"Star Wars Rebels" season 3, episode 6 is expected to see the arrival of Captain Rex.

The previous episode offered a great deal of revelations, and spoilers for the upcoming episode titled "The Last Battle" suggest that Captain Rex will finally arrive to reunite with the team.

Captain Rex is a clone trooper captain who is described as someone that should not be taken too lightly. A veteran in the army, he is known for his valuable service with Anakin Skywalker during the Clone Wars. His technical code is CT-7567 and his broad range of experience goes beyond the field, as he is also well-trained for combat. In fact, he started young when he trained and prepared to become a high-ranking leader for the Republic's army.

While little is known about "The Last Battle," fans expect that the entry of Captain Rex will make the episode an action-packed one. As he reunites with the team, many believe that his alliance with the rebellion will work to the team's advantage when the time for the battle comes.

Meanwhile, some reports claim that the upcoming episode will also see Grand Admiral Thrawn as he makes the best use of his deceptive ways in fending off the rebels. It can be recalled that in the previous episode, Hera and Ezra finally saw Thrawn. This villain does not immediately use weaponry during battles, but uses reverse psychology technique in beating his opponents. Fans will see more of him in "The Last Battle."

"Star Wars Rebels" season 3, episode 6 airs on Oct. 22 on Disney XD.
