I always wondered where we came from. Luckily, Chase put the pieces together for me. My father fought for what he believed, that bionic humans are superior. And when his beliefs were challenged by a non-bionic human like Davenport, he fought back. And that's why I'm going to carry along his legacy. See, you took away our leader and tried to pretend nothing ever happened. I think it's time for a little payback.
Sebastian is shown to be hot-headed and very rebellious. In Rise of the Secret Soldiers, he is shown to be very cocky and underestimated Chase, causing his defeat. He was influenced by Adam's laid back attitude and as such, mostly did not get along with Chase. Sebastian had a tendency to pick fights with Chase, having antagonized him at least several times.
After being freed by the Triton App, he came across as being too trusting, often taking Adam's advice literally or answering the door to what could have been random strangers or government agents. By Adam Steps Up however, he did develop some common sense, as he wondered why his brother Bob took Davenport's jet.
Along with his bionic brother, Spin, he avoided getting named by Donald Davenport by picking his own name. Before that, Davenport planned to name him Julio.
Sebastian does care for his brothers and sisters, as he was concerned about Bob, and knows him quite well.
After Chase revealed the truth about who Sebastian was before being released from the Triton App, he secretly swore to take out Mr. Davenport for revenge forvery destroying Victor Krane. Just like his father, he believes normal humans are inferior.
After the incident in Bionic Rebellion, his abilities have been removed due to the chip removal. All of his bionics on this page are former. He may get them back in the future.
Every Bionic Ability: He revealed he unlocked all of his hidden abilities.
Super Strength: Just like Adam, he is stronger than an average human.
Super Speed: Just like Bree, he is very fast and can keep up with other bionic soldiers, and even Bree.
Laser Pitchfork: Similar to Chase's Laser Bo Generation, his Laser Pitchfork is very similar, however, it is red in color and is shaped like a pitchfork.
Geo-Leaping: Like all (or most) of the other bionic soldiers, he can geo-leap at will.
Physical Attributes: Sebastian also possesses higher reflexes than a normal person.
Molecularkinesis Sebastian can manipulate the molecules around an object, giving him a form of telekinesis. This ability will also allow him to move things with his mind, just like Chase.
Energy Transference: Like Leo, all the bionic soldiers have energy transference. This ability can absorb any type of energy source and it can be used medically. With the rest of his brothers and sisters, aka the other bionic soldiers, Sebastian used his Energy Transference to heal Leo. However, he and each person gave a fraction of their life energy so that they wouldn't suffer the same side effects Leo did when he saved Donald's life.
Bionic Beacon: In Adam Steps Up, he is shown to have a bionic beacon as he tried to search for Bob. He can also send messages to his other brothers and sisters, even those who weren't awakened for the battle.
Electrokinesis: In the episide Bionic Rebellion, he has demonstrated that he can create and manipulate electricity. He shot the Lightning at Chase and Bree. It is one of his many hidden abilities.
Pyrokinesis: In the preview of Bionic Rebellion, he shoots a large amount of fire at Chase. This is the ability Chase unlocked for him. It is also one of his many hidden abilities.
Energy Projection: In the preview of Bionic Rebellion, he shoots energy from his body. This was also shown when he projected energy a few times at Adam, Bree, and Chase. It is one of his many hidden abilities.
Heat Vision: In Bionic Rebellion, he shoots lasers from his eyes. He can also control the intensity. It is one of his many hidden abilities.
Bionic Chip Overload: In Bionic Rebellion, he uses all of his bionic abilities to try to destroy Adam, Bree, Chase, and Leo. When doing so, he overloads his chip causing it to fry.
Glitches
Bionic Chip Overload: In the episode Bionic Rebellion, Sebastian unlocked all of his abilites and he malfunctioned.
Trivia
Sebastian revealed he unlocked all of his hidden abilities. This caused him to fry out, just as Douglas said would happen if he unlocked all of Chase's hidden abilities.
Sebastian was the bionic soldier on the security footage presented by Douglas.
Out of the three siblings, his abilities are more related to Chase's.
In Rise of the Secret Soldiers, he lost a battle against Chase, but he does not remember since every single one of the soldiers forgot their memory after their Triton App got deactivated.
He resides in Davenport's Davenport Bionic Academy in the capsule dormitory, just like all of the other soldiers.
He's formerly known as S-3, but he changed his name to Sebastian in the episode, First Day of Bionic Academy.
Sebastian thinks Bree is cute. (First Day of Bionic Academy) He will follow any instructions as long as Bree is involved, though he doesn't seem to pay attention to what he's doing.
Sebastian turned evil after finding out about Victor Krane and what happened to him.
Sebastian claimed that he is the most advanced student out of the whole students, even though he's only Advanced Class (Orange), while the Expert Class is the highest (Red). In First Day of Bionic Academy, some students where shown to be in Expert Class already, which means all of the Expert Class students in that episode were demoted or Sebastian was just over exaggerating. But it is possible that he is the best student now , since he gets promoted to Expert (Red) between Unauthorized Mission and Bionic Rebellion.
At the end of Unauthorized Mission, when the students and the Lab Rats have left, Sebastian states that because the Lab Rats took away his father (Victor Krane), he would take away their father.
He shows some similarities to Marcus, the main antagonist of Season 1 and part of Season 2.
After finding out about his father's fate, he pretended to befriend the Lab Rats, but is actually planning to take out Donald Davenport. However, he was a true friend to the Lab Rats before finding out the truth.
Similar to Leo with Marcus, Perry is the only one who knew Sebastian was evil.
Prior to becoming evil, Sebastian seemed to be the de facto leader of the bionic soldiers, caring the most about his 'brothers and sisters' and knowing each of them (such as knowing that Bob is colorblind).
