Eclipse is the Final Boss and main antagonist of Mario & Luigi: The Shadow Saga. Not long ago, Eclipse and his brother, Sagaz conquered their world and then went on to conquer the mushroom world. Though, when Eclipse and Sagaz arrived, they were betrayed by one of their own and were locked away in another dimension. Eclipse was set free by Sagaz and then attacked the Mario Bros.. Eclipse was yet again sealed away in another dimension, known as the Twilight Cage. After Eclipse was defeated, his shadow stayed on the mushroom world to destroy Yoshi, though he was defeated. Meanwhile, in the Twilight Cage, Eclipse is controlling the place and is waiting for the right time for an assault on two worlds.
Eclipse' appearance somewhat resembles Elder Princess Shroob's Second Form. He has a large mouth with large teeth and has 3 large spikes on the back of his head. He has a red collar-like growth on his crest and wears a cloak. Eclipse also has crustacean-like pincers on his back and has his hands floating apart from his body. Eclipse has crustacean-like legs, tentacles and a Scorpion Stinger Tail. In overall, Eclipse is a force to be reckoned with.
