(( -Unlike his normal counterpart, who gouged out his eye just cuz, Underfell!Serif gouged his out for a reason. It was to symbolize him breaking away from the Dreemurr Regime, since the eye was embedded in him under orders from Asgore. -He didn't steal the eyepatch from Undyne. He just asked for one. Since my headcanon of her is a huge pushover, she agreed. -The crack in his skull is from gouging his eye out. Seriously, that thing is powerful. -He thinks his Undertale counterpart is insane. -He and Asgore were close friends, even though Asgore executed his fiancee. Sans was deceived into thinking it was a lab accident though, and only found out the truth after Papyrus died. -The rebel group that Underfell Serif leads is called 'Snow Angel'. [SUCCESSFUL REBELLION VERSE] -When he finally gained enough LOVE to kill Asgore, he took over the throne and began reforms. Because of his kindness and the fact that he was a skeleton, the residents of the Underground started affectionately calling him 'King Calcium'. When he found about this, he happily accepted the nickname, even changing his SMS username to 'Lord_of_malkkkkkkk_420'. ))
