Lara-Su

Lara-Su is Knuckles' and Julie-Su's daughter from at least three possible futures. The first Lara-Su came from a future in which she believed her father to be dead, and came back in time to prevent Echidna Security Team leader Constable Remington from firing the killing shot. She proved unsuccessful, though she managed to thwart a Dark Legion plot, only to learn that she had traveled to an alternate past. In truth, her father had been long ago driven insane by Chaos energy and become leader of that future's Dark Legion. The second Lara-Su, of the Mobius 25 Years Later futures, has both parents but is initially at odds with her father, who refuses to allow her to become a Guardian. Eventually, he relents, only for that future to be warped almost beyond recognition by an alteration to history. Lara-Su and a few others recall the rightful timeline, and together fight the despotic Shadow the Hedgehog, Lara-Su herself ending the fight by imprisoning him with Chaos Control.

In the Present
Born in an alternate future version of Mobius, Lara-Su grew up thinking that her father Knuckles had been killed when she was younger, and became determined to undo that tragic event. Traveling to present day Angel Island, she arrived during the period in which all the inhabitants except for Knuckles, Julie-Su, and the Dark Legion had been teleported to the Twilight Zone by the Quantum Beam, Lara-Su was rather confused to find Echidnaopolis deserted. Her confusion multiplied when Chaos Knuckles, using his immense powers, undid the beam's effects. Lara found herself surrounded by the returned Echidnas, among them Remington-the very Echidna whom she had been told by her future mother, Julie-Su, had killed Knuckles. Deciding to go undercover until she could make sense of things, Lara-Su made the constable's acquaintance, claiming to be one "Jani-Ca." Almost immediately afterwards, she ran into her grandmother and namesake, Lara-Le, and then the past versions of her parents. She was quite astonished to see Knuckles in his green form, which had apparently never happened in her knowledge along her timeline. Regardless, she continued in her quest to protect Knuckles from being killed during a meeting between Dimitri and the Mitre of Angel Island as the Dark Legion and Echidnaopolis negotiated reunification. Lara-Su arrived just in time to prevent Remington's attack on the true assassin, whose shot-aimed at either Dimitri or the Mitre-was caught by Knuckles, who then faked his own death. Heartbroken, Lara decided that it was time to return home, though she did prevent a Legion sniper working for Lien-Da from killing the younger version of her mother. Just before teleporting, Lara realized that something was wrong: if Knuckles had died before he and Julie had become life partners, she wouldn't exist. Upon arriving back in her own time, she confronted her mother and learned from the future Julie-Su that the Knuckles she remembered was now leader of the Dark Legion, having absorbed a massive amount of Chaos energy and gone insane. Julie had hidden the truth from her daughter by saying he was dead, but the time had come for Lara to confront her deranged parent. The last to be seen of this Lara-Su was her following her mother into an uncertain conflict.(StH: #106-109)

Unaltered Future
In the first Mobius 25 Years Later future, Lara-Su was born to an unmarried Knuckles and Julie-Su, and raised as close to being an ordinary Echidna as she could be. Due to his own bad experiences in the position, Knuckles refused to allow his daughter to begin training to become a Guardian, even though she wanted to follow in his footsteps. This continued until she was sixteen and had her Unveiling, a ceremony in which adolescent female Echidnas are introduced to adult society. Lara continued badgering her father to let her become a Guardian, leaving them both irritable to the point where Lara attacked her cousin Rutan in a school class that they shared. Despite her discontent with her father's wishes, Lara-Su agreed to go through with the ceremony, sharing a dance with Knuckles and with Vector the Crocodile's son Argyle. Afterwards, she spoke with her mother about her father's stubbornness, but Julie-Su supported Knuckles in his decision. Unbeknownst to either of them, Knuckles was meeting with Rotor of the Kingdom of Acorn, who had discovered that Mobius was in grave peril unless Knuckles and Sonic, who had long ceased to be on good terms and argued constantly when together, put aside their quarrels and joined the resources of Angel Island and the Kingdom.(StH: #131-138)

Blissfully unaware of the events unfolding around her, Lara-Su was more concerned with her social life. As the royal family prepared to visit, she learned that Sonic and Sally Acorn's son Manik had a crush on her, the thought of which horrified her-especially the idea of Rutan finding out and using it against her. She begged her aunt Lien-Da, with whom she was quite friendly, to swear secrecy, to which Lien-Da agreed with amusement. Soon afterwards Sonic, Sally, Manic, and Lara-Su's best friend from off Angel Island, Sonia, arrived for their stay with the Guardian family. While Lara and the other youngsters tried to enjoy the get together with some other friends on the island-Espio the Chameleon's daughter Salma and an Echidna named Riki-Le-their parents found themselves reeling with what Rotor and his Dark Legion counterpart, Cobar, had to tell them about Mobius' impending doom. Oblivious, Lara and her friends-together with Sally and Julie-enjoyed a sleepover. Finally, though, Knuckles relented to her request for Guardian training after paying a visit to the grave of her grandfather, Locke. Before he could begin training her, though, Knuckles said he had an errand to run-in fact, he was accompanying Sonic on a mission that would hopefully stabilize Mobius and prevent its destruction. Showing that she was her parents' daughter, Lara-Su stowed away aboard the vessel that her father and the king boarded, only to disappear into thin air just as Sonic was being sent back in time.(StH: #139-144)

Altered Future
Whatever Sonic did in the past drastically altered the future that Lara-Su hailed from. Shadow the Hedgehog replaced Sonic as Sally's wife and the king of Mobius; Manik and Sonia ceased to exist; and Knuckles served as Shadow's enforcer with the Dark Legion backing him and Lien-Da serving as the king's advisor. Despite these negative consequences, Lara-Su found herself being trained as a Guardian, which she greatly enjoyed as her powers continued to develop. However, the arrival of Miles "Tails" Prower, her father's childhood friend who had also protected his memories and those of his family from the temporal alterations, brought an end to her acceptance of this timeline. When Knuckles seemingly refused to help Tails, Lara-Su agreed to, missing her now non-existent friends and wanting to end Shadow's regime. The two found "King" Sonic homeless in an alley in the Echidna city of Portal, only to be caught and arrested by the Dark Legion. Knuckles then revealed that the whole thing had been a setup: his own memories of the original future remained, and he had been planning to overthrow Shadow for some time. To her dismay, Lara-Su was left with the task of escorting an injured Rotor to safety while her father, Sonic, and Tails launched their attack to defeat Shadow and rescue Sally. When Sonic was defeated in battle as her father escorted Sally to safety, Lara-Su stepped in to confront Shadow herself. After a brief but intense contest in which Lara suffered an injury from Shadow's Chaos Spear, she was able to imprison him using Chaos Control. As Sonic and Sally were reunited, she then left on the arm of her proud father. (StH: #166-167)

Personality
Both versions of Lara-Su possessed exceptional determination and dedication, no doubt taught to them by their respective fathers. In either form, Lara often finds herself utterly confused by a number of situations, and she has a rather vulnerable nature at times. This has led her parents in both futures to mislead her or deny her certain privileges, but in the end they did it out of love. Mobius 25 Years Later's Lara-Su is also shown to have her parents' gung-ho fighting style and somewhat smug attitude.

Powers
As Knuckles' daughter, Lara-Su commands Chaos energy through a link to the Master Emerald. This allowed the first version of Lara-Su to travel back in time and paralyze an Echidna Security Team officer. In the second Mobius 25 Years Later, she has been trained by Knuckles in the use of her powers and thus is even more proficient, capable of matching Shadow's use of Chaos Spear and Chaos Control and even surpassing them. It is unknown if she commands Knuckles' strength, but she does have fist spurs similar to his, which she can retract at will.
