Ize

Ize is Frieza's son and the main antagonist of Dragon Ball AF (Youngjijji)'s first saga, the Ize Saga. Ize is a Winter (Frieza's race) who was born 50 years before the start of the series, and has just awakened from hibernation for the first time, he seeks to relieve stress and seek out the ones who killed his father.

1st Form
His initial appearance is mostly the same as Frieza's final form, but eye and skin color are different, plus his chest and face have red markings. Because he built up a lot of stress during his long thawing period. Ize travelled around the universe looking for powerful foes.

2nd Form
His body has enlarged and his power and speed have vastly increased. Even Super Saiyan 4 Vegeta wasn't able to scratch him.

3rd Form
With a perfect body concealing power over 10 times greater than Frieza's, He's without a doubt become a foe stronger than any seen before.

Power
Ize's regular form is described as having power 10x greater than Frieza's maximum. Ize is capable of outmatching Super Saiyan 3 Vegeta, and trading blows with Super Saiyan 4 Vegeta in this state, but is outclassed. His second form is superior to Super Saiyan 4 Vegeta - so much so that Vegeta cannot scratch Ize, but the combined might of Super Saiyan 4 Gohan, Super Saiyan 4 Vegeta, Super Saiyan 3 Gotenks, and Majuun make him decide to transform. In his Perfect Form his power is described as incredible by Super Saiyan 3 Gotenks, and Super Saiyan 4 Gohan states that he is on a whole different level after Ize reflects Gohan's Ultimate Kamehameha. Ize's Perfect Form is described as a "Without a doubt, a foe stronger than any seen before", making his power superior to that of even Omega Shenron, his power can be further enhanced when he goes to full power, however, he is unable to defeat the enraged Super Saiyan 5 Gohan.

Going by official power levels, Ize's regular form should have a power level of at least 1,200,000,000 (10x Frieza's power level during the Battle of Namek) or 14,399,414,100 (10x Frieza's GT power level according to Scouter Battle Taikan Kamehameha). His Perfect Form should have a power level over 1,900,000,000 (Omega Shenron's power level in Scouter Battle Taikan Kamehameha).
