/Western Animation

• The Adventures of Jimmy Neutron: Boy Genius has this between the title character, an Insufferable Genius, and Cindy who keeps trying to one-up him with varying degrees of success in the individual episodes.
• Ben and Kai in Ben 10: Omniverse. Rook even calls it "romantic bantering."
• Stewie and Olivia in Family Guy, made worse by their ignorance of what these feelings are. Though sometimes, it veers into genuine hatred.
• Despite Dipper's Precocious Crush on Wendy in Gravity Falls, he often comfortably slides into this dynamic with Pacifica.
• Perhaps the most famous example of this in Western Animation is in Hey Arnold. Helga is the Tsundere and Arnold, nowhere near a jerk, was at least hostile (or at least as hostile as someone like him could be), towards her.
• The first season of The Legend of Korra featured this between Korra and Mako but the "Belligerent" part won out by Season 2 and they proved to be Better as Friends.
• Obi-Wan Kenobi and Duchess Satine in Star Wars: The Clone Wars.
• There are quite a few examples of this trope in Total Drama including:
  • Duncan and Courtney in Island claim they hate each other, Courtney being an uptight Type-A and Duncan being a typical bad boy, but their tension is obvious to everyone but them, having flirty/hating banter
  • Heather and Alejandro in World Tour. Both have met their manipulative match and sparks are flying.
  • Stephanie and Ryan from the Spin-Off Total Drama Presents: The Ridonculous Race are this when their break-up is ending and they're close to reigniting their relationship. They still yell, snark and belittle each other but a few compliments and double entendres slip in as well, signifying this.
• Before it evolved into Dating Catwoman (or at least Flirting with Catwoman), Elita-1 had light overtones of this in Transformers Animated with respect to Optimus. It was overt with Sentinel.
• Jim and Claire in Trollhunters. They bicker until day's end, but there's never any doubt about how much they love each other.
• There's a memorable moment in Voltron: Legendary Defender where Commander Sam Holt opines that his daughter Pidge and her teammate Hunk have this... with Sam noting that he and his wife / Pidge's mother Colleen did have this in their youth.
• Wally and Artemis in Young Justice. Robin hangs a glorious lampshade on it in "Bereft."
