Story

Dr. Brief is the president of Capsule Corporation, one of the largest companies in the world. In addition, he's the genius scientist responsible for inventing the revolutionary Hoipoi Capsules that can compress any manner of object so you can carry it in the palm of your hand.
A lover of all living creatures, he takes care of abandoned dogs, cats, and even dinosaurs he's gathered over the years on the Capsule Corporation’s sizable grounds.
​

(Tale 69)

As a child, Goku visited the Capsule Corporation to have Bulma fix the Dragon Radar, leading to Dr. Brief at first confusing him for the security guard who had led him there.
"Are you sure you’re only 12?" he asked the guard, perhaps playing dumb.

(From Part 69)

For her hunt with Goku for the Dragon Balls, Brief once mistakenly gave Bulma a capsule case holding some of his preferred reading material, which almost caused her to be attacked by the Red Ribbon Army.

(Tale 69)

The doctor also took the spherical spaceship that Goku came to Earth in as a baby and remodeled it into the ship our hero used to reach Planet Namek in just six days. Expertly crafted with an internal artificial gravity engine that reached up to 100 times Earth’s gravity, not to mention amenities like a full bathroom, kitchen, and bedroom, in the end what tripped Dr. Brief up was where to put the stereo speakers. Thanks to this ship, Goku was able to immerse himself in training while travelling to Namek.

(Tale 251)

And when the Androids attacked, he made a gravity engine that could reach 300 times Earth’s gravity at the request of Vegeta.

(Tale 336)

Dr. Brief was also able to assist in finding the Androids' weak points by analyzing the schematics that Krillin procured from Dr. Gero's Laboratory. But there were many things that even he was unable to grasp, leading him to lament the waste in potential. "If only Dr. Gero had used his genius for good…"
