Hot Nixod was a hybrid between Nixod 17's leftover DNA (which had some residue of NIxod 6) and what was left of Nixod 24's body. Somehow the DNA mutated and made it female. No one understood why. Thankfully, since the "18 experiment" Nixods are top secret, Noxid didn't find out about her. Hot Nixod has a mad admiration for Rat.
