- "I'm taking charge."
"Whatever you say, Dave – Dennis – Danno..."
- ―Denal, taking charge
Denal's first act of heroism was to be one of the only survivors after General Grievous attacked his unit. Only he, Rex, and Ahsoka Tano survived. Denal naturally assumed this meant he was going to be one of the main characters. Denal was wrong. He survived the episode, but his recurring role was cut short later in season 2, when Cad Bane killed him and used his armor to hide among the other clone troopers. Sort of like Face/Off, but with clone armor.
He also showed up in some video games. He was one of the troopers with not a lot of hit points, so you really had to work hard to get him to survive the level.
