In Sonic the Hedgehog: Mobius 25 Years Later, she is 16 years old. In Sonic Univers: Mobius 30 Years Later, she is 21 years old
yes. he has a daughter named Lara-Su. he names her after his wife (Julie-Su) and his mother (Lara-Le). Lara-Su is also the future guardian after Knuckles
Lara-Su the Echidna is the future daughter of Knuckles and Julie-Su. she is the guardian of Mobius 25 years later and Sonic Universe 30 years later. she has spikes, like her father, but she can retract hers at will. she has the ability to fly and use chaos control as well as her father can. like her mother, she is a tomboy but has no cybernetics for when Knuckles became Chaos Knuckles he made Julie-Su fully organic (as seen in a flash back in 25 years later but was never seen in the comics of their present time). Lara-Su is also said to have feelings for Argyle the Crocodile (Vector's son)
Some say that he marries Julie-Su the Echidna, but it is unknown.
she is 16 years old in both the Knuckles the Echidna and Sonic the Hedgehog comics. in Sonic the Hedgehog 25 Years Later (where it shows everyone in their future reference) she is 41 years old. & in Sonic Universe 30 Years Later she is 46 years old
Julie-Su first appeared in Archie Knuckles the Echidna issue 4. but her first appearance in Sonic the Hedgehog was issue #53
Julie-Su the Echidna is a female echidna. she is a pink, tomboy echidna who use to be in the Dark Legion with her two half siblings, Lien-Da and Kragok the Echidna's (who never liked her since birth). when Julie-Su was just a young child her half brother and half sister murdered Julie-Su's mother and made it look like an accident. Julie-Su's father (also Lien-Da and Kragok's father) wasn't able to look after Julie-Su on his own so he sent her to a new family but she remained in the Dark Legion. she then met some years later in Knuckles in "Knuckles the Echidna" issue #4 and became a member of the Chaotix and after a few issues became Knuckles' love interest and soul mate. she later marries Knuckles in the future and has a daughter with him. but Julie-Su no longer knows nothing of her childhood or her parents because Lien-Da wiped her memory some years back. Julie-Su, like everyone else in her family in the Dark Legion, had one of her dread locks and left arm replaced with cybernetics
Yes in the Archie comics it shows that Julie-su is most likely Knuckles' girlfriend in the future they have a daughter named Lara-su but in the future they're not married
Julie-Su the Echidna is not dead. she never died. her only appearance(s) were in the Sonic comics; Knuckles the Echidna, Sonic the Hedgehog, Sonic Super Special, StH 25 and 30 years later. but Julie-Su never died. she just, sadly, never appeared in anything other than the comics so people slowly forgot about her
she is 4,000 years old
