2 of the Eternals characters are black and they don't have electric powers.
they technically robots in black face, they don't have any african roots.
Not nitpicking either, i prefer serious representation with characters that are rooted in black culture. Not just a robot that looks like a black guy or a black skinned alien.
Their ethnicity should be a part of their background (like magneto/jewish origin affects his whole character) or else it doesn't count. Thats why people like Black Panther, Storm, and Luke Cage
