When i was 10 years old my family died on the surface. i were living alone,eating garbage,sleeping on the dirt,etc.. i joined the war but already lost. so the humans sealed us in the underground. when i were roaming around i found sans and papyrus. they took me to their house. they were treating me like my family.after 2 months they both started training me, so i can protect myself. 5 years of training passed and i became reaally strong. i wanted to roam around in the underground, i found the temmie village. the village were getting attacked by a weird looking monster. as i stepped in the village i ran into him and striked him. the monster were injured so badly. so he then ran away, i returned to the village after 3 months and all the temmies came running to me. they gave me a house,armory,better clothing,etc and started calling me "tem boss"
