First Form:
Small, but powerful. This is the form that Frieza chooses to remain in to conserve his power. Not one had observed him in his final form until the battles on Namek. Frieza is a formable opponent with a long tail that he uses to immobilize his enemies so that he may use them as a personal punching bag. He is short, pink and purple and wears purple Saiyan Armor. Two horns protrude from either side of his head and he prefers to move about in a small hover chair. Frieza fights Nail, Piccolo, Gohan and Vegeta in this form.

Second Form:
Frieza looks like King Kold in this form. He is a lot larger and has longer horns. While he is in this form he stabs Krillin through his armor. Luckily, Dende revives him and Krillin throws a destructo disk that cuts off his tail. Gohan attacks him in this form and Piccolo finally arrives to fight the evil alien. Unfortunately, Frieza has another, more powerful form.

Third Form:
Frieza's most monstrous form. He transforms into a hideous creature that has a huge head and more pronounced horns. He retains the Saiyan Armor and battles it out with Piccolo. None of the Z fighters are a match for him after he assumes his third form. He does not stay in this form long as Vegeta challenges him and he changes to his most powerful fighting form.

Final Form:
Frieza's final form is his most powerful transformation. He transforms to defeat Vegeta and ends up blasting him through the heart with a quick energy blast. No longer wearing the saiyan armor, Frieza's final form is more sleek and toned. He no longer has horns or the pink color of his other forms. Instead, he maintains his rounded head and takes on a totally light purple complexion. He is faster and is able to kick Goku around. It is not until Goku reaches his Super Saiyan form that he powerful enough to defeat the evil alien.

Metal Frieza:
After Namek is destroyed, Frieza, who we thought was destroyed by Goku, survives. He is floating in space (remember he can breath in space) when he is found by his Father, King Kold. Using advanced technology, Frieza is reconstructed. By using electrical components, Frieza becomes more powerful. Frieza, consumed by his thirst for revenge against Goku, travels to Earth to destroy it. He arrives before the Saiyan and attempts to send out men to find Goku's friends. Before they can get a few feet, a mysterious boy arrives and kills them. He easily deals with Frieza's men and confronts the evil villain. Frieza is surprised to find that the young boy is a Super Saiyan. The boy, who we learn later is Trunks, easily chops Frieza up into little pieces and disintegrate them in one blast. Trunks then easily defeats King Kold.
