Full body view of Dr. Gamma.

Dr. Gamma is an elderly man with a hunched back, a long nose and dark grey neck length hair that flares out at the sides and that has gone half silver; the right side of his hair and beard are silver, while the left side of his hair and his mustache are still dark grey. He wears a labcoat buttoned over a white collared shirt, a brick-colored tie emblazoned with the Goha Enterprises label, grey pants, and unusually for a laboratory worker, open-toed brown sandals.


Gamma, Delta and Zeta were conducting an experiment in the Gohanium Section when returning employee Mimi Imimi arrived, though they didn't answer her query as to her job in the section. They received an email from Gavin Sogetsu explaining that Romin Kassidy's Dragias Curry and Prima Guitarna Curry could produce an explosion strong enough to destroy the Goha Enterprises Main Office, and decided to see if they could use it for their experiments. When Romin confronted Mimi over not eating her curry and the Chef Drones agreed to let them Rush Duel over it, Gamma was quick to assure them they had the perfect place to Duel and Delta offered their Explosive-Proof Laboratory. Gavin arrived with new employees Yuga Ohdo and Lucidien "Luke" Kallister to watch the Rush Duel, fearful of the prospect, though Gamma assured him the glass they were behind was super-reinforced. During the Rush Duel, a droplet of the two curries mixed and detonated, blowing out the reinforced glass of the laboratory, much to the joy of Gamma, Delta and Zeta. Romin eventually defeated Mimi, so Gamma, Delta and Zeta eagerly took all the curry to experiment on, Gamma warning his co-workers to be careful with the curry and admitting the energy they could produce was exciting. However they were interrupted by a starving Luke, who dived towards the pots and combined them, producing an explosion that devastated the lab.[1]

Gamma, Delta and Zeta later had Mimi assist them with a kinetic energy experiment, observing her performance as she rode an exercise bike and waving to Luke, Swirly, Masahiko, Toshihiko and Mimi's son Yosh when they visited.[2]
