We meet the character that I’m dubbing “The Mad Scientist” while under the ruins of Sundari, the former domed capital city of Mandalore. When we meet him, he is surrounded by dozens of empty Mandalorian helmets, presumably of his previous victims. He looks essentially like a Rahkshi from “Bionicle,” an empty cybernetical husk controlled by some small creature with weird spines on its back. This alone is enough of a terrifying look to deliver some chills, but it also makes you want to lean forward and learn more.

Indeed, while The Mad Scientist is scary, with his single, cyclops-like eye peeping out, he is also a scientist. After easily trapping Din Djarin, using an electric baton to incapacitate our Mandalorian, he places him in a small cage. Here, The Mad Scientist starts his sadistic experiments, literally draining Din of his blood in order to, well, we don’t know, but that’s what makes the character intriguing.

In addition to a fantastic body horror vibe, what makes this scene interesting is how vague this character is. If he is actually a scientist, what the hell is he experimenting on? It’s not like there are a lot of Mandalorians left, so are they just torturing Alamites, or spending months and years on end just waiting, begging for a new subject to stroll down the empty ruins of Sundari for them to capture? My money is on the latter. Just picture it: this weird creature in a massive spider tank crawling around the city in search waiting for a new subject to study, going home at the end of every day feeling a little more hopeless. Din Djarin stumbling onto his cave may have been his happiest moment in months, and I’m so glad that I can share in his twisted joy.
