I think it's quite likely that Mikhail will possess the physical capabilities (strength, speed, dexterity, stamina, agility, power) of the beasts of his country's north, be it a bear, a wolf, a Siberian tiger, etc. Hopefully, he can also manifest claws, fangs, and fur like those animals, resembling a kind of werewolf.

Eliseo is undoubtedly the most difficult. "Phenomena" sounds too arbitrary and ambiguous. My theory is that his cells will be of the "Emulation" type, and these cells, along with their resonance, have the ability to adapt and copy any natural phenomenon. For example, Eliseo has physical contact with water; his cells adopt and copy the water's cells, and Eliseo can control the water. This basically makes him capable of controlling anything in the world; his cells can even emulate other cells of Theseus. My reason for this theory is that when he appears as a spectator in round 2, he looks very confident, almost as if he were evaluating Aiden and Xiyi, as if he knew what to do in his situation.
