I forgot to make a post but I feek like Kuriza would get a strong transformation like Frieza but in the worst way possible. I feel like Kuriza often feels guilt towards his family sins. Kuriza doesn't want to be a cruel emperor and feels like he has to make up to what his father did in the past. So he gets powerful by not hurting others but himself
There's probably a traumatic scene that happened and Kuriza loses it, there's no screaming or sobbing, just the deathly silence as Kuriza is being swallowed by despair. I feel like his hazelnut color would darkened like maybe to Maroon? I think this would the pallete to his depressed powerful form
He doesn't get a shiny form like Golden Frieza because Kuriza feels he doesn't deserve it. Despite feeling guilty for the pain his family caused, ironically, Kuriza ends up hurting others. You see, Kuriza's powers are out of control, so technically it's very dangerous. I imagine Kuriza is accidentally creating a massive black hole, even powerful than Frieza’s black ball. In fact, Kuriza's sudden new powers tried to kill him
Kuriza only calms down when Bulla comes to him, telling him it's not his fault and what matters is to always try to better. Only then Kuriza calms down and loses his new transformation
Poor Frieza anxiously walking back and forth that he got what he wanted, for Kuriza to finally be as powerful as he, only for Kuriza be in danger of his own powers as Frieza realizes he almost lost his son and realizing Kuriza's power originates from self-hatred
Frieza is just laying in bed, wondering where did he go wrong but then Cell comforts Frieza, this is one of the few times where Cell is deeply serious. Cell's reassures Frieza everything will be ok, they will find a solution to Kuriza's powers
