Regi Giga is a male Regigigas that appears in Rumuadobencha. Regi is known for his incredibly short temper and aggressive nature. He first appeared as a vengeful monster seeking to destroy Doidle and anyone who stood in the way.
Doidle and Regi have had a history. Once while in elementary school, Doidle accidentally pushed Regi off a cliff to a layer of spikes. Regi got permanent scars and had spent years in the hospital. Once he got out, he went out to destroy the dog that destroyed his life. After almost fulfilling his goal, he got captured by the Vinyl Monsters and was almost sentenced to an unknown fate when Doidle came in and pleaded to let him go and that he was sorry. Regi felt a little better, and had since joined Doidle.

Regi is a main character. He originally was an antagonist, but he changed his ways.
Regi gets out of an hospital after Doidle accidentally pushed him off a cliff filled with extremely pointy spikes when both were in 1st Grade. After spending his entire young life in the hospital, he wanted to make Doidle pay for it. He tracks Doidle down and after some time of tracking him down, he finally found Doidle, but with company. Regi engages Doidle in battle, as Doidle pushes his friends aside so no one got hurt. But this was not the case, as Doidle's friends wanted to help, but each fell one by one. Before Regi could mortally wound Doidle, Godzilla comes to tell Regigigas that he had done too much; Badly wounding anyone protecting Doidle, thrashing through Toy Town, making a Lego spill and even beating up endangered species! Regigigas response was pushing the king of the monsters away, and he was going to finish what he wanted to do, but Godzilla says it is enough and ties his hands together. Godzilla then takes him to determine his judgement. But before the protectors of Bedroomia could say his fate, Doidle showed up and said that Regigigas is just upset, and Doidle says he is sorry. Regigigas feels better, but not that much. Doidle asks the Vinyl Monsters to let him free, and Regigigas is let free. But Regigigas states that he does not forgive Doidle completely, because of his lost childhood.
