There is at least two logical answers. One of which I don’t need to name for obvious reasons and the other because she’s the Ki version of Juri so yeah.
Aqua - Shark-Human hybrid: Genetic experiment done by UltraTech to make an aquatic warrior.
Warrior - Crusader: Wielding a flail and a shield that has access to the abilities of Holy powers. Possibly a statue of an English warrior from the Middle Ages brought to life.
Spellcaster (or Pyro) - Fire Sorceress: Grew up on a small island in Hawaii. She was kidnapped by some fanatics who tried to sacrifice her to their god, but instead became an instrument of its power. After she killed the fanatics by accident, she fled her home to learn how to control it for the betterment of humanity.
Reptile (Beast-Warrior) - Gorgon: Basically just search for the Slither Topic that (I think) @xSkeletalx made.
I’ll think of some more later. (Nice Yu-Gi-Oh reference there though)
Fish - Merfolk is best since Rikuo from Darkstalkers. There can be a survivor of Atlantis who desires to restore the ancient city.
Dragon - After Gargos - as a gargoyle, new enemies can involve a dragon. A humanoid dragon.
Insect - Now that Riptor is a cybernetic raptor, a hybrid of insect & human blends in. If done Frankenstein, it’ll be designed with pieces of various insects with various abilities from each one. A mantis’ blade, a bee’s/wasp’s/hornet’s stinger, centipedes that can stretch & beetle shells, etc.
