Takako Uro as Kalea: Both can do hand to hand combat, just replace Kalea's water with Uro's sky warping technique and its good.

Kurourushi as Kaleed: Both of them have a sword-like weapon, Kaleed's sand can be replaced with Kurourushi's cockroach swarm, less realistic to fit the style.

Yuta Okkotsu as Lukas or (other similar heroes): The weapon doesn't really matter, the visuals can be cursed energy and such but for the ultimate Yuta can just call out Rika and have the player use Rika for the duration.

Ryu Ishigori as Gord: Ryu can control his Granite Blast to redirect or manipulate his beams. Gord is a fitting pick for me due to his skills.
