>>16331685It's simple really -- though it assumes one can draw. You take 3 of your favorite (doesn't have to be top 3, any 3 will do) Pokégirls and use them as a base.
Say if my favorites were Maylene, Katherine (Furisode) and Ace Trainer (Unova). They'd be placed in the top center, bottom left and right corners as a reminder of what to work with.
Say Maylene's top center and Gen V Ace Trainer is in the bottom left corner. Top left corner would be a fusion design of Maylene and Gen V Ace Trainer. Top Right would be Maylene and Katherine's fusion. Bottom center? Katherine and Gen V Ace Trainer's fusion.
The exact center would be the fusion of all 3 at once.
