In addition, they've updated the profiles of several characters that will appear in the film including 'Anakin', Obi-Wan', 'Palpatine', 'Bail Organa' and 'Padme Amidala'.

The battle burns brightest in the scattered fronts of the Outer Rim Sieges. As desperation grows and heroes rise on both sides of the war, the Separatists, led by Count Dooku and General Grievous, make an ambitious strike at the heart of the galaxy. Thus the stage is set, and events are put into motion that will culminate in the fall of the Republic, the end of the Jedi order, and the rise of Darth Vader...

Here's a look at 'General Grievous' in the film...

Movie Picture

According to his SW.com profile, it seems this rival will be using a lightsaber against the protagonists in the film...

Gender: Male

Height: 1.904 meters (default configuration)

Weapon: Blaster pistols, lightsabers

Affiliation: Confederacy of Independent Systems

When the greedy corporate titans and the disenfranchised systems of the galaxy pooled their resources together to leave the aging Galactic Republic behind, they became the Confederacy of Independent Systems. Their military assets formed a droid army of seemingly limitless size -- a weapon that needed a military mastermind to wield effectively.

From within the ranks of the Confederacy came General Grievous, a brilliant strategist unhindered by compassion or scruples. His lightning strikes and effective campaigns caused his reputation to grow in the eyes of a frightened Republic. To many, he eclipsed the threat posed by Count Dooku, the charismatic leader of the Confederacy's political battlefields -- Grievous was the face of the enemy.

A twisted melding of flesh and metal, General Grievous' body is a deadly weapon forged by the cutting edge developers of the Confederacy. Within the hardened carapace beats the heart of a remorseless killer. Grievous hunted Jedi for sport and proudly displayed his victims' lightsabers around his belt as trophies of his conquests. His unorthodox fighting form and mechanical enhancements gave him an edge in close-quarters combat, and his strategic ingenuity and flawless cunning rendered him almost invincible against the Jedi.

In the final stages of the Clone Wars, Grievous orchestrated a daring strike against the heart of the Republic. His flagship led a fleet of massive warships to Coruscant, where an immense battle raged in the upper atmospheres of the capital world. The fighting had gone on long enough -- one way or another, this strike would lay the foundation for the end of the war. Grievous was determined to be victor, and hoped to add the lightsabers of the most famous Jedi warriors -- Anakin Skywalker and Obi-Wan Kenobi -- to his grisly collection.
