Red shows his calm and a very reserved bird and is quick to anger towards the other birds in Bird Island when they act clumsily towards him or getting angry for small things. Red's horrible temper sterns from being teased by fellow birds who are making fun of his thick brow when he was younger (As well as the fact that, as an egg, he was apparently abandoned by his parents and hatched alone in a Lost and Found bin) and also can't control when he is angry. When his mind isn't clouded by rage, Red can be surprisingly intelligent and perceptive. He was the first one to suspect that Leonard and the pigs weren't who they pretended to be and shouldn't be trusted. He tried to warn the other birds about this, but none of them believed him. As Leonard and the pigs steal their eggs and everyone apologizes to him for not listening to his words, Red is also a very serious and determined bird and has leadership qualities to teach the birds how to fight the pigs and to save the eggs. Red is also shown his bravery to protect the Blue Egg from Leonard as well as to avoid from being exploded by TNT made by Leonard during the fight as Red survives the explosion and the Blue Egg that he protected was hatched into three Blue Birds.
Red's ability is identical to his game counterpart in the first Angry Birds as he manages to break through Leonard's castle roof. He also has a wrestling fighting style where he does an Elbow Drop and a Giant Swing and lastly is to outsmart the enemy.
