Boba Fett:  Most known and feared Bounty Hunter throughout the galaxy. Was hired by Darth Vadar to find Millenium Falcon, captured Han Solo at Cloud City, knocked into the Sarlacc Pit by Han Solo, "died" in Sarlacc Pit.
 

DARTH MAUL:  Known for his lightsaber, the apprentice of Darth Sidious and one of last survivors of the Sith, Darth Maul is one of the toughest beings in the universe. Some have argued that he is more powerful than Darth Vadar himself. In Episode I, we only see a little glimpse of him fighting our young heroes. He unfortunately dies in the first episode, where now we know little about him. He was cut in two by young Obi-Wan Kenobi.
 

Darth Vadar:  Born- Anakin Skywalker. Wife- Queen Amidala. Children- Luke Skywalker and Leia Organa-Solo. Mentor- Obi-Wan Kenobi. Master- Darth Sidious, a.k.a.- Senator Palpatine, a.k.a.- Emporer. Was found to have the highest ability in the Force and perceived as "The One," was taught in the ways of the Force by Obi-Wan, got hungry for power and temptation, fell to the Dark Side under the guidance of Senator Palpatine, hunted and killed all known Jedis according to their knowledge, was turned to the good ways of the Force by his son Luke Skywalker, killed the Emporer, and soon perished after that.
 

Emporer Palpatine:  Formerly known as Senator Palpatine. He announced himself as Emporer to take control of the Senate and gain personal power, his second hand man is Darth Vadar, with them as a team, they destroyed almost all of the Jedis in the universe, the Emporer hates all aliens (pro-human) that is why he has destroyed so many races and civilizations in the known galaxy, his final "battle" was on the second Death Star where he tempted Luke Skywalker to the Dark Side but fails, his apprentice- Darth Vadar throws him over the railing into the core of the second Death Star supposedly "killing" him, but actually during the fall he was transferring his consciousness into another one of his clones (more on this later)...
 

GRAND MOFF TARKIN:  Born and raised as an Imperial officer, he lives by the book and goes beyond when it comes to getting his way. He gave the order for the destruction of Alderaan on the first Death Star. In his cockiness, he refused to abandon ship and perished with his first dream- The Death Star.
 

JABBA THE HUTT:  Always thinking of himself as a superior being in the galaxy, Jabba the Hutt is a gang lord that deals with illegal trading and transactions. He wanted pay backs for Han Solo dumping his cargo, so he sent in a bounty for Han Solo that no one could refuse. Jabba suffered death upon his sail barge in Tatooine, allowing Han Solo and his friends to escape unharmed.
 

STORMTROOPER:  These are only minions by the Empire. Brainwashed to have no emotions, they are the perfect army because they don't care if they live or die. All Stormtroopers are human because the Emperor hates everything that is not human. They perform their duty with no remorse and since there are so many of them, they overwhelm any enemy.
