Lyle Dylandy
Informations of Mobilesuit wiki.
Season 1
Lyle is first introduced as Lockon's unnamed younger brother early on in season one, where he is shown carrying a bouquet of flowers to place on his family's grave as his brother watches him from behind a tree. He does not make another appearance for the remainder of the season; however, he is mentioned by name in Lockon's dying soliloquy, in which Neil remarks that the world of tomorrow would be the world in which Lyle would live in. Seiji Mizushima posed the question in an interview "But, which one is Lockon?", which implies that because we do not know which Lockon is hiding, we do not know which one is responsible for the rift between them.
Lyle is shown in the Gundam 00: Gundam Meisters PS2 game to be watching the mourning Tieria at his family's grave in the year AD 2311; this time, however, he is the one spying from behind the trees. This may have lead Lyle to become suspicious of Neil's fate, somewhat contradicting his later surprise at hearing of his brother's death.
Season 2
In the post-credits scene at the end of the season two premiere, Lyle makes a brief cameo where Setsuna recruits him into Celestial Being to become a Gundam Meister just as his brother was. Setsuna approaches Lyle, revealing Neil's identity as a Gundam Meister and how he died for Celestial Being's cause, and begins referring to Lyle as "Lockon Stratos." While Lyle questions if Setsuna and Celestial Being want him to take on Neil's dying wish, Setsuna casts the notion aside and instead asks if Lyle wants to change the world like his brother. Leaving the decision for Lyle to make, Setsuna passes along information that the Federationfs security bureau would be embarking on counter-insurgency operations against Katharonfs European bases soon. Lyle (under the codename Gene-1) contacts Klaus Grado and his Katharon comrades to pass along information on the Federation's plan before joining Celestial Being and acknowledging himself as Lockon Stratos. His appearance shocks the entire Ptolemaios crew, especially Feldt Grace, who had taken a liking to Neil.
Despite having accepted the task of being a Gundam Meister for Celestial Being, Lyle's loyalties seem to lie first and foremost with Katharon but does care for his comrades in Celestial Being. Throughout the series, Lyle frequently contacts the organization, sneakily passing on top-secret Celestial Being intelligence in order to benefit Katharon; one example is in the mission to rescue Allelujah, in which Katharon worked with Lyle's information to take advantage of Celestial Being's presence and rescue their imprisoned comrades. While these actions do not seem to lead to lasting harm, given that both parties have one common enemy, it is not explicitly stated if Celestial Being considers Katharon as an ally to aid, and thus Lyle's duplicity may be unwanted. Lyle also contacts the Katharons when Celestial Being is in need of help as shown in episode 14.
When A-Laws attack Katharon's base, he heads off and destroys all of the A-Laws Automatons in anger and later attacked Soma Peries when they began retreating. After the attack by A-Laws, he along with the other Meisters to act as a decoy to distract them from noticing the escape of the remaining Katharon members. After the battle, Lyle and Tieria go to search for the missing Allelujah. He is surprised to see Allelujah and Marie kissing, but jokes that he "did a good job".
Lyle and Allelujah later rescue Setsuna and Tieria from Ali Al Saachez, who had survived Neil's attempted killing four years ago. Tieria reveals to Lyle that Saachez was his brother's killer; however, Lyle doesn't seem to be bothered by it, as he claims to not be as concerned with revenge as Neil was. Even when Setsuna reveals that he was a part of the terrorist organization that killed Lyle's family, he still refuses to avenge them, believing that the past cannot be changed, and to fight for anything but the future would be futile.
Later, Lyle plays a crucial role in the assault on the A-Laws superweapon Memento Mori by using Cherudim's shield bit system to protect the Ptolemaios II , which could not form a defensive field as it was using all its power to storm the Memento Mori head-on. After attacks from Tieria and the Ptolemaios II exposed its electromagnetic-field powered, light resonance chamber, Lockon finished the weapon off by sniping the exposed weak point, which effectively destroyed the weapon in a gigantic explosion.
During the mission to retrieve Veda, Lyle faces against the murderer of his family, Ali Al-Saachez, as Neil did four years ago. In the midst of the battle, Lyle successfully manage to damage the Arche Gundam and kills Ali Al-Saachez avenging his family and completing Neil's task.
