Vibravore was created by an accident. Scientist A'Kane was working on a project on "controlled interaction of Vibranium isotopes", trying to use interaction between Wakandan and Savage Land vibranium as a new energy source. The process was successful in generating energy but caused a chained reaction. The huge explosion which followed fused every human caught in the epicenter to a single horrific being. Vibravore could release massive blasts of sound and vibrations. It proved resistant to heat and force-blasts.
The Fantastic Force eventually found a way to separate the entity back to its human components. The subsequent fate of said components is unknown.
