Trioculus

The Mandalorian spent a very long time setting up connections to mysterious cloning experiments and dark magics over its three seasons, only to seemingly snuff out the root of all those connections almost as soon as they were revealed: Moff Gideon’s would-be army of cloned Force sensitive versions of himself, the next generation of Dark Troopers. But Star Wars loves a mysterious cloning experiments and dark magics moment! Why not more?
Another Warlord introduced in The Glove of Darth Vader, Trioculus was the secret product of genetic experimentation and manipulation by scientists working for Palpatine while he was still Supreme Chancellor. An attempt to create spontaneously generated life, Trioculus was the sole “success” of the experiments, a mutate with a third eye in the center of his forehead. Raised by the Prophets of the Dark Side as the heralded son of Palpatine, Trioculus was presented as an alternate successor to the Emperor against Ysanne Isard, seeking the glove of Vader to prove his prowess.
Trioculus would be a wild pull, but a very cool way to tie back around into all those cloning experiments and supernatural magicks that saw people connecting what The Mandalorian put down to the eventual return of Palpatine himself.
