Frisk Kid

Frisk Kid is the non-binary ship between Frisk and Monster Kid from the Undertale fandom.

Neutral Route
Monster Kid and Frisk first met in Snowdin Town near a Christmas Tree. Monster Kid assumed Frisk was a kid just like them due to Frisk wearing a striped shirt. However, they did not notice that Frisk was in fact a human.

Monster Kid and Frisk met frequently in Waterfall, where Monster Kid talked about how cool their role model, Undyne, was. Monster Kid was unaware that Frisk was the human Undyne was looking for, and was jealous due to Frisk getting her attention.

When Monster Kid found out Frisk was a human, they tried to insult the human in a reluctant attempt to become enemies, but felt bad about it and left. As they were leaving, they tripped and were about to fall off the bridge as Undyne was approaching. The human could make one of four choices. If Frisk chose to save Monster Kid or run away, Monster Kid remained friendly with them (in the latter case, it was due to Monster Kid assuming the human was running to get help from others). If Frisk chose to run to Undyne or let the kid fall, Monster Kid started to hate humans.

True Pacifist Route
Monster Kid was among the monsters who cheered Frisk on during their face-off with Flowey. Due to this, Monster Kid's SOUL was among the ones absorbed by Flowey, turning him into Asriel, and used to break the Barrier.

After the Barrier was broken, Frisk and Monster Kid met again in Snowdin Town. If Frisk had chosen to save Monster Kid earlier, Monster Kid told them they no longer considered Undyne great and instead had a new idol, likely Papyrus.

Genocide Route
Monster Kid approached Frisk despite Undyne's warnings not to. Although scared, Monster Kid stood up to the human, wanting to be like Undyne. This activated an encounter that could not be escaped, giving Frisk the option to either spare or kill them.

If Frisk chose to spare Monster Kid, they noted that the human wasn't so bad after all and left. (This option aborts the Genocide Route, making it a Neutral Route.)

If Frisk chose to kill Monster Kid, Undyne got in the way. Monster Kid was shocked and left while Frisk fought Undyne the Undying.
