Badass Damsel: Got at least one moment to be this in the episode with the cactus monster.
She also forced the very, VERY creepy Harry to flee all by herself.
The Chick: The only female that doesn't kick ass on a daily basis. Instead she tries to make everyone get along.
Damsel in Distress: Justified, as she's pretty important to the one thing everyone's after in the series, and furthermore she is the one female member of the Outlaw Star crew who isn't a semi-immortal alien or an assassin.
Eating Optional: Even though eating isn't necessary to her vital function, she finds she enjoys certain foods, after being prompted by Jim to try some. She was even surprised to learn she could distinguish different tastes.
Shrinking Violet: Notably shy for a girl who spends most of her time doing her job naked.
Unusual User Interface: She isn't a navigator, but rather the navigation system for the Outlaw Star. This requires her to jump into some backlit chamber and remove all of her clothing for some reason. Notably, she always enters and exits the navigation chamber fully clothed, the stripping appears to be involuntary and automatic.
Can't Argue with Elves: Played straight, subverted, double subverted, and parodied. Aisha won't hesitate for one second in reminding you of her race's superiority, get into trouble due to her childishness, bail out the crew when brute strength is needed, and she's frequently in as much debt as everyone else due to destroying wherever she works in a pointless fight.
Cat Girl: The ears, the "nya," and the feisty attitude. She even turns into a tiger-thing!
Clothing Damage: Aside from when she gets blown up, she shreds her outfit when she turns into her tiger form.
Man Child: She has zero maturity and impulse control, often making Gene appear to be extremely mature in comparison.
Ms. Fanservice: Little clothing and lots of skin are pretty much her metier. And if that isn't enough, there is the Hot Springs Episode where she's displayed completely naked for a short moment. With visible nipples.
The Nicknamer: Aisha calls Suzuka "Suzu," which noticeably irritates the latter.
Also subjected to one, being on the recieving end of a #12 Caster Shell in episode 5. Probably just to prove how tough the Ctarl Ctarl really are. She's unscratched, sure, but there's some pretty serious Clothing Damage.
By all means, she shouldn't be in this series, but it's cooler that way
Do Androids Dream?: Parodied. Gilliam is programmed with a mental block that prevents him from questioning or meditating on his existence or purpose — so instead of contemplating his navel, he contemplates his inability to contemplate his navel. Meta.
Camp Gay: And is he ever. Not even the edited forCartoon Network version could tone it down note (though why would they edit this in the first place seems a bit hypocritical. Remember, this is the same channel that got away with showing a lesbian biker group on Cow and Chicken, a lesbian cat relationship on Courage the Cowardly Dog, and a gay male robot on Time Squad) to the point that Gene and Fred's relationship could be construed as "just friends." They might as well have removed the character if they wanted to tone the series down, but then that would have caused plot holes. Changing Fred Luo into Frieda Luo would have been an option, too, but DiC wasn't the company that translated and edited this for American TV (and plus, anime fans were fooled once by Zoicite).
Gayngst: Completely averted. Fred's too busy making Gene blush and stutter to even care that he can never have him because Gene is heterosexual.
Manipulative Bastard: His affection for Gene is genuine, but he has no problem using his boytoy for any number of dirty schemes.
Dissonant Serenity: Played extremely, frighteningly well with Harry, going from pleasant to lashing to apologetic to screaming to eerily calm to furious, all in episode 17 in his Yandere obsession with Melfina
Evil Counterpart: Both of them could qualify for different aspects of Gene. Ron is a cool, calculating fighter who plans ahead, whereas Gene is hotheaded and prone to making stuff up as he goes along. Harry, his romantic rival, is disturbingly open with his feelings for Melfina and pursues her aggressively, while Gene keeps his feelings for her hidden to the point of seeming uncaring.
Family-Unfriendly Death: Harry has his insides crushed by Hazanko, which is so brutal that it was edited out in the original Toonami version
Mood Whiplash/Mood-Swinger: What made Harry's stalking to Melfina very unnerving, is that he switches from caring to violent to unnaturally calm at sudden swings, leaving Melfina understandably scared out of her mind
Pet the Dog: The two brothers do genuinely love each other and Ron is particularly upset when it looks like Harry's been killed. We also find out that while his obsession with her was pretty far from healthy, Harry's feelings for Melfina were purer than they first seemed.
The Power of Love: It causes Harry to become a decent person by the time of his death
Wet Ware CPU: Much like Melfina, Harry can connect to the MacDougal's ship. It's part of the reason for his obsession with her.
Wild Card: They're willing to take jobs from any of the three factions, as long as it pays well. The Wild Card aspect REALLY comes into play when they finish a job for the Kei Pirates...only to start on a job they got from the Space Forces that involves killing said pirates.
Bad Ass: Although they appear less often then most villains, the group is undeniably powerful and up to the job.
Bigger Bad: We know practically nothing about Hazanko's superiors, the Tendo King and the Tempa Emperor. However, considering that Hazanko, who is no slouch himself, felt he needed something like the Galactic Leyline to take on either of them it seems reasonable to assume that they are bugnuts terrifying.
Dangerously Genre Savvy: When the Outlaw Star crew proves to be a threat, the first Hazanko sends to get rid of them is Shimi. Word of God states that Shimi was the most skilled of the Kei Pirates, second to Hazanko. Before he fights Gene Starwind it's implied he's going through a Heel-Face Turn. When Shimi takes on the entire Outlaw Star crew he administers a Curb-Stomp Battle. Victory in his favor, Shimi decides to botch his duel with Gene and use it as an opportunity to fake his own death and leave the Kei Pirates. Hazanko doesn't know of this plot but is very displeased that Shimi "failed" anyway. Needless to say, Gene Starwind and friends would have been toast if Shimi was serious about his mission.
Devour The Dragon: Hazanko eventually merges with the Geomancer—including Tobigera and the rest of the crew.
Anti-Villain: By the time he faced off with Gene, Shimi expressed his exasperation in killing people and went as far as to throw the fight and fake his death to permanetly cut his ties to the Kei Pirates.
Badass Normal: Shimi appears to be the only member of the pirates lacking either sorcery or supernatural powers, but is arguably the one who comes closest to killing Gene and the rest of the crew.
Universe's Strongest Woman: Iraga entered a tournament for strongest person in the universe/galaxy and has a pretty good chance of winning. She beat the four time reigning champ less than twenty seconds.
Improbable Weapon User: Hanmyo being a master of "Space combat with cats" certainly invokes this trope. Ultimately, it means she pilots a grappler ship with two detachable arms, each piloted by a super-intelligent cat.
Informed Ability: Tobigera's a member of the Anten Seven, Hazanko's elite group of assassins, but his first attempt on the heroes was pure comic relief during the Hot Springs Episode, and after that he never gets a chance to prove himself.
He's also supposed to be a master of disguise, but never gets a chance to prove it. You'd think wearing an evil-looking mask all the time wouldn't do much to disguise you, though.
Casual Danger Dialog: For most people, the idea of Ron McDougal holding them at gunpoint would have them shitting bricks, especially if he was blaming them for Harry being dead. Not Khan though, he just stands there calmly stroking his beard, while only mildly perplexed by why Ron's blaming him. What makes it even funnier is his response:
Gwen Khan: (matter-of-factly) "Now that's utterly preposterous. It's not even logical."
Chronic Backstabbing Disorder: Has a habit of riding on the coattails of anyone who can get him closer to his goal, then ditching them once they've taken him as far as they can.
For Science!: In the end, all he wanted was to know the answer to all the mysteries of the universe. Which is foreshadowed, when he briefly discusses Melfina with Ron and Harry McDougal.
Ron: (astonished) "You mean, Melfina's too great a mystery, even for you, Professor?"
Gwen Khan: (frustrated) "Yes, yes! That's it precisely! Oh, to think that there are so many mysteries my brilliant mind can't fathom!"
Gwen Khan: "Indeed, I did, though I have no idea what you intend to do with it. Of course, I'll have to ask you to be careful with it, since I'll need it back. It was quite expensive, and a fine piece of craftmanship, if I say so myself."
Wild Card: For much of the series, it's hard to tell whose side he's really on, since he teams up with Gene, the McDougal Bros., and even worked with the Kei Pirates at one point, prior to the start of the series. No surprise, he was in it for himself the entire time.
