HikaruCool and collected leader of the Exo-Force team. He is competitive and prefers to work solo, which gets him in troubles at first.
- Cold Sniper: Most of his battle machines have good ranged options and he's a loner at first.
- Cool Shades: His minifigure gives him orange shades, but his Animesque design from the comics only has them be a mainstay during the jungle arc with him only wearing them once before then.
- Headbutting Heroes: With Takeshi, at least early in the comics.
- Ineffectual Loner: Is very reluctant to work as a team at first, but slowly learns to trust in others.
- Teeth-Clenched Teamwork: Early in the comics, his loner status makes it pretty hard for him to get involved in teamwork missions.
TakeshiFierce and serious guy who lives for one thing - to smash the robots into tiny pieces. He used to be a miner at the shouthern peak of Sentai Mountain before the robots rebelled and he was separated from his family. While he has destroyed more robots than any other pilot, but his ruthlessness makes him unpredictable in battle.
- Attack! Attack! Attack!: While he can and has been able to came up with pretty awesome plans Takeshi seems to like strategies like this much better. This is even lampshaded by him:Takeshi, when taken to the labs by Sensei Keiken: But why'd you bring me here? Ryo's the techie in our group - I'm more of a blunt object.
- Curtains Match the Window: Has both green hair and eyes.
- Disney Death: Is defeated by Meca One and disappears for a bit before Hikaru finds and saves him.
- Roaring Rampage of Revenge: Takeshi is driven by the robots capturing his family. He gets mostly over this once they are rescued by Hikaru.
- Stay in the Kitchen: While he doesn't display this trait in the comics, the tie-in books have him act hostile towards Hitomi for this reason, saying that he thinks that it was a mistake to put her in uniform even as the Golden Tower's guard. After they have to work together to get the next code however, he admits that she's a pretty good pilot and defends her when Sensei Keiken is furious with her for disobeying his orders.
- "X" Marks the Hero: An x shaped scar on his jawline.
RyoExo-Force's head mechanic. He is a genius when it comes to repairing and designing battle machines. Speaking and working fast, he's extremely resourceful and valuable member to the team.
- Adorkable: Oh, yeah. Somewhat socially awkward techie who talks to his battle machines, daydreams about becoming a hero and has an adorable blush. That doesn't stop him from being extreamly efficent in about everything he does.
- Bunny-Ears Lawyer: Has a habit of thinking his battle machines as if they were alive ( espesially Uplink, the first one he designed and built for himself ).
- Combat Medic: Ryo usually gets smaller support machines, but does just as well in a tank or the fairly awesome Blazing Falcon.
- Distressed Dude: Briefly gets captured by the robots.
- The Smart Guy: The mechanic of the team, and really passionate about working on the battle machines.
Ha-Ya-ToLaidback jokester who loves flying more than anything. He copes with war by turning it into his own personal action ride, but that also makes him take unnecessary risks in battle.
- Distressed Dude: Almost got captured by the robots during the Golden City Era, Hitomi rescues him.
- Fragile Speedster: He usually pilots small and fast battle machines that can't really take a hit. However, they are very good for dodging and harassing bigger and slower robot battle machines.
- Hot-Blooded: He views his battles as if they're games, and he's enthusiastic about it.
- Lightning Bruiser: Ha-Ya-To later gets to pilot Aero Booster, which is said to be THE fastest battle machine in whole series, in addition of having considerable number of missiles and laser guns mounted all over its gigantic engines.
- Out of Focus: During the Sentai Mountain arc he gets very little screentime despite being one of the four main characters. This changes during the Golden City arc thou.
Sensei KeikenMentor and leader of the Exo-Force team. Stern and wise leader, he is responsible for creating Meca One.
- Badass in Distress: Gets kidnapped by Meca One.
- Big Good: Is the leader of the Exo-Force team.
- Cool Old Guy: His old age doesn't stop him from being the leader of the Exo-Force team. He also had one moment of defeating a robot by acrobatically jumping behind it and turning the switch off.Sensei Keiken: "Never underestimate an old man, my metal friend."
- Overprotective Dad: Towards Hitomi, who he refuses to let pilot a battle machine because he doesn't want to lose her. The reason he allows her to become the guardian of the Golden Tower is that it is unlikely for any danger to reach there (he ends up being wrong, but Hitomi can take care of herself just fine), and refuses to let her pilot the Golden Guardian even if it is designed to protect said tower.
- Passing the Torch: Before being kidnapped by Meca One, he manages to leave a message promoting Hitomi as leader.
- Stay in the Kitchen: Sensei Keiken never allows Hitomi to be a pilot after losing her parents because he can't bear the thought of losing her, it was only until Ha-Ya-To needed rescuing and Ryo being put out of commission does she finally get her chance.
HitomiSensei Keiken's granddaughter and one of the mechanics in Ryo's team. Brave and determined, she becomes a pilot against her grandfather's wishes.
- Adaptational Badass: The only set that she comes in and the comic included in said set's instruction manual paint her as a Faux Action Girl who lacks a mech and doesn't get to see much action. The comics and tie-in books reassign the Blazing Falcon from Ryo to her and she's shown to be more than capable of taking care of herself.
- Big Good: Is promoted to leader after her grandfather's kidnapping.
- Boyish Short Hair: As a mini-figure, she uses the same hair piece as Hikaru.
- Early-Bird Cameo: Hitomi is first seen in the comic 23 as one of Ryo's techs, seven comics before we even get to know her name.
- Faux Action Girl: Hitomi is tried to be put as an Action Girl, and had the series continued that may have happened. But as it is, she appeared in one set with no mech to speak of. In the comics, however, she briefly pilots the Blazing Falcon normally assigned to Ryo.
- Hair Color Dissonance: At first her hair color was a navy blue, later comics have it more darker. As a mini-figure it's black.
- My Parents Are Dead: Sensei Keiken is her only parental guardian.
- The Smurfette Principle: Is the only female in the series.
