These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Gosterro, a Gradosian officer who takes We Have ReservesUp to Eleven - his only real joy is killing people, the more defenseless the better, and his lust for blood is such that he often kills his own men just to get a kick out of it. Logic tells him that killing his own men might prove detrimental to him as well... but he's so Ax-Crazy that he just doesn't care sometimes. To cement his Complete Monster status, in fact, he often refers to his victims as "prey" or "meat" and gets all tingly at the prospect of killing people in the most gruesome of ways. Truly a monster, if there ever was one in such a dark Real Robot series. And his hilarious death of getting stepped on by a giant mech? WELL EARNED.
Lawful Evil: Gresco is Type 1 ["will keep our order and laws at all costs, even if we have to fuck the world over"], Le Caine is Type 2 ["with a personal code of honor, but an evil bastard otherwise"].
The Gradosians cross the line in the first episode already by brutally massacring the defenceless exchange students and personnel. And they just keep on running from there!
Gosterro in particular keeps having his own episode-after-episode following his debut: Eiji takes Gusten, one of Gosterro's wingmen hostage and threatens to execute him, hoping that Gosterro would call off his men and retreat. Gosterro calls his bluff, then later brutally kills Gusten himself after Gusten tries to kill Gosterro in revenge for his complacency. When the other wingman, Roberia, hears Eiji accuse Gosterro of killing Gusten, he questions Gosterro about it, who just ignores Roberia and implicates himself. When Roberia tries to capture Gosterro and bring him before a court trial, Gosterro kills him in cold blood with no hesitation. In the next episode, when Gale's SPT squad is going to chase after Eiji, Gosterro hijacks another SPT and kills the Gradosian soldier inside, laughing about it. Posing as Gale's wingman, he then tries to backstab and kill him after Gale questions Eiji about the deaths of Gusten & Roberia and then casually kills Gale's other wingman. At this point Gosterro has only been on the show for 6 episodes.
Most Annoying Sound: Gosterro's voice in general, specially his Evil Laugh. It's like Masashi Hirose was told to voice Gosterro with the most annoying, nerve-wreaking voice tone he could come up with.
The Scrappy: Arthur, who has clearly mistaken abject stupidity for comic relief. He becomes slightly more bearable in the 1999 arc, if only because, as a now-chubby member of the elite who ineffectually tries to collaborate with his friends in La Résistance, he's in the show much less.
