I admit, I'm personally fond of the Hitsugaya vs PSP-kid fight. Mostly because the latter starts ranting about his motives and tragic backstory, and Hitsugaya just uses the opportunity to appear behind him and nearly stab him in the back.
Yeah, thats one of the reasons for why he is one of my favorite Captains, that and when he tried to kill an opponent before he had finished his powerup transformation.
