Frieza was one of the original characters to make use of the ever popular “this isn’t even my final form” joke. Throughout the Namek saga, Frieza was able to transform into a more powerful version of himself. Each transformation had him grow larger and stronger.
Until the final form where he
loses his horns and other details. The sleek and simple design is the most powerful. It perfectly captures the kind of character Frieza is. He continues to grow in strength and constantly surpasses the Z-Fighters. All a result of those fancy transformations.
