Conia

Colnia is the het ship between Cole and Vania from the Ninjago fandom.

Season 13: Master of the Mountain
When Cole and Vania both meet, they stare at each other, making Lloyd seem worried that they like eachother. Later, Lloyd warns Cole that Vania may not be what he thinks, but Cole says that he doesn't like her that way and that Lloyd was just thinking about Harumi. Later in the season when Cole sees a Geckle the ninjas think it isn’t real but Vania mentions that it was her imaginary friend and she wondered if it was real. Then they went to the cave where it was and they saw more creatures like it. Cole stayed and told Vania to call for help. Later in the season, Vania pretends to be the Ninjas so that the King (her father) won't find out. She mentions that he is the leader and master Wu is shocked when she says this.

Season 15: Crytallized
During the Crystal Zombie apocalypse, Cole, alongside Vinny, and Blazey Hyper Speed, drive off to the NGTV broadcast Tower to send a distress call Queen Vania. When they got to the tower, Cole starts to record his message, but unfortunately, the communication tower was knocked out, Cole thinks that the message didn’t reach to Queen Vania. Vania helps Cole and the other defeat the Crystal King/Overlord's zombies. In the end, they share a hug.
