The Big Guy

The Big Guy was a Twi'lek, believed to be the father of all Twi'leks. He was massive, and spoke a mysterious language that everyone feared. His terrifying appearance and demeanor led to him attempting suicide, which resulted in his homosexual partner's death. This led him into a deathstick-induced rage, killing millions of Twi'leks with his bare fists.

Purpose
This character is literally pointless. George Lucas meant for him to be a main character, yet this was scrapped. It was believed that The Big Guy was originally supposed to take Jar Jar Binks' place.
