Mega Man (Archie Comics)
In the comic, the Wily Tower is a research institute called Chronos Institute that is researching time travel, as evidenced by the appearance of a disabled Time Man lying in the corner on the first page. Dr. Wily invaded the institute with the Genesis Unit and the Mega Man Killers to take over a time-travel device. Using the device, Wily remodelled the institute into a fortress. Shortly after, Mega Man appears to stop Dr. Wily, and he is hit by the device's energy, which sends him to different time periods.

Trivia

 * The paths shown in the game's map doesn't correspond to the stage's layout. For example, the map shows that the last stage's path leads to the top of the tower, but the stage is mostly a descending area. It also doesn't reveal alternate paths.
 * Mega Man: The Wily Wars' Wily Tower is inaccessible on the AtGames Sega Genesis Ultimate Portable Game Player due to it not being able to save after beating Mega Man, Mega Man 2, and Mega Man 3. It does work on the Sega Genesis/Mega Drive Mini, however.
