To deliver the seasonal new transformation.

Goku is retarded, no, is not a joke post, SSY3 is an useless form that just consume all your stamina in a single moment, it would be a good idea for an attack, but not for a base form, even in the same Buu saga the SSY3 got prove to be useless.

Pandering to spics with aryan envy

Pretty much an evolved form of that form with the huge muscles that wastes a shitload of stamina
