YMMV / Gravion

• Best Known for the Fanservice: While Masami Obari is no slouch in regards to fanservice, this is one the shows everyone will bring up when you mention him and "sexy girls" (beforehand, he put a similar style to Animated Adaptation to a certain SNK game (and directly designed in one of the games with similar style)). Most people remember the cute maids and the ridiculously busty beauty that is Mizuki. In case of Mizuki, sometimes it made people forget that she has a lot of Hidden Depths beneath her busty Cool Big Sis Femme Fatale schthick. Even beyond being a spy.
• Crazy Is Cool: Sandman IS this trope. He's a Cultured Badass who sounds awesome giving cheesy Transformation Name Announcement statements, does death defying stunts to pull people's asses out of hot water (with the same amount of tension you show waiting for toast to quit toasting), and has (in dead seriousness) led his Meido squad in powering up his Super Robot with freaking karaoke! His most illustrious Moment of Awesome involved a ping pong game, bath slippers, and over the top Calling Your Attacks ("First, Disappearing Serve!" "Next, Burning Smash!" "Okay, this is something that even flies can stop. Slooooow Serve!". And he scores all of them.), and frankly, he just wouldn't be awesome without the crazy. He lives in a giant castle that's really a space ship filled with hot maids who can fight (at least one is a robot), he's a super intelligent scientist who invents giant mecha in his spare time, can kick ass, makes a horse do physically impossible stunts, is obscenely rich, and does cool poses just for the heck of it. Also helping this is that he's voiced in Japan by Show Hayami, who gives Sandman the most epically suave voice ever while being squarely good from day one.
  Sandman: BOW DOWN TO OUR HEAVY METAL GOD! GRAVION!
  Raven: Sir, what was that?
  Sandman: I have always wanted to say that.
• Ensemble Dark Horse: In some areas of the internet Faye is very popular.
• Fan Nickname: Gravion Trombe for Sandman's God Σ Gravion, which looks like the original Gravion in the black and red color scheme of Ratsel Feinschmeker.
• Fridge Logic:
  • (Hugi having only one control panel and one off-switch for the Genocidron System, as well as not just broadcasting pictures of his niece Leele Zeravire to them all, which is said to cause them to shut down automatically.
    • You expect an insane Omnicidal Maniac to do things logically?
  • When Ayaka dons the Raven mask, her boobs shrink for no reason. While it does cover the fact she's a woman, maybe it's due to Form-Fitting Wardrobe, but is there ever any explanation about why her boobs suddenly burst out when she removes the mask? And she wasn't even doing anything to get any concealments off, either...
    • It's the mask. The picture of the previous Raven (Luna's father) looks exactly like the current Raven (Ayaka). The mask also changes the wearer's voice. Safe to say the mask would be able to alter her bust size if it can alter her hair, voice, and musculature.
    • It's an Obari production, so it was likely done for fanservice
• Funny Moments:
  • The final episode of the first season. The EFA, after gathering data from Gravion itself and Mizuki's spying, finally managed to unveil a new Super Robot that will defend Earth from Zeravire. During its unveiling day, before the President could even state its name... A Zeravire promptly dropped down on it and completely crushing it.
  • The first episode of ZWEI begins with suddenly the Gran Knights dressing as maids (and once again, Eiji and Touga are cross-dressing finely) and becoming Servants. Luna scolds Eiji that this is all his fault... cue flashback that Eiji was losing badly against the maids in strip mahjong and all he's left was just his panties. And thus, in a desperate attempt for a second wind... Eiji betted on the whole Gran Knights, without their permission, to become servants for a day. It's unreasonable, but a man never goes back from his word, and he boasted that they're going to witness a comeback! ... Which naturally didn't happen.
• Growing the Beard: First season was a normal fanfare Super Robot show, where everything is done as cliche as possible and there was no plot point that got concluded, leaving things in the mystery. Zwei resolved those, including concluding Eiji's search for his sister, but adds up more to the stake, namely Eina's robotic nature, Mizuki being a government spy, Touga's psyche being a Child Soldier taking its toll on him, both Sandman and Leele's relations with the Zeravire leader. It was by the second season that the show gained its own identity.
• Ho Yay: Eiji and Touga, mostly because Touga doesn't quite "get" normal relationships and seems oblivious to the girls' affections; meanwhile, a falling-out with Eiji makes Touga shut down completely until Eiji brings him out of it. Eiji sneaking Touga out into the city plays a bit like a date, Eiji's rescue of Touga results in Romantic Ride Sharing on a Motorcycle on the Coast Road, and their endgame mecha link together in a... rather suggestive way. In the epilogue, after he accidentally catches a bridal bouquet, Touga ignores the expectant blushes of both Luna and Leele and innocently proposes to Eiji; when he's corrected that marriage is between men and women, Eina adds that in some countries, same-sex marriage is OK too... and Luna's response wasn't that of disgust, she's also okay with Touga marrying another guy... she just took offense that the guy he chose was Eiji.
• Les Yay: Heavily implied with Ayaka and Mizuki, to the point where the latter is shown getting completely wasted over her missing 'friend' and even hits on Raven and (half-seriously) Eiji while drunk, likely because they remind her of Ayaka, as Eiji is Ayaka's younger brother and Raven is Ayaka in disguise.
• Just Here for Godzilla: Klein Sandman alone is reason to watch this show; see Crazy Is Cool above.
• Moe: Sandman commands a legion of Moe young maids! And aside of that, Leele also provides the more subdued Moe type, the docile Shrinking Violet kind that fuels the urge to protect.
• Narm: Very localized version, but hearing the characters gushing with joy over an amusement park called "Grand Island" is unintentionally amusing for those familiar with the relatively ordinary city of Grand Island, Nebraska.
