Gnometown Hero
They had several characters of the same era, including their Soviet superheroes, who used dark energy and dark matter initially, but who then later were said to use darkforce instead, either because they got letters from angry astrophysicists or just from a housekeeping standpoint and wanting to link a bunch of darkness characters together.Hmm. I don't know about "dark energy" or "dark matter" in Marvel (though I know it was a Big Deal in the Alternity RPG back in the 90s). What they do have is Darkforce, which is energy/force from another dimension and which is primarily used by Cloak (whose body is normally intangible and a portal to said dimension) and Darkstar (who can channel Darkforce into making physical constructs, sort of like a Green Lantern, as well as fly and a limited form of teleportation).
