Gravity Flips were first made available in the devkit for Make a Good Mega Man Level 2, where they appeared in nine entries, as well as the Wily stages Inner Sanctum and Reality Core, the Tier X stages So Good and Swiss Hotel, the Pit of Pits sub-levels "Flippin' Tops", "Once More, With Ceiling", and "Up And Down", and Null and Void. They also appeared in Make a Good Mega Man Level Remastered's remade Wily stage Flashback Database, and in Tier 3. Gravity Flips made a further appearance in Make a Good Mega Man Level: Episode Zero's version of Null and Void.
If Mega Man touches a Gravity Flip pointing in the opposite direction of his current gravity, his gravity will be flipped to match the Gravity Flip (i.e. touching an upwards Gravity Flip turns Mega Man upside-down, and touching a downwards Gravity Flip turns him right side up). If he touches a Gravity Flip pointing in the same direction as his current gravity, nothing will happen.
In Orbital Station, Gravity Flips will cause Mega Man's movement to lock until he touches ground without Gravity Flips placed on it.
