These are the villains I made for the DBZ fanfic years ago.
The one on the right is Zerogue, a fossil saijin more or less that was once trapped under thick ice (which is why his hair and tail is white) so there for survived and broke free somehow with ice abilites at the cost of his own voice.

The one on the left is one of the elite clone saijins that was said to be the toughest to beat, they could take down an ssj 2 without transcending. This one used to be called Nasu, but I changed his name to make him more of an individual character. He's no grunt unlike his last sketch, his blue hair is due to the mix of dna in his body that makes him a formidable villain. I took away the tail from Okura because he only have the abstract of saijin blood with a mix of other dna.
