Ay is a minor antagonist in DreamWorks' 28th full-length animated feature film Mr. Peabody and Sherman. He is King Tut's vizier and the leader of the Egyptians.
He was voiced by Steve Valentine.
After Sherman sent Penny Peterson to Ancient Egypt via the WABAC, he returned with Mr. Peabody to get her back. As Mr. Peabody tries to convince Penny to come back with them to the present day and not marry King Tut, Ay comes into the picture and introduces himself. Ay then informs Penny that he intends to sacrifice Penny as a sacrificial tradition during her marriage with King Tut at dawn. Penny regrets being part of the marriage due to the painful price and tries to leave, but the guards block her path and they take her away. Sherman tries to intervene, but he and Peabody are thrown into a tomb and imprisoned.
Peabody and Sherman manage to escape the tomb and head to the palace to stop the marriage. Before Ay could sacrifice Penny, Peabody stops the rite under the disguise of a nearby Anubis statue and instructs him to take Penny back to the gates. However, the jaw of the statue falls off, revealing Peabody and Sherman. Penny flees with the duo and King Tut complains about his bride running away from him. Ay orders his guards to stop the trio, but they manage to escape onto the WABAC. The Grand Vizier then angrily throws his blade to the ground and a mischievous passerby picks it up and runs away.
Ay is later seen in the modern world, along with various other historical figures after Ms. Grunion accidentally caused a cosmic rip in the space-time continuum as she merged Peabody and Sherman's cosmic doubles in the same timeline. Along with all the other historical figures and Ms. Grunion, Ay is sent back to his timeline with King Tut after Peabody and Sherman manage to close the rip in the space-time continuum by travelling to the future. After getting sent back to his era, he was seen dancing with the other Egyptians.
- In real life, Ay was the brother of Amenhotep III who was the grandfather of Tut, making Ay the great uncle of Tut.
