Nezi and Goku in “Unfinished Business”

Using you ignorant humans to help him gather the Dragon Ball was his plan all along.

Is that so? Well, he just lost some good friends. And as for you three, you're heading straight for the scrap yard.

Somebody shut his insolent mouth! (Goku is electrocuted) That will teach you the proper respect!

Trunks believed in him! They were friends! Pan too! They both really liked Giru and Giru truly likes them. I don't understand!

Heh heh heh. Sentimental fool. T-20-0-6 isn't even capable of such silly affection. Friendship, trust...what can these things mean to a mutant robot strictly programmed to do his duty?
