The princess of the planet Galaluna, Ilana is sent to Earth alongside Lance and Octus for her protection against Modula's forces, disguising themselves as students in Sherman High School. She is compassionate and well-intentioned, but her naivety of human ways causes the student body to label her a "doofus." Ilana and her armor system Corus is the "heart" of the Sym-Bionic Titan.
Action Girl: Less aggressive than the guys, but she can and will fight when the situation calls for it.
Anime Hair: Seriously, how does her hair manage to stay up like that? And from the looks of her dad, it apparently runs in the family.
The one time you actually get to see her hair down is very briefly when the cheerleaders and she fall into the school pool. Cut to the next scene, and her hair is automatically back up again.
The hairstyle appears to be a Galalunian cultural thing. Baron in episode 8 has this hairstyle as well, as do several Galalunian background characters.
Barrier Warrior: Corus, her armor system, is equipped with force fields.
Beauty Is Never Tarnished: Strongly averted in Episode 13, then again briefly at the beginning of Episode 16 when she gets herself dirty from climbing down a well.
Episode 19 shows that shes doesn't always look so fantastic in the mornings.
Body Horror: Happens during episode 13, "The Demon Within". The burns from her injury look gruesome, but the transformation sequences are quite a bit more graphic, going to the point of showing Ilana, still technically thinking and acting as herself, seeing her reflection in a puddle, and discovering that part of her head has opened to reveal her brain.
Fragile Speedster: Her Corus armor seems to be like this, yet it's sturdy enough to survive a falling building and a stomping from a false Manus unit unscathed.
Frickin' Laser Beams: Corus can shoot a beam capable of destroying pretty much anything. This gets shown off in episode 11.
The Pollyanna: Definitely the most upbeat and optimistic member of the group.
Powered Armor: Her Corus unit is like this and is only slightly larger than an adult human by a foot or so.
The President's Daughter: Modula wants Ilana killed so that there is no one in his way to take the Galalunian throne and no one to inspire hope in the people to rebel against him.
Princesses Prefer Pink: A fair portion of her outfits consist of either pink or purple. Even the screens inside her armor are pink.
Royals Who Actually Do Something: When Galaluna was at peace, she did a lot of diplomatic and humanitarian work, as well as copious rescues of trapped-in-a-well pets.
Spock Speak: Similar to that of Starfire (even though she's voiced by Raven). This lasts for only the first few episodes, however.
Spoiled Sweet: Ilana is obviously used to the finer things in life, but she doesn't let that get in the way of saving the day when evil rears its head oh-so-often.
Unlimited Wardrobe: She's worn four different outfits in a single episode.
A Galalunian soldier and Ilana's bodyguard. Lance is labeled as a "bad boy" at school when he unintentionally draws all the girls' attention. He is not one to back out of a fight and is very protective of Ilana, easily mistaking anything as a threat to her. Lance and his armor system Manus is the "body" of the Sym-Bionic Titan.
Badass Driver: Just look at what he does in episode 5.
Beauty Is Never Tarnished: Somewhat averted in the rather Squick-inducing interrogation Xishi pulls on him and when the audience clearly sees him get bruised for good measure by the G3 interrogator.
Chick Magnet: Every girl at school practically worships the ground he walks on, but he can't actually work up the nerve to pursue the one he actually likes. The one time he asked she turned him down, but that was more because of his choice of locale rather than denying him personally.
Fish out of Water / No Social Skills: In his own sort of way, especially when he considers anyone who so much as lays a hand on Ilana as an enemy.
Geeky Turn-On: Mike Chan's car causes his "circuits to pulse."
Genre Savvy: He knows that any time Ilana gets excited about something it probably won't end well and in "A Family Crisis" he flat out states that nothing good will come from leaving to rescue Solomon.
"Why is it that everyone agrees that I'm right but we're going anyway?"
Jerk with a Heart of Gold: He can be pretty intense when it comes to protecting Ilana, evidently shown in the second episode, but he's well-intentioned and will try to make up for his wrongs — such as destroying the robot that he accidently led back to the neighborhood and getting Ilana the snow globe she was admiring from the furniture store.
Interestingly, Lance often avoids the Conflict Ball with Ilana.
As well as the fact that as the episodes go on, Lance is slowly mellowing out (or at least he's not as Hot Blooded as he used to be).
Nice Job Breaking It, Hero: Lance has more than once managed to create quite the mess due to his insensitivity and quick-tempered nature.
One-Man Army: Lance, to the point that the Galaluna Military seems to think his mere presence would be enough to turn the tide of the war they've already lost.
Self-Made Man: He had some support from the king and General Modula, but other than that he was pretty much on his own.
Shirtless Scene: So far, he's had more fanservice than Ilana!
Shrinking Violet: If "Disenfranchised" was any indication, he doesn't like being the center of attention very much and even shrinks away at Ilana's accidental announcement of his playing in a band.
Of course he my just be Genre Savvy enough to know that once Ilana starts making a big deal out of something it's bound to end in disaster.
A bio-cyberneric robot sent alongside Ilana and Lance. Octus's hologram disguises include "Newton" when he's in Sherman High School; and Ilana's and Lance's "Dad" outside of school. He is intelligent, but is considered a nerd by Sherman High School students. Octus is the "mind" of the Sym-Bionic Titan.
Came Back Strong: Is brought back to life by the head of G3 in the series finale. Not only can Titan be formed again, its power increased greatly along with having gained the ability to fire powerful energy beams from its limbs.
Do-Anything Robot: So far, Octus has been very versatile. He can even generate solid cash (and other objects) by apparently converting it directly from energy. This may be the same matter-replicators used to make the Titan's weapons.
Flying Brick: Not only can he fly, he can get hit by a truck on the freeway without being hurt. The truck crumbles from the impact, while Octus doesn't even flinch.
Genius Bruiser: He could probably beat Lance in a fight if he wanted to.
Heroes Want Redheads: With Kimmy, though she seemed to be attracted to him first.
I Will Protect Her: Most fans seem to forget that he has the same bodyguard mission as Lance, he's just more calm about it. May also extend to his girlfriend Kimmy.
The Kirk: Originally started out as The Spock until he later gained emotions.
Lightning Bruiser: In addition to being able to move faster than the human eye can see, Octus is also strong enough to punch monsters through walls with relative ease.
Master of Disguise: But he frankly doesn't put that much effort into it when we know for a fact he could. Aside from the fact that his bulk never changes, his "dad" persona is essentially his "student" aged up appropriately. He's shown the ability to alter his appearance into a much thinner form, so apparently he just doesn't feel like it.
Mundane Utility: Octus is super-strong and super-fast, and will use all his might and skill to... throw snowballs.
Mysterious Past: Exactly how he came to be isn't entirely clear. We at least know Ilana's father was doing some touch-up work just prior to the invasion, but that's it.
Not Distracted by the Sexy: Kimmy's dance in "Lessons in Love" fails to convince Newton to do her homework for her.
Opposites Attract: Newton developed a completely unexpected romance with the not-so-ditzy sexpot cheerleader, Kimmy.
Protagonist-Centered Morality: Octus is the most guilty of this out of the three, which makes sense because his programming dictates Ilana be protected first and foremost. He doesn't want Lance stopping crimes only because it attracts undue attention, and was perfectly fine with Lance driving a car without a license (and would have made him one if asked).
By the events of "A Family Crisis" he seems to have moved past this mindset, agreeing with Ilana to respond to Solomon's distress call as it is the right thing to do, much to Lance's annoyance.
Real Men Wear Pink: Literally. He wears a pink apron and matching oven mitts when he cooks.
Ridiculously Human Robots: Octus has made the point several times that he's not an average robot whenever this issue comes up.
Robot Buddy: Although Ilana and Lance don't seem to see him like this.
Secret Identity: He has TWO of them; Newton and 'Dad' Lunis. How Newton fits into the Lunis family is highly ambiguous.
She Is Not My Girlfriend: He says this exact line when Lance teases him about Kimmy in "Lessons in Love". Then he ends up kissing her and they've been dating ever since.
Sizeshifter: An extension of his shapeshifting ability, allowing him to grow to giant proportions. The team probably couldn't form Titan if he didn't have this power.
Super Speed: Octus displays this in Episode 6, going fast enough to be invisible to the naked eye and whip up a strong breeze, yet not fast enough to cause a sonic boom. He doesn't even have to move his upper-body to boot.
Team Chef: He seems to be the only one in the group who knows how to cook.
Team Dad: In the literal sense, as he disguises himself as the team's father at home. Plays the trope straight, too.
Tin Man: In "I Am Octus." It was inevitable, really.
Unexplained Recovery: After spending episode 19 dead, he's brought back to life by the head of G3 in episode 20 and this is pretty much his explaination.
What Is This Thing You Call Love?: Subverted - he understands the concept but doesn't feel it with Kimmy (initially, at least). Instead, he feels 'happy' around her (sounding more like an unusually self-aware teenager than a robot).
General Modula
Voiced by Don Leslie
The driving force that caused Lance, Ilana, and Octus to flee Galaluna, Modula is a sort of dictator who controls a group of aliens called the Mutraddi. Because he is too busy conquering Galaluna for himself, Modula sends a giant monster every so often to kill the princess and stop any possibility of rebellion against him.
Authority Equals Asskicking: One episode displays him putting down a rebellion platoon using nothing more than his bare hands without really trying. Counts during his pre-Big Bad days, too: he deactivated two Manus armors standing upright by himself in an instant.
Roaring Rampage of Revenge: His whole motive seems to be to get revenge on the King for abandoning him on the Mutraddi homeworld.
Solomon
Voiced by Tim Russ
An enigmatic individual affiliated with a group known as the Galactic Guardians. His ambitions, motivation, and alignment remain to be seen, although to date he has typically served only to play as the voice of reason against the heavy-handed tactics of General Steel. Both his fighting style and the technology he uses are Galalunian in origin, a mystery that has yet to be explained.
A decorated military officer whose unit is the first to encounter Ilana and Lance after their decent to Earth. He has deep contempt for the Titan once it becomes known, and openly encourages people to assume it to be a menace. He's also stubborn as a mule, refuses to listen to the advice of his subordinates, and never takes responsibility for his mistakes. Openly detests Solomon.
BFG: His mecha is armed with a large number of these. But the one it uses as a Finishing Move is connected to its arm and can completely vaporize a giant monster in one blast.
Chronic Hero Syndrome: His speech during the televised debate over whether the Titan is a friend or a menace hints that part of the reason he so strongly detests the Titan is that people consider it a hero, and not people like him.
General Ripper: Steel's violent obsession to stop any aliens tends to endanger his men and everyone around him.
Shows during his mecha's first battle. His fighting style is far more agressive than the Titan's and tends to cause a great deal of damage.
Good Is Not Nice: He's not really evil, and takes his job as a soldier seriously... but he's probably the least pleasant earthling we've seen in the series so far.
Harmless Villain: Starting to fall into this, especially compared to Solomon and Modula.
Not So Harmless: Not anymore, he finally decided to even the playing field and get himself his own giant robot, The Hammer.
The captain of Sherman High's cheer squad. When she is first introduced she behaves like a stereotypical mean and shallow popular girl, but it's really all just an act. She first reveals her true nature to Newton and, to everyone's surprise, falls in love with him. The two have been dating ever since and so far she has no idea that he's really a robot. She is similarly oblivious to Lance and Ilana's secret identities, though their behavior makes her suspicious at times.
Brainless Beauty: Greatly deconstructed; Kimmy has very little confidence (initially) of her intelligence because people see her as this trope, and a good talk with Octus helps her realize that she didn't need to follow the stereotype.
Obfuscating Stupidity: Reveals to Newton that she believed she's a ditzy airhead because society says so. He convinces her otherwise, and is indeed much brighter than she realized.
