8. Rick Flag
Being the leader of the Task Force X, Rick Flag could be considered a fairly important side character within the DC universe. It could be argued that he is a main character, but his role often takes a back seat to the likes of Harley Quinn, Deadshot and the rest of the team. He earns a spot here for the fact that he’s a fairly interesting character whose connection to the Enchantress plays a huge part in Suicide Squad. With him dedicated to recovering June Moone from the grips of remaining Enchantress, Rick has a hidden agenda that he keeps from the rest of the Squad. His personality is that of a loyal soldier and his back and forth with the team is entertaining. These things add up to earning him this spot.
