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: General Draconis. Mass genocide, starving the surviving humans of Venus, personally responsible for Nara's parents deaths, and betrayal of Phaeton while he was relatively sane. A stark contrast to GeneralShiva whose in charge of Earth.
Doctor Ketzer, who turns a tribe of Amazonian People into half-plant monsters, and injects Nara Burns with the same stuff in an attempt to get Able Squad to destroy a city. Worst of all, he's a Karma Houdini since the show didn't get to finish.
Crowning Moment of Awesome: Quite a few, but one of the big ones was the Resolute II taking on Phaeton's flagship, using a cloaking device to get close enough to deliver broadsides at point blank range.
Foe Yay: Even though he's asexual, Phaeton seems to spend a lot of time obsessing over Marsh.
Hilarious in Hindsight: The Executive Producer of the show once compared Exosquad to Gundam, noting that both invoked World War II campaigns. Several of the voice actors in Exosquad would go on to dub various Gundam series.
Nightmare Fuel: If you stop to think about it, quite a bit for a saturday morning cartoon. Aside from the normal carnage of war (shooting and explosions and what not), we see characters get exposed to hard vacuum, starved half to death, put in cargo containers and launched towards the sun, and the effects of the Graf Shield, which crushes starships (and their occupants) like soda cans. That's just the first season, by the way. The second season gets much worse.
They outright call what Draconis is doing to the humans a genocide.
What an Idiot: Not putting Melee Weapons onto the Exoframes to deal with the Neo Warriors and Neo Lords, thus the Exoframes being mostly helpless whenever they get to Melee Range (This may be due to Executive Meddling).
