Hunter x Hunter is a shonen series that serves up a successful formula for delivering comedic moments that add to the story without detracting from any intense or emotional interactions. In particular, the 1999 version of the anime contains a lot of fun, light-hearted scenes that allow the viewers to spend time with the characters and see firsthand the friendships they've forged.
9 Sweet Fight Alongside a very sweet reunion between the four main characters, there is a great deal of shenanigans. Upon seeing Kurapika at the park, Gon enthusiastically spits out some of his ice cream onto Killua, also dropping his cone on his friend's head in a rush to greet their friend. He is completely unaware of the war he just started with Killua, who interrupts Gon's meaningful conversation with Kurapika to shove some sweets into Gon's face.
6 The Treasure Trove Tonpa is up to his usual aggravating tricks when the Hunters-to-be are forced to scour for treasure in order to get room and board. After Gon makes a discovery that seems to be worth a fortune, Tonpa convinces him that there are better treasures further out. This prompts Gon to hand over the treasure and go off in search of more. Killua confronts Tonpa about his lies, but it turns out Tonpa had unintentionally led them to a bigger treasure trove.
3 Chocolate Robots This scene is worth mentioning for the shot of Killua's face alone. However, the overall scene where Gon finds out that Killua spent all of the money he'd just earned in Heavens Arena on chocolate is pretty humorous.
