Kuwabara's victory over Elder Toguro, probably the most monstrous bad guy in the series up to that point. Anyone who says that Kuwabara is any lesser a badass than the rest of the team can SUCK IT.
Kuwabara: "SPIRIT FLYSWATTER!"
Elder Toguro: *squashed into pudding*
- "You have no soul... You're just a nasty little waste of space! NOW, DIIIIIEEEEE!!!"
- Made even better by how almost nobody In-Universe, not even his own teammates, thought he'd survive.
"Always expecting nothin outta me. Just makes for a better surprise..."
