Z. When Vegeta powered up to his maximum to fight Goku for the first time, Launch was in a bar getting wasted and the ground started shaking. She went outside and saw birds fleeing and said it was freaky. Last time we saw her.
We see her lending energy to the Spirit Bomb against Kid Buu too, though that's anime-only.
Also, according to extra materials:
Quote:
After the end of the Kid Buu saga, Launch finds Tien Shinhan once again; she fell in love with him at first sight and had been constantly pursuing his whereabouts. He even reluctantly lives together with her, but she is not cut out for farming and Tien has no interest in romance, so she leaves after just a few days. After that, Launch apparently drops in from time to time. Though Tien gave her the cold shoulder, she still tenaciously persisted and eventually she and Tien got together as she wanted.
