There are going to be multiple transformations in this story that I will be making up as the story progresses. As for why I will be making up transformations, it is because it would be boring if Gohan went SS3, then God, then God Blue, then Ultra Instinct, and then Beast. That's just copying Goku. Instead, I decided to make up forms that lead up to Beast and also use some of Goku's forms as well, but not all of them. No, I will not be taking suggestions, I want to do it my way. Sorry.
This is the index in case readers lose track of them or if you want to spoil yourself I guess.
Gohan at the start has Super Saiyan and Super Saiyan 2.
IMPORTANT SIDE NOTE: A technique being listed as 'Similar Techniques' does not mean they are similar in strength or scaling. They are similar in the way that they are performed.
Transformation 1:
Tempered Super Saiyan 2:
Appearance: Blonde, spikey hair that is extremely similar to a standard Super Saiyan 2. The eyes are also the same as a standard Super Saiyan. The electricity that comes from the body is purple rather than blue. This form is the introduction to what will be known as Beast Ki, seen by the blue aura and purple electricity.
Power: Multiplies the base strength of a Super Saiyan 2.
