Shadarine

Shadarine is the het ship between Shadow and Marine from the Sonic the Hedgehog fandom.

Canon
Shadow and Marine both originate from the games, but never appear together (excluding Marine the Raccoon costumes in the Mario & Sonic series). They do not meet in the Post-Super Genesis Wave Archie comics either.

In the very first issue of Sonic Universe, Shadow was fighting Metal Sonic in the Sol Dimension, but fell into water during the fight. He was rescued by Blaze and Marine. Marine offered Shadow a towel to dry. Shadow explained how he ended up in the Sol Dimension, after which Blaze and Marine told Shadow how they knew Sonic the Hedgehog. While Shadow and Blaze got along, Shadow was quickly annoyed by Marine.

The three found out that Metal Sonic was attacking Southern Island in his search for the local Dr. Eggman, and the trio teamed up to stop him. Blaze attempted to attack the robot, but it was no use. After the failed attack, Marine jumped on Metal's back and began hitting his head, but this did not work either. Shadow was unable to attack Metal Sonic when Marine was on the robot's back. But when Marine fell off, the black hedgehog tried to unsuccessfully convince Metal Sonic to disobey Eggman. Following this, Blaze and Shadow damaged the robot and sent it flying in the air. Marine used the cannons of her ship to destroy Metal.

The impact indirectly destroyed Shadow's only means of returning home, and asks Marine to build a boat. She replied that she "oversaw development" and Tails did the building. Eventually with Blaze's help he got possession of a Chaos Emerald. Shadow returned to G.U.N. headquarters through Chaos Control, presumably never meeting Marine again in later issues.

Fanon
Shipping the two romantically is very uncommon due to conflicting personalities. There is, however, a DeviantArt user called ShadRine, named after the pairing. It is so rare that there used to be only one fanwork of the pairing itself showed up with the "shadrine" tag.
