- Arc Fatigue: The fight with Kary-08 had to be split up into three episodes. Keep in mind that the series is only seven episodes long, so nearly half of the series was spent on it.
- Awesome Music: Quite a few pieces, mostly from the later episodes.
- Big-Lipped Alligator Moment: Hank's cameo in episode 3, where he high fives Omega and body slams a Mook before heading off.
- Funny Moments: Xero's reaction to discovering his and Omega's Evil-Knockoff robot doubles.Xero: It's our own action figures! WE'RE FUCKING FAMOUS, MAN!"
- Tear Jerker: Omega's death at the end of 4-3. Made especially sad by Xero's refusal to kill him, the two having become Fire-Forged Friends.
