As mundane as it may seem, for many English fans, finally being able to hear Goku's surname in the dub certainly qualifies as a CMOA, especially given the context. And for bonus points, Sean Schemmel was the one who lobbied for it to happen in the first place.
I AM THE SUPER SAIYAN, SON GOKU!!!.
The Ginyu Force's entrance.
Ginyu Force Rules! Ginyu Force Rules! Ginyu Force Rules! Ginyu Force Rules!
Just after his SSJ3 fight against Majin Buu, Goku gives this parting line to Babidi:
Oh, and Babidi? When you get to Hell - and you will sooner or later - King Yemma will make you suffer."
The dub, in general, being more accurate to the original Japanese with better voice acting to boot. It's vindicated FUNimation further as a competent dubbing company, including the (explosive) usage of Son Goku's surname for the first time, and gave fans who don't care for Z's dub a great one to watch.
The original Dragon Ball Z was a well-loved icon on Cartoon Network's Toonami block, with the Ocean dub managing to find its ground on the block after a failed syndication run, bringing in some of the highest ratings the network has ever seen, and convincing Funimation to continue the english dub in-house. Fast forward to 2014, a couple years after Toonami was officially revived as a Saturday night block on [adult swim], and the production crew has confirmed that, following in the footsteps of the original, Dragon Ball Z Kai would officially be airing in Fall.
On August 8, 2015, the airing of Kai on Toonami pulled down over 2 million viewers. It became the first show in the history of the relaunched block to do that!
