He is in charge of the Megaranger program and chief of INET (International Network of Excel-Science and Technology), he marketed the Megaranger video game to find five candidates to be Megaranger.
Although Kubota had recruited the first of his five in Kenta Date, a student who had become a professional at the Megaranger video game and thus the perfect candidate for the project, a surprise attack forced him to give Digitizers to him and four other students investigating I.N.E.T. during the first attack of the Nejireiga on Earth. Guiding them to board the Mega Shuttle, the team escaped to the Mega Ship, which became his base of headquarters during the Nejireiga invasion. -
Kubota once was a scientist working alongside a Dr. Samejima on experiments regarding connections of Earth and other dimensions. The two worked on various projects associated with I.N.E.T., most notably a means to control energy for human usage. Initially they attempt a means of directly connecting humans to the energy, but the attempt leads to the test subject, Samejima's daughter, becoming killed in the process. After this failure, they started work on a special "strengthening suit" to be used for the utilization. When Samejima discovered a strange "twisted dimension", he obsessively completed research to travel to their on his own. Kubota tried to assist in helping him go through with the research, but Samejima ignored his hand in friendship to complete it on his own. Ultimately, the device the mad doctor invented teleported him away from Earth and to the dimension of Nejireiga, where he would become Dr. Hinelar, assistant of Electro-King Javious I on his invasion of Earth. Samejima would take the developed suits with to Nejiregia, forcing Kubota to start over in their development. Through the incident, Kubota learned a valuable lesson about the importance of teamwork and not doing anything dangerous on your own, a lesson he continues to try and push upon the Megaranger.
After the loss of Samejima and the suits previously created alongside him, Kubota went in a different direction in the development of the Megaranger. Alongside I.N.E.T., he developed first a "prototype" suit of a silver color before developing five new suits based upon the silver one. Although the intention was for the five suits being the actual suit, the sixth silver prototype was eventually stolen and utilized by the young I.N.E.T. developer Yuusaku Hayakawa, who made his own adjustments to make the "MegaSilver" suit suitable for combat.
Although obsessed in research and making sure that the Nejireiga don't invade and conquer Earth, Kubota does have a connection with the five Moroboshi High teenagers who became his Megaranger and trusts them on the work needed to complete their mission. When another I.N.E.T. scientist tries to replace the Megaranger's control of Galaxy Mega with an automated program to fight the Nejire Beasts, Kubota tried to vouch for the Megaranger's combat skills and unpredictability, but was ignored until the latest Nejire Beast proved too much for the simulation program, thus following alongside the scientist's own words in letting the kids handle the mech.
