Lara-Su (alternate reality)

Lara-Su is Knuckles and Julie-Su's daughter from an alternative future timeline. She first came to Mobius Prime to prevent her father from being killed by Echidna Security Team leader Constable Remington, as her mother explained that was how Knuckles had died in their timeline. She proved unsuccessful, though she managed to thwart a Dark Legion plot to assassinate Julie-Su. When she was transported back to her timeline, her mother explained that she'd gone back to an alternate universe instead of back in time, and finally revealed that Knuckles was still alive in their reality, and was the evil leader of the Dark Legion. The two then prepared to embark on a mission to defeat him. She has red fur, violet eyes, pink hair with traces of purple and peach skin. She wears black vest lined with blue, red shirt matching her fur, blue gloves with black cuffs, black boots with blue toes, blue socks and black glasses.

Trip to Mobius Prime
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. (StH: #106, #107)

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-Su was left confused as Remington was not responsible for firing the shot that killed Knuckles. She then overheard Lien-Da talking with the Dark Legion sniper Syntar about taking out Julie-Su and the Mitre. She knocked out Syntar just before he had a chance to fire his shot. Lara-Su realized that she may not have gone back in time to have saved her father, and that perhaps there was a reason her mother did not talk about her younger years. At that moment, Lara-Su began to transport back to her own future reality, despite wanting to stay longer and gain some more answers. (StH: #108, #109)

Upon arriving back in her own time, she confronted her mother and learned from her that the Knuckles in their timeline 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-Su to confront her deranged parent. The last to be seen of this Lara-Su was her following her mother into an uncertain conflict to defeat Knuckles. (StH: #109)

Abilities
As Knuckles's daughter, Lara-Su commands Chaos energy through a link to the Master Emerald. This allowed Lara-Su to travel back in time and paralyze an Echidna Security Team officer. She also commands Knuckles' strength, and has fist spurs similar to his, which she can retract at will.
