In the video game Dragon Ball Fusions there are several hybrid forms that are the result of fusion causing two or more distinct forms to be merged into one new one.
Super Saiyan and Legendary Super Saiyan hybrid
A form utilized by Karoly. In this state the user primarily maintains the appearance of a Super Saiyan, with mostly gold hair, though the hairstyle more closely resembles that of a Legendary Super Saiyan, and the frontal hair is colored green like a Legendary Super Saiyan.
Super Saiyan and Super Saiyan 4 hybrid
A form utilized by Tekka's Ultra Fusion when a pure Saiyan male or female characters (such as Kid Goku in the story) is the one to instigate the fusion (or Tekka is a male Saiyan). In this state the user appears to be a golden Super Saiyan 4, though the hair on their arms does not go all the way down and is restricted to their shoulders.
Ultra Pinich also appears as a golden Super Saiyan 4 but his fur is limited to the upper portion his back and under part of his chest.
Super Saiyan Rosé and Legendary Super Saiyan hybrid
A form utilized by Karoly Black. Appearance-wise, it is nearly identical to the Super Saiyan and Legendary Super Saiyan hybrid used by Karoly, however, the gold parts of Karoly Black's hair are pink instead.
