NightmareXCross Headcannons

Headcannon #10, 11 & 12

They’re both overly protective of each other. The thought of something happening to either of them will have the other person freaking out and flying to the rescue. Cross is more likely to publicly fall on his face in the process, while Nightmare has more of a stalker approach

Chara is like the crightmoss’ family pet.

Nightmare sneaks up on Cross on a regular basis just for kicks. Cross tries to do the same thing back sometimes, but it never works
