The Rain Core is an elemental using Storm Magic. It is the last boss of the Under Den instance in the Thieves Den of Mirage.
Rancors are towering hulks of muscle and reptilian flesh that walk on two stubby legs and use their disproportionately long arms to capture prey. A salivating, tooth-filled maw dominates their flat faces, and their armored skin is so tough that they can shrug off blaster bolts as little more than annoyances.
Jabba the Hutt kept a rancor in a shadowy chamber beneath his Tatooine throne room. After Luke Skywalker killed the beast, an outraged Jabba ordered the public execution of the Jedi and his friends.
Boba Fett also kept a Rancor as pet/battle mount when he became the crime lord of Mos Eisley on Tatooine.

Although I am well versed in Pop Culture references but I do not claim to have caught them all. Let me know your favorites in the comments and if I’ve missed one you caught, let me know so I can add it to the list.
