She is not in sonic adventure time. Yet she is considered one because she is not in any of the Video Games.
no and they never will, julie-su is a archie comic character. plus they already finished sonic x.
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 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
knuckles love 3 girl call rouge the bat from sonic x, Sonia the hedgehog from sonic underground and julie-sue the echidna from sonic comic but he did not like shade the echidna and tikal the echidna
in the game I think Rouge the bat. in the comics I think Julie Su the echidna
Knuckles and rouge have canonically feelings for each other , that's an official statement by Sega Japan. Julie Su is a non canon character and non official. Her relationship with knuckles is a non canon event and like in "another dimension", not in the real world of Sonic. Shadouge is a fan ship not a real couple.
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
they first kiss in Knuckles the Echidna issue #28. they're also seen kissing in Sonic the Hedgehog issue #200
julies a women
a lot of people THINK that knuckles and rouge should be together, but its REALLY supposed to be knuckles and tikal.
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
due to their height, they weigh lighter than humans their age. but not most of the girls actually revealed their weight except for cream, julie-su, etc.
