Terence

The Big Brother Bird (also known as the Giant Red Bird, Bordeaux Bird, Caveman Bird, Fat Red Bird, Juggernaut Bird, A380 Bird, fat bird, Big Red Bird, Power Bird, Terrence, Big Nuke Brother or Big Cardinal Bird) is one of the several birds in Angry Birds. It's described as the larger counterpart to the Red Bird, having much more strength. If is tapped or clicked while moving, it will result in a big whine. However it's more powerful than his little brother, the Red Bird.

Big Brother Birds are first introduced in the episode The Big Setup and are used for the majority of the episode, starting from Theme 9-1. It is the only bird that can easily smash through about one block of concrete, and it doesn't need a special ability to smash through all types of obstacles. Instead, it uses its weight to crush through objects. However, his strength varies depending on what block(s) he's used on, as a large square block will almost always stop the Big Brother Bird in its tracks.
