Freak
The Armadillo Man, or Freak, is not a cute animal. On Earth, armadillos are considered adorable animals, but in the MCU, they’re the complete opposite. Freak is a drug addict who was chased down by Spider-Man. After Freak injects himself with animal stem cell fluids from Dr. Curt Connors’s lab, he develops a flesh cocoon chrysalis. He did this because he thought it was an illegal substance, though he got a wake-up call when he learned it wasn’t. He was then shot down by the police, where he formed another chrysalis. Not only did the substance make him skinless, he was horrifying to look at. He can bring himself back to life, making him capable of surviving any danger. Ultimately, in the MCU, he fits right in, but that doesn’t mean he’s nice to look at. For a Marvel villain, he’s comparable to all the other terrifying ones (Ultimate Marvel).
