Alphys and Undyne in Undertale

Alphys and Undyne are two female characters in Undertale that form a romantic relationship if encouraged by the player. Alphys is a reptilian monster that serves as the Royal Scientist to the Kingdom of the Underground. Undyne is a fish-like monster who serves as head of the Royal Guard. The two can be seen together in the epilogue to the game’s “good” ending, in which Undyne kisses Alphys on the cheek, causing her to faint.
