Pegasus

With the Champions having recently disbanded, Marvel Two-In-One #44 found Hercules asking the Thing for assistance. Powerful monsters had overrun Olympus, and Hercules needed help rescuing his father, Zeus.

The story introduced Hercules riding a chariot drawn by winged white horse. Although the valiant stead resembled Aragorn, the unnamed animal would have been the Pegasus from Greco-Roman mythology.
