Dragon Ball Z, Vol. 19: Death of a Warrior (Dragon Ball Z, #19) | 
pick10/10:
Genuinely one of my favorites in all of Dragon Ball so far. There‘s so much emotion and power unleashed as a result of those emotions that I can‘t help but to feel them alongside the characters.
The death of Goku and Gohan reaching his full potential was awesome, but I particularly like how Gohan held strong no matter what. Not only did he choose to comfort his mother, but he knows he can reach Piccolo whenever he needs a father figure.
