Silver Age Powers Ive been reading the House of Secrets issues starting with Eclipsos debut and have hit issue  Thus far Eclipso does not display superstrength or partial invulnerability or any other such thing he is only able to shoot beams of light channeled through his black diamond and has a geniuslevel intellect that is equal that of his host Bruce Gordon he can build robots handily manipulate people fly airplanes etc In the Bruce Gordon portion of this article it lists that Eclipso has generic supervillain powers which Ive yet to see I will finish reading these issues and correct for any contrariness
