 Gateway also possesses psionic abilities that allow him to communicate with telepaths.Gateway once spoke to the telepathic Generation X member Chamber psionically, as well as regularly communicating psionically with the St. Croix twins, then disguised as their older sister M.

It has also been implied that he possesses total recall or eidetic memory, as it was revealed in the alternate timeline of the Age of Apocalypse that his time-space manipulating powers allow him to be virtually omniscient, as he is described as "the repository of the knowledge of humanity, the living index of every hard earned scrap of information gleaned in our ascent from mindless savagery".In the Age of Apocalypse, Gateway spends most of his time on Wundagore Mountain, trying to physically absorb any and all knowledge in audio-visual format from hundreds of televisions and computers using his powers to slow time and warp space before the forces of Apocalypse destroy everything.
