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: Not the Frost brothers (who are Smug Snakes at worst) but New Earth Federation leader Lord Fixx Bloodman and SRA leader Seidel Rasso. They don't survive the final battle.
Nomoa Long as well. See the Gundam subpage of Complete Monster for a full list of his atrocities.
Crowning Moment of Heartwarming: Garrod REPEATEDLY breaking out of his cell just to go get flowers for Tiffa. And then he returns to his cell.
The first ED (it's in English and it features that guy who started and finished "Voices That Care", dood!)
A lot of the BGMs that play whenever battle is joined. The one that plays when the Satellite Cannon is deployed is notably epic. That track is called, surprise surprise, "Satellite Cannon".
The Scrappy: Olba Frost, the younger Frost, is ferociously bashed by fandom for supposedly being a male Yandere with a brother complex. Even his voice actor hates him - the role even gave him an aversion to "Nii-san."}.
It was already a fan-favourite long before Z came around: ever since its debut in Alpha Gaiden it's been one of the more popular of the A Us among the SRW fanbase.
