You need to do the secret history missions to unlock Bardock and Future Gohan as masters.
You need to collect all the 5 Time Eggs from the Time Distortion Areas (Capsule, Guru, Majin, Freeza and Satan/Hercule) and use that 5 eggs to unlock the two special missions.
After completing the Bardock special mission, Bardock as mentor appears. Same as Future Gohan, after completing his special mission.

Bardock northwest of bamboo forrest, and Future Gohan is closest to Tien, by the lake/pond.

finish secret history missions first after that you unlock them
