EverymanHYBRID
The Rake, known in this continuity as The Feral Other, appears as a recurring antagonist in the EverymanHYBRID webseries, portrayed as a feral, dog-like creature in the service of HABIT and an ally to the Slender Man.

WhisperedFaith
A more malevolent adaptation of the Rake, known as The Speaker, appears in WhisperedFaith as one of the two main antagonists. It is extremely intelligent, and uses its speech to torture and corrupt victims by making them addicted to the sound of its voice, resulting in them going insane and turning into its homicidal pawns.
