The father of Bulma, Dr. Briefs is an elderly, brilliant and eccentric scientist. He is one of the smartest men in the world. Dr. Briefs is the founder of Capsule Corporation and the man responsible for the invention of the Hoi-Poi Capsules, which can shrink inanimate objects down to pocket sized capsule of namesake. He is easy-going and friendly. Dr. Briefs rarely leaves his home, even if he knows he'll die (in the Buu Saga, he and his wife refuse to leave their pets even after Capsule Corp. has been specifically targeted for destruction; they know they can always be wished back) and he can often be found tinkering on a number of complicated gadgets while surrounded by his beloved pets. His favorite pet is a small black cat, named "Tama" in the original anime and "Scratch" in the FUNimation dub.
