Knuxouge

Knuxouge is the het ship between Knuckles and Rouge from the Sonic the Hedgehog fandom.

Games
While it was never shown how the two met, in their first appearance together (and Rouge's first appearance in general) in Sonic Adventure 2, they were fighting over the Master Emerald. During their fight, Dr. Eggman stole the Emerald. Knuckles broke it in order to avoid the doctor from utilizing its power. The incident angered Rouge and tortured Knuckles for the act. The two decided to search for the Master Emerald shards on their own.

They fought each other on their next meeting. Following the battle, Rouge fell, and Knuckles saved her. Rouge got angry, claiming Knuckles only saved her to hold her hand, which Knuckles denied. Rouge then gave him the Master Emerald shards she had found, claiming that they stunk like echidnas, which made Knuckles wonder why she even went after the Master Emerald in the first place.

The two later teamed up with Sonic, Tails, Eggman, Amy and later Shadow to save the Space Colony ARK from falling.

In Sonic Heroes, their teams encountered in Lost Jungle and ended up in a fight as both were trying to defeat Eggman first. Later, when Metal Sonic grew stronger, the teams (along with Team Rose and Chaotix) teamed up to defeat him. After the battle was over, Rouge mentioned getting treasure and left, after which Knuckles ran after her.

The two teamed up in Sonic Rivals 2 in order to find the Master Emerald.

The two were among the guests to attend Sonic's birthday party in Sonic Generations. Before the Time Eater attacked, Knuckles and Rouge were seen talking to each other with chili dogs on their hands.

Sonic X
Throughout the show, there are many iconic moments where Rouge hits on Knuckles. It's hinted in the episode "The Volcanic Venture" that Knuckles may have returned feelings, since when Rouge went to look for Chris, he smiles shyly at her and waves goodbye. This can indicate that because they were alone, he didn't have to hide his feelings from her, due to embarrassment. It's also hinted when Rouge asks Knuckles about his feelings, and he turns away and denies it.

Fanon
Knuxouge is an extremely popular ship. Its most notable rival ships include Shadouge (for Rouge) and Knuxikal (for Knuckles). On AO3, it is the most written ship for Rouge and the second most written for Knuckles, the latter behind Sonuckles.

It is most of the time shipped alongside Sonamy, Shadaria, or Silvaze. This ship has gone up in popularity since the Sonic X fandom came to life. This is most popular towards the Pre-Super Genesis Wave Archie comics and Sonic X fans because of canon romance in both. There are some extremely competitive ship wars against Shadouge because of it's popularity.
