History
Valinor was the second winged steed of Dane Whitman (the heroic Black Knight) who obtained him while inhabiting the body of his ancestor, Eobar Garrington. Valinor's origin is unknown, though when first seen, the Knight was on a mission for Merlyn, so presumably the horse was provided by him.
He aided Black Knight numerous times during his battles along S.H.I.E.L.D.'s alliance against supervillains who tried to acquire the valued Isotope-8.[1]
