Frieza The Great is a famous evil with the poisonous, sinister, cruel and fraudulent nature that contributes significantly to the attractiveness of the Dragon Ball comic series.
Frieza appeared for the first time in a small shape, red skin, with 2 horns on the head with a power index of up to 530,000 …
… and always sat in his mobile chair to order the henchman to do everything.
The first impression that Frieza appeared in Dragon Ball seemed enough to make anyone facing him was scared.
Frieza sat on a small ship, with just a simple movement of a finger, he murdered all Saiyan races and destroyed the planet Vegita. That is why Vegeta, Kaiosama and all those who know Frieza are afraid of him. However, among them no one suffered from Frieza fear as much as Krillin.

After the first transformation, Frieza's body became taller and no longer in the mobile seat. At this time, his speed and strength doubled compared to the original form.

In the second transformation, his strength increased 4 times compared to the original form.
Goku's most close friend witnessed Frieza transforming to achieve higher strength, whenever he was threatened in the battle that took place on Namek planet. The first transformation, Frieza had a huge body and horned on the head. The horns pierced through the Krillin body and made him stand on the brink of death.
This moment in Dragon Ball has made Krillin obsessed with every transformation of Frieza.
So, thinking of Frieza for the last time, he was unable to stop himself thinking and imagining.
Just before Frieza reached the final shape of the change, Dragon Ball Z showed what was happening in the mind of the Master Roshi's disciple, about what the final transformation of the universe Emperor would be like.
Krillin imagined a scary monster. He thinks the last shape of the conqueror of the world will be like what we imagine about evil aliens in science fiction films since the mid -1990s.

Frieza follows Krillin's imagination
Finally, what we see about Frieza's final shape in Krillin's imagination is not true. The emperor of the universe has achieved transformation into a simple physiological creature, the closest to humans.
Frieza in the last form in Dragon Ball Z has a small appearance, full -gray body and purple details. He has a round bald head and a large tail, can use it as a weapon if needed.
