Asoc is the Captain of Factory Beta.
Biography
Asoc was produced by Lefty specifically for the purpose of piloting his Factory Beta. Lefty did this because he didn't trust any of the native Toa, Matoran, or other to pilot it efficiently. While the Factory was in its earliest stages of production, Asoc was made from the same batch of protodites, so that he would have a connection with the ship, allowing them to be 'as one', so to speak.
