Dream seems more like one to have others fight for her, if it was head on Ultima would win though.

Dreams...I'm almost sure those swirly things allow her to call up undead body guards...

Kali... she has claws...

Kali, hyjin's bunny hat just ruins it.

Hyjin...those horns may just be for show, but those wings are lethal...

Kali. She seems to know how to fight more and she has a weapon.

Kali

Ultima...that circle she's standing on has evil magic summoning spell written all over it...

Kali_Namir

Hero. He has blades D=

Ultima

Ultima

Alpha

They both look pretty dangerous but I'd say Hero wins this round.

Dark, only because he (?) has a minion wolf.

It would be a close one, but I believe Ultima would win!
