- Awesome Music: The theme songs written for Astray for the SD Gundam G Generation series, including Lowe's theme Junk Guild: Red Frame and Gai's theme Serpent Tail: Mission Commence.
- Also T.M. Revolution's Zips during the action sequence in the Red Frame animated short!
- Complete Monster: Ash Gray is an Ace Pilot for the ZAFT special forces and essentially a Serial Killer with a mobile suit. Joining the military solely to kill as many people as possible, Ash adds a doll to his collection for each victim he kills, seeing these as his trophies. Assigned to hunt down Lacus Clyne, Ash destroys the Erudou space station and comes up with the idea of gunning down civilians to catch her attention, a plan that is protested by a ZAFT officer shortly after. Opening fire against the Junk Guild's ship, Ash gladly mocks Lowe's optimistic beliefs regarding the human nature, confessing to killing people simply because he enjoys it. Left in command of a Kill Sat, the Genesis Alpha, Ash can only think to himself how much damage he will be able to inflict with it. Falling directly into Earth Alliance territory, Ash is assimilated into the Extended program and returns as one of their scouts, using a computer virus to alter the Genesis Alpha's targeting data, nearly causing it to fire at Earth. Breaking free of the brainwashing, Ash causes the Genesis Alpha to destroy an Earth Alliance base before committing suicide.
- Crazy Awesome: Lowe Gear. This is the guy who fashioned a katana for his Gundam, and later forged a 150 meter version of it, just because he thought that would be awesome (the sword is mounted on the side of their ship, and requires special equipment to wield). He also once attached a BuCUE head to the Red Frame's hand for use as an impromptu double beam saber (this being the only reason he bought the BuCUE head at a junk auction).
- Ensemble Dark Horse: Shiho Hanenfuss, the mute Ensemble Dark Horse of SEED anime, has much more role in Astray. Though still a relatively minor character, she actually speaks in the manga (she would have spoken in the anime, mind you, but her voice actress bailed). Naturally, her extended role made her even more popular.
- Fashion-Victim Villain: V.V., the Dandy antagonist in Destiny Astray R; he prepares a fake treasure to try and trap Lowe, but his sense of honor wouldn't let him just place an empty box so he put in a set of his clothing, which he considered a great treasure. When Lowe opens the box, he finds it contains a purple jacket, matching pants, and a pair of pointy-toed boots; he and 8 instantly agree that whomever this "Pirate King" was, his fashion sense was pretty tragic.
- Les Yay: Very briefly when the Professor and Erica Simmons greet each other, with the sparkle-and-flower imagery coming up during their embrace. The manga's SD comic strip lampshades the author's intent when the two go somewhere private for some "catching up to do", leaving Lowe and the rest of the gang to assume that they're gonna do it, and then subverts the trope as it turns out that the two are actually catching up on their study of Orb's mobile suit development.
- It's Popular, Now It Sucks!:
- Like the HGUC Unicorn kits, Some foreign Gunpla builders is starting to get tired to Bandai releasing the MG Astray variants (Astray Noir, Astray Turn Red).
- The entire series is this as well, as the sequels continue to milk its popularity by giving more Astray variants.
- Toy Ship: Prayer and Kazahana
- What Do You Mean, It's Not Symbolic?: The Testament Gundam is almost always equipped with the Divine Striker backpack. Thus, its proper name is "Divine Testament".
