Hyp's Father

Hyp's Father is the quaternary antagonist, turned into a supportive anti-hero, in the third Land Before Time installment, The Time of the Great Giving. A grumpy Hypsilophodon, trying to control his teenage son through brute force, Hyp's father eventually learned the error of his ways and made an effort to reconcile with his son with softer feelings. He is briefly featured in the finale of Heroes vs. Villains War, along with the grown up dinosaurs, although it is unknown if he is actually supposed to be presented or if he is only there in the footage used.

Heroes Vs Villains War
Hyp's father only appears in finale of the war, as one of the dinosaurs threatened by Hades' pet, the Hydra. Other than that, he doesn't make another appearance in the tournament.
