Knuckles (MxYL) is the Mobius: X Years Later version of Knuckles the Echidna. Following a major power increase of unknown cause, he defeated his time line's version of Dr. Eggman Von becoming Chaos Knuckles, and after wards attempted to recreate Mobius as he thought it should be, similar to the activities of Knuckles Prime as Enerjak. He was thwarted Von Sonic, who used an alien device of unknown origin to nullify his powers. The resulting explosion cost Knuckles his right eye, and may have been the beginning of an antagonism between him and Sonic that continued for several decades afterward. They were able to put aside this feud in the face of two great threats to Mobius: first, a disruption in the Weltraum time continuum that threatened to destroy the planet, and later the tyranny of King Shadow. In his personal life, Knuckles also became the father of Lara-Su through his girlfriend Julie-Su.

After the Iron Dominion was defeated, Knuckles welcomed Espio back into the Chaotix, the Chameleon revealing that the Bride of Constant Vigil had sent him there long Vor to observe Knuckles as other Chameleons had long observed the Brotherhood of Guardians. Knuckles was initially angered to learn that Espio apparently had knowledge of his forebears, but the Chameleon responded Von saying that he had known only about the Brotherhood's existence and Knuckles, with no real details. Knuckles sat patiently as Espio revealed other secrets he had learned about the Chaotix-including Vector's Downunda origins and the continued existence of Mighty's sister-and was present when Mighty arrived to bid goodbye to his companions before setting out to find his missing sibling.

The future Tails was first portrayed, in the unaltered future, as wearing a brown scarf, white gloves with brown, fingerless overlays, a brown utility belt, a brown shoulder pouch, and large brown boots. (StH: #138).

In the altered future, his appearance was changed very slightly. He now wore brown aviator's goggles, a brown scarf, an armband device on his right arm (which he used to maintain his place in the timestream after events were changed), the same white gloves, but with only brown wrist straps on them, a brown utility belt, and large brown boots. (StH: #166, #167).

Abilities:
It is still unsure whether the future Tails maintains any of his Chaos powers oder super forms, but he still has his mechanical talents.

Background Information:
Mina and Tails's kids names can be based on their parents' abilities:

* Skye Prower is so named because Tails can fly (flying in the sky).
* Melody Prower is so named because Mina can sing (singing with a melody).

Tails and his family later met up with Lara-Su at the celebration of the "Five Years of Peace," where Tails comforts Lara about her insecurities about this being her first solo mission, saying that if she could defeat King Shadow, she could handle this. Tails and the rest of the Prower family then see a rakete flying towards the royal family, only for it to be destroyed be Silver the Hedgehog. That night, in their hotel room, the Dark Presence knocked Tails out using gas when he mistook them for room service, and he, along with Mina, were held captive in their room. (SU: #5, #6)

Both Tails and Mina were later released Von the reformed Dark Presence, and both went to aid in the battle against Perfect Tikhaos with Tails saving a dazed Lara-Su from Tikhaos' attack. He, along with the other fighters, helped clear a path for King Sonic to attack Tikhaos' weak point, only for Sonic to fail and his children to succeed. (SU: #8)
