In the first movie of Digimon Tamers, Mephismon, a Digimon from another universe who was originally an Apocalymon (And this Apocalymon was supposed to be the same from the first season, but the creators of the movie decided to change that for some reasons.), fought against an Omegamon and escaped to the Tamers Universe.
Mephismon also survived a shot from the Garuru Cannon.
In the Tamers universe, Mephismon creates an artificial world based on what he wanted to do to the Real World.
This world disappeared when Gulfmon was destroyed by MegaloGrowmon, Rapidmon and Taomon. When Mephismon envolved into Gulfmon, he destroyed part of the city.
