By now, you've probably finished watching all 13 episodes of Fuller House and can't wait for Season 2 to debut. But during your binge-fest, did you happen to notice a familiar face from the old Disney days? A villain who scared the bejeezus out of you in the late '90s?

You remember the ever-charming Kalabar, right? The Halloweentown villain?

He was played by veteran actor Robin Thomas, who looks a lot better without all of Kalabar's makeup.

Thomas guest-starred on two episodes of Fuller House, playing Dr. Fred Harmon, D.J. Tanner-Fuller's (Candace Cameron Bure) boss and father to Dr. Matt Harmon (John Brotherton).

He's the reason Matt is harpooning in on D.J. and Steve's (Scott Weinger) reconnection, and that's simply not cool. Well, unless you're shipping D.J. and Matt, then you can thank him.

The first episode Thomas guest-starred on was Episode 4, "The Not-So-Great Escape." He tells D.J. he's leaving Matt at the clinic to help her out while he goes on vacation. YEAH, THANKS A LOT, BRO. Now Steve has competition.

His second episode occurred toward the end of the season, in the Bollywood episode that's unfortunately an example of cultural appropriation. The "Indian-themed" party was to celebrate his retirement.

Of course, there's an important, nay, vital aspect to Thomas's appearance we need to discuss. He sports a ponytail.

Let's zoom in for a closer look, shall we?

Amazing. Although, it's hard to picture Kalabar having a ponytail, since I'm so used to seeing him with bushy, curly hair. I realize Halloweentown came out 18 years ago, and people tend to change hairstyles, but this ponytail business is just throwing me for a loop. You do you, Kalabar Robin! You do you.

Since Thomas's character is moving to India to retire, it seems unlikely he'll return for Season 2 of the show. But you know who should join the second season? Someone who knows a thing or two about joining the squad a movie later. I believe he goes by "Kal"? Just a thought, Netflix. (Wink, wink.)
