I present to you Gohan's strongest and newest form, so powerful that he can shatter entire dimensions and omniverses by his awesome CHAD aura alone, so strong that not even El Grande Hermano or El Tio can match it, so strong that no fusion of Shaggy can even hope to stand in his presence:>Gohan Gris (Gray)
By using Hair Regrowth formula he cancels Super Saiyan Calvo and the power of Super Saiyan Blanco becomes Super Saiyan Gris. It turns out that this entire time Gohan was treating his balding, but used the power granted by Calvo as a stepping stone to ascend even further beyond. First you must go completely bald, then you regrow your hair, and your power is limitlessly and exponentially multiplied beyond imagination.
Gohan Gris is the ultimate, most perfect form in all of DBS. Super Saiyan Gris is impossible to defeat and is only attainable by Gohan because he is the only character with an Ultimate ("Mystic") form. This is what he meant when he told his father that he would acheive a form through a different method. By balancing both Blanco Ki (white ki) and Ultimate CHAD Ki (black ki) the fusion known as Gris (Gray) appears, resulting in a power unmatched.
Gohan Gris will appear when he decides to fight El Dios Dragon at the series finale and saves the multiverse from total destruction.
