Some modes have a chance of turning into a reskinned version with different colors and/or music. These "rare modes" do not have any unique abilities, other than the moves from their original forms.
In addition to being described on the pages of their respective modes, all rare modes are also listed below.
Currently, all rare modes have a 1 in 30 chance of appearing, per rare mode (with an exception of Sugoma, Memer's rare mode, with about a 1 in 1000 chance of appearing).
