Knuckles does have feelings for rouge and he kind of shows it......
BUT I HATE ROUGE! SO DOES MY FRIEND!
No.
Shade the Echidna and Knuckles the Echidna are both characters from the popular Sonic the Hedgehog series. It is not believed that Knuckles loved Shade in any way.
Nothing has been released confirming or denying Knuckles' feelings towards Rouge.
As of yet, Rouge has not been stated to have feelings for any character with the exception of her crush on Knuckles.
No, just Knuckles.
No they aren't, mostly Knuckles and Rouge are seen as enemies. Rouge does in fact have a crush on Knuckles but Knuckles has doesn't have the same feelings for Rouge, Rouge says that he's cute when he's angry but Knuckles feels disgusted over that.
No, but in the episode of Sonic X: Cracking Knuckles, it showed that he had a bit of a crush on Amy when Knuckles was trying to go away and leave them alone after settling with Eggman, but Knuckles doesn't really have that much of feelings for Amy since in the comics he has a girlfriend (and soon wife) Julie-su, partner in games Shade, and for fans Tikal, and of course Amy loves Sonic which is very obvious, and Amy has more feelings for Sonic than anyone and anything in the world
No, the brass knuckles are not part of any weapon schematic
Yes; you can squeeze something really hard when you feel the need to crack your knuckles.
No. There is no evidence that cracking your knuckles or fingers will lead to any adverse consequence (not even arthritis).
he dates and partners (not marry) Julie-Su in the comics and they have a daughter together. but in the game "Sonic and the Dark Brotherhood" it has been said that he had feelings for Shade the Echidna, but she only appeared in that one particular game. Knuckles and Sonia the Hedgehog had feelings for each other in Sonic Underground but it was never stated that they actually started dating. it has also been stated by SEGA that he likes Rouge the bat, but that still has yet to be confirmed. he and Princess Sally Acorn also may have developed feelings for each other in the early comics but those feelings didn't last very long
