Alex is normally a kind person as said by Kyle. However, on the genocide run, they stop you by fighting. Unlike Chara, they don't kill you in one shot, and provides a fair fight.

Story
Alex was the first human to fall underground. Alex was on the verge of death, but Kyle saw them and took them to the house. They're wounds were treated by Rial and were given cake by Maven. Alex was considered part of the family.

Alex wanted all monsters to be free, so they sacrificed themselves to Kyle. However, they're plan went awry due to Kyle's kindness. This caused Alex's death and Kyle to become Sunny. The whole kingdom was depressed and caused Maven to start the war.
