I'm trying to build a fusion with skittles

I'm debating between 3 of my TF OCS to fuse with this rainbow fag-

Now here they are! I want y'all to vote!

Sorin
F
Short galactic randomizer(SOON TO HE RELEASED SPECIES)
Sor has a thin metal sheet surrounding her waist seeming as a skirt. Her metal is a fair shade of a Navy blue, the thin sheets of metal on her waist and back are a galaxy color.

Etio
M
Big ol childish mech. He's a pitch black mech with only white eyes- he has sharp white servos/claws on his hands and feet.

Tina
F
She's a small short femme with a white frame(She's basically the twin of this fag-)
