Ulysses S. Gr-ant was summoned and named by Ant-Man to be used as his mount for an infiltration mission inside Ghost's hideout. Once Ant-Man shrunk himself, Ulysses S. Gr-ant flew to join the Wasp, who had reduced her size as well. The ant then went through a crack in the door to enter the building, and then led Ant-Man to a table where the Mobile Laboratory which had been stolen from them was laying. Ant-Man then returned to his regular size, no longer needing Ulysses S. Gr-ant's services.
- Ulysses S. Gr-ant is named after 18th President of the United States Ulysses S. Grant.
