In this form, the user's appearance changes dramatically, gaining a massive increase in strength and muscle mass.
Usage and power
In this state, Master Roshi is at his full power, and can perform many of his techniques at their full potential, most notably his MAX Power Kamehameha. While its full power is unknown, Roshi was able to easily destroy the moon, while the likes of even King Piccolo could only destroy a city. During the original Dragon Ball, however, the form is deeply flawed; Roshi's movement speed is slowed to the extent that he barely moves when in the form and using an energy attack while in this form will waste all of his energy.
When Roshi uses the form once more in Dragon Ball Z: Resurrection ‘F’, he seems to have better control over it, being more mobile and being able to use more than one energy attack.
During the Tournament of Power in Dragon Ball Super, Roshi uses this against Jium from Team Universe 10. In this state, he was able to use his MAX Power Kamehameha to make Jium fall out of the stage. Later, he uses it against Ganos from Team Universe 4 and pushed himself beyond his limits, which was powerful enough to knock Ganos in his Avian form out of the ring. However, Roshi used up a lot of life force using the attack, leaving him in a near dead state until he was revived by Super Saiyan Blue Goku.
In Dragon Ball Super, during the preparation for the Tournament of Power, Roshi falls under the spell of Yurin, a jealous old friend of Tien. Under her witchcraft spell Master Roshi no longer held back his power and fought with 100% power. At maximum power he was able to quite easily overpower and would have killed Tien had Goku not saved him and briefly held his own against Goku's base form but was in the end quite easily beaten by Goku's Kamehameha after he put up no defense because he received no commands from Yurin. Goku said that Roshi has been doing a lot of training in secret and is quite shocked at what he is capable of when he is actually serious and not holding back.
Roshi assumes this form in an attempt to fight Broly, but ultimately backed out at the last minute, being too drunk to focus.
Roshi uses this form to fight Frieza's army, managing to hold his own and defeat several of them.
