Noriko Takaya

• Ace Pilot: Becomes one over the course of the series.
• Action Girl
• Adorkable
• Ascended Fangirl: In the science lesson shorts, she reveals that she's a big Getter Robo fan. Also, she gets mentored by the actual Getter team in Super Robot Wars Alpha.
• Badass
  • Badass Adorable
  • Badass Armfold: Arguably the Trope Codifier in Japan.
  • Took a Level in Badass: Quite possibly one of the best examples. Compare her performance in episode one with that in episode four.
• Smash Sisters: With Kazumi.
• Break the Cutie: Breaks pretty quickly in Episode 1, and breaks again in episode 3-4, before Taking Her Levels In Badass.
• CALLING YOUR ATTACKS: Enough over the course of just six episodes that she became Goddess of the trope.
• Cute Clumsy Girl
• The Danza: Voiced by Noriko Hidaka.
• Expy: Of Hiromi Ouka, considering that Gunbuster started as an Affecionate Parody of Aim for the Ace!
• Gainaxing
• Hot Blooded: Even more so when you consider that she's the basis for Simon.
• Iron Woobie: Wasn't iron at all when things started out, but come episode 4....
• Red-Headed Heroine: Although it's a really dark shade that borders on brown sometimes.
• Rousing Speech: Gives one to Kazumi in episode 5, combined with a verbal Bright Slap.

Kazumi Amano

• Action Girl
• Badass
  • Heartbroken Badass: In episode 5, when she has to leave Earth for a mission and by the time she gets back, he'll probably be dead from his illness. Subverted when they return to Earth after victory and he's still alive.
• Smash Sisters: With Noriko.
• COOL BIG SIS: Goddess of the trope. She's actually referred to as "oneesama" more than by her own name!

• May-December Romance: Is in love with Coach Ohta, who was an officer on the Exelion with Noriko's dad.
  • Hot for Teacher
• World Of Cardboard Monologue
• You Gotta Have Blue Hair

Jung Freud

• Author Appeal: Was apparently named by Hideaki Anno. Yes, that one.
• Faux Action Girl
• Foreign Fanservice: She's from the Soviet Union, judging by her mecha.
  • Or, judging by the name, on loan to the Soviet Union from East Germany (like Sigmund Jähn in Real Life).
• Expy: If Kazumi and Noriko are Reika and Hiromi, Jung is most likely their Ranko.

Koichiro "Coach" Ohta

• Badass
• Drill Sergeant Nasty
• May-December Romance: With Kazumi.
  • Hot for Student
• Expy: Of Coach Jin Munakata
• Norio Wakamoto
• Playing Against Type: Wakamoto hadn't actually been typecast yet, but Ohta doesn't have any of the Villainous Large Ham that Norio Wakamoto has since become so known for.

Kashiwara

• Alpha Bitch: In the first episode.
• Heel Face Turn
  • Defeat Means Friendship: Gets her butt kicked at the end of the first episode and promptly cleans up her act.
