Same glow effect that happens to khali considering her humanoid parts are also Raven tech

kin claw is revealed as claw

the last episode where he is revealed and stands in the rain as the rain whipes off the makeup

finally removes mask to reveal as claw thus we know claw didnt die in the previously and that he was also an Raven all along, we find out his watch was fake (strong purpose behind this that back a good reason why claw succeeded by having fake watch)

we also see his makeup wear off

big twist reveal that claw is actually kin claw all along

after fate is vaporised by claw the crystal falls to the ground and vaporises as well

this is the first official fight between claw and fateus and claw kicks his ass, he literally destroys the crystal, this is why the only thing kaly can do is take herself and claw both together off the edge

and thus why fateus follows after them

When claw attempts to control parts of khalis humanoid design her veins and skin glows orange
