Prof. Tatsumi inside the control room of Bay Area 55

Years before, he predicted the invasion of the Psyma Family  but no one believed him. Forced into exile and ridiculed by the elite scientific community, he secretly developed the GoGo-V technology.

He at one time he was rival with his children's superior, Kenji Inui. The two tried to out do each other in everything from job assignments to women and sports. They even fought over who would lead the Rescue Task Force, causing chaos until was decided that Doctor Tatsumi would give the orders. Doctor Tatsumi has also built an undersea base in the bay which has all kinds of weapons and mecha for the team to use, known as BayArea55.

To save the earth and the human race from threat only he knew of, he pays the heavy price of losing his family. Years later, he has to convince his children, , who are embittred when they find the father whom they believed dead alive and well, to join his cause. Naturally, they find it difficult to forgive him for leaving them and their mother, even if it was to save the world. despite everything he still loved his family, and tried to prove it once by using a prototype Anti-Hazard suit to save his children from the Psyma Family.

In the finale, Mondo was thought to have been killed alongside his rival when BayArea55 sank beneath the sea from the massive floods caused by Grandiene, but both men had survived and Mondo now lives happily with his family. However, Mondo briefly went out of retirement to prepare the GoGo-V equipment, when he detected Pierre's minus energy. Mondo was instrumental in working with the TimeRangers robotic assistant Navigation Robo Tac, in bringing both teams back to the present when they were transported across time due to Pierre's magic as well as bringing the GoGo Five's mecha from the past to the present with the TimeRanger's time travel technology, to help destroy PierreBori.
