Shardicole

Shardcole is the non-binary ship between Shard and Nicole from the Sonic the Hedgehog fandom.

Canon
The only known issue where both characters appear is in Sonic Universe #50.

After Shard was rebuilt, he joins a secret spy team. In their first interaction, they are playing holo-chess in Nicole's handheld computer. During their time together Nicole states that Shards visits her often, then starts a conversation between the two. While they are talking, Shard says "I don't get how someone could code some as perfect as-" then gets interrupted by a unexpected message that Metal Sonic is destroying the town and holds Antoine hostage. Shard then flies off to save him.

During their battle he mumbles "If I'm going to protect her... everybody... sorry 'brother', but I've got to put you down."

When Shard is lying down helplessly after his battle he calls for help. As he was ending his call, he was about to say something personal to Nicole, but was cut out.

Fanon
