Hmm let me see war god gains the paddle and paddle related attacks and think that's it
Sun god gains Sun choke and the Supersaiyan power up which allows him to cash out and parry
Blood good gains totems although three totems they are still related totems and parry
What I'm trying to say is that what makes them unique better fucking crazy because their base movements and movesets will be the same I hope that kinda explains what I'm saying
What?
War God exclusive moves:
-Saw Blade: Kotal swings downward for a damaging mid hit that cleaves the opponent.
-Overhead Sword Strike: Kotal does a far reaching overhead chop with his weapon that can also hit aerial opponents. Hit's twice when EX'd.
-Sword Sweep: Kotal does a far reaching low sweep with his weapon.
-Sword Toss: Kotal chucks his macuahuitl for a slow but damaging projectile. Multi-hitting with meter.
-Sword Quake: Kotal does a quick slash into an unblockable ground slam. Holding up will cause the second hit to be cancelled.
Sun God exclusive moves:
Moves:
-Sun God Choke: an unblockable command grab that can stack on top of itself three times.
-Soul Scorch: Kotal uses his command grab stacks to give himself meter. using meter during this move will instead give Kotal health.
-Soul Spark: Kotal beams with energy as he gains a stack of Sun for his other specials.
Blood God exclusive moves:
Moves:
-Crystal Totem: This total gives Kotal a 20-25% damage increase while it is active.
-Obsidian Totem: This decreases Kotal's damage takes by 20% and also increased his meter when he blocks attacks or is hit.
-Blood Totem: When active landing attacks will fill the totem with the blood of your enemy! After a few seconds the totem's stored energy is sent to Kotal. It shatters if Kotal is hit.
What i'm saying here is, assuming by "powers" you meant "special moves", Kotal, and many others, have more than two unique moves per variation.
Sektor has missiles, tele-punch, and flamethrower. That's three, MKX has characters with three special moves in a variation.
Cyrax has bombs, net, saw blade, teleport, and that spin kick that I can't remember the name of, that's five, MKX has characters with five special moves in a variation.
Smoke has a sliding teleport, invisibility, smoke bomb, tele-punch, and an air grab, again five.
My point is they're almost assuredly getting all of their special moves, it's nothing more demanding that what they've already done in the game already.
