PulseMan is the Titular Protagonist of said game.
Fanon Ideas so Far
PulseMan is somewhat similar to MegaMan in several ways:
1. Both their Names end with Man.
2. They also have some kind of love interest (MegaMan with Roll, and PulseMan with Beatrice.)
3. Both MegaMan, and PulseMan were spiritual Precursors of other franchises. (MegaMan for his subseries' and Mighty No. 9., and PulseMan for Pokémon and Drill Dozer (Yes, GAMEFREAK, the creators of Pokémon, also made Pulseman!))
