- Awesome Music:
- The soundtrack has a mix of jazz, blues and pop. Bonus points for the composer who happened to be the saxophone player and member of Yoko Kanno's The Seatbelts (of Cowboy Bebop fame).
- The "Hone Kudaketemo" is great homage to Nina Simone's "Feeling Good" and is used as the end credits of Episode 6 which is really fitting.
- Darkness-Induced Audience Apathy: This series milks the War Is Hell trope for all its worth. The story is pretty Grimdark even for Universal Century standards, as both sides do quite a few horrible things in order to prevail.
- Ensemble Dark Horse: Bianca is quite popular among viewers do to her fun personality and all around sexyness. She's also one of the Federation's more competent female pilots. Her introduction in Bandit Flower is her being thrown around A Baoa Qu by a Bigro, and using her GM's beam saber to destroy it. And she'd already had seven kills before! Bianca later pilots a Guncannon Aqua and holds her own against the much bigger and more powerful Gogg. She even rescues Io and his Atlas Gundam from sinking into the ocean, after her Guncannon suffered heavy damage!
- Hilarious in Hindsight: Episode 6 unknowingly answers the question of how amphibious mechs are expected to function when the water is all frozen over in Gundam Build Fighters Try.
- Narm: Daryl's reaction to one of his comrades' apparent death in Episode 2 (eng. dub) can be a bit hard to take seriously when you remember the Heavy Rain glitch.
- Rooting for the Empire: At least in the first season of the anime, it's a lot easier to feel sympathy for the Zeon side when Daryl is a kind-hearted soldier just doing his duty for his homeland. And on the Federation side, Io is a Politically Incorrect Hero who repeatedly mocks Daryl's prosthetics, and is a Blood Knight who gleefully engages in Mook Horror Show. Averted in the second season, where Io is portrayed more positively, and both sides share an enemy in the absolutely repugnant South Seas Alliance.
- Unexpected Character: The Zanny, an early prototype GM made mostly from salvaged Zaku parts that previous only appeared in an obscure StarCraft-clone PC game known as Gundam Tactics: Mobility Fleet turns up in the hands of the South Seas Alliance (rechristened the Dahle in the anime version, possibly due to rights issues with the game's publisher).
