First off, I just love how Omega said, "I wanted to destroy them!" He legitimately sounded like a child. "But daddy, I wanted to destroy them! Waaaaa!"
DISCLAIMER: DO NOT TAKE THAT OUT OF CONTEXT, I WAS MAKING A JOKE
Second, it looks like the Commander's full name from the Archie Comics, Abraham Tower, is canon, it's his official name now.
Lastly, judging from the credits, I assume Abe and Omega were played by Roger Craig Smith, meaning that once again, Roger had to fill in for Omega.
