McAngus was stunned by his own flashbang after it was kicked back at him by Binary. He was then incapacitated by Tachyon's blasts and knocked out, only to be taken into custody shortly after.
No one is really sure if the mercenary named McAngus is actually named 'McAngus', or whether it was a nickname given to him that just stuck. He has never corrected anyone - at least not verbally. He tends to correct people with gunfire and violence.
