Frieza (What If 13)

Frieza, in this What If, comes from the GT Era, and after spending training in Hell, he gains access to the Golden Form, among other transformations.

Appearance
In his Final and Golden Forms, Frieza looks identical to how he looks in canon. However in his Fifth Form, Frieza grows taller and buffer, grows spikes on his outer forearms and lower legs, and gains the iconic "mask" over his mouth and nose.

Personality
Frieza is vicious, and seeks to destroy any and allin his way; identical to his canon counterpart. As he battles Goku in What If #13, Frieza is very confident, but not cocky, as he is in full control of the situation.

What If #13
In What If #13, Frieza takes advantage of his countless years in Hell to train with Perfect Cell; resulting in the two of them gaining their Golden Forms, and Frieza learning the Fifth Form like his brother Cooler. After gaining the opportunity from Dr. Gero's and Dr. Myuu's 17s creating a gateway between Earth and Hell, Cell and himself challenge Goku to face them in Hell. Goku accepts, but is quickly trapped in the process, while Dr. Gero, Dr. Myuu, and Hell Fighter 17 escape to Earth to continue with the plan to create Super 17. Frieza confronts him first, and they battle, before Frieza reveals Golden Frieza. Golden Frieza is far stronger than any of Goku's other forms; forcing him to transform into Super Saiyan 4. The two fight more, but it's clear to both parties that even with Super Saiyan 4, Goku's fighting a losing battle. Frieza crushes Goku despite his various desperate techniques; (using the Kaio-ken, exploiting Zenkai Boosts, etc.) and reveals that there's no way for Goku to win. Frieza confirms that he has perfected the Golden Form, briefly shows off his Fifth form, and lastly reveals the fact that Perfect Cell has also gained similar power. After Goku is pierced by a Special Beam Cannon from Cell, Frieza and Cell reveal that this was all apart of their plan, Frieza would wear Goku down, and finally, Cell would absorb Goku; forcing him into an eternal limbo, not unlike the fate that Frieza and Cell had shared in Hell. With that, Cell absorbs Goku, gaining tremendous power, and with the remaining Z-Fighters killed by Super Android 17, Cell marks the victory theirs, once and for all.

Power
In the [What-If Universe Official Power Scaling], Frieza is ranked the following:


 * Rank 49 (Final Form + Post Training)
 * Rank 21 (Golden Form + Post-Training)
 * Rank 15 (Golden From + Fifth Form + Post-Training)

This Frieza is confirmed be far stronger than the Frieza in Dragon Ball Super, and possibly could've gained a Sixth Transformation after the Fifth. Even after Super 17 absorbed the power from Vegeta, Gohan, Goten, Trunks, and Majuub, Goku still claimed Frieza was stronger than him.

Also, Golden Frieza is shown by the Official Power-Scaling video to be above SSJ Blue Kaioken-x10 and a SSJ Rose Kaioken-x10 Goku Black in power, and is at least as strong as base Jiren according to the same video (although considering that base Jiren is put below Beerus in the power-scaling video while the actual DBS anime establishes him as likely being stronger than Beerus in base form alone, this is very debatable).

Frieza's Golden Form + Fifth Form is even stronger than this, being ranked above a Golden Cell with God Ki from What-if 6 (who was far stronger than he was without God Ki, and even without God Ki he was easily stronger than Kaioken-x10 SSJB Goku and SSJB Vegeta), SSJ God Gogeta, and Golden Cell from What-if 12 (who is stronger than 'normal' Golden Frieza). He is only 1 rank below SSJ God Kaioken-x10 Gogeta, which implies that he is either close to or equal to the power of SSJ God Kaioken-x10 Gogeta, who matched Base Jiren and still held his own against a Full-Power Jiren.

Going by this mixture of established and hypothetical scaling, it's reasonable to say that Golden + Fifth Form Frieza is close to the level of a God of Destruction, especially since SSJ God Kaioken-x10 Gogeta (whom he is only one spot below in the power-scaling video) is 1/5 as strong as SSJ Blue Gogeta, who (if we assume is as strong as he was in the canon DBS: Broly movie) stomped a Full-Power SSJ Broly, who is "probably" stronger than Beerus.

Trivia

 * Frieza's power in What If 13 is slightly unclear, as Frieza was also unable to take any permanent damage, due to the conditions of Hell; this was even seen after Goku ripped off his tail, only for it to grow back within seconds.
 * Appears to have knowledge of the various forms, fusions, and transformation, gained in the time of his death, and further beyond. It is not explained how.
 * Frieza could've been viewing the situation from Hell, very much like Cell (What If 6).
 * This also could have been artistic choice, and Frieza could've merely been commenting on the situation.
