General Aguila is one of the ancient Stone Generals who first appeared in the movie TMNT, as one of the film's main antagonists and the leader of the Stone Generals. He, along with his three brothers and sister in arms, led a massive army to conquer the world in ancient times. To help accomplish this end, Aguila's brother in arms Yaotl opened a dimensional portal using a wheel-like artifact and an alignment of nine stars, releasing thirteen monsters into the world. The monsters decimated his army and their current opponents, a Central American civilization. In addition, opening the portal turned Aguila and three of his siblings in arms into stone, and left Yaotl a flesh and blood immortal.
