Injected with a bioadaptive genetic serum and grafted animal parts by the Secret Empire, John Horton became the monstrous Griffin. Arrested following his defeat at the hands of Beast and Angel, Horton soon escaped after his body further mutated new features. However, as Horton’s features became more animalistic, his human personality was removed, leaving only the Griffin.
The Griffin’s genetic structure actively evolves, responding to stress by adapting the creature to better deal with its opponents. With the dissolution of Horton’s mind, the Griffin experiences less stress, and thus its form has been relatively stable in recent years. While Horton’s mind was still active, he displayed the ability to control certain avians; however, this ability has apparently not survived later changes. The Griffin has proven able to track people/places across continents
