The parallel key: the other mode on the same tonic.
The tonic keeps the spelling it was given — the parallel minor of C major is C minor, never B# minor — which is why this is the one relation here that does not travel the circle of fifths.
The spelled tonic of the key, as a note name, note data, or a Note; its letter and alteration are kept.
Note
The key/scale, as a key name, a key/scale, or a Key; its mask decides which mode the parallel is in.
Key
The parallel key on the same tonic.
If the tonic or the mask is malformed.
