The Official Sans Design is here! (sketch made by: Barfy, the creator of dustcord himself!) heres some facts about sans in pacifist.
-Bio for Sans (Unknown Remorse, Pacifist Dustcord)-
he is both more insane, damaged, and the sash on his lower body has been fallened off from many battles
he is LV 18 (because he is insane after all.)
Sans would not just use determination in the final fight with the human...he tries his best to kill you without anything to give him a "boost"
Sans in Post-Pacifist Dustcord would basically head to undynes lab, and undyne would inject determination into him...making sans "stronger". but in Pacifist, he doesnt care if Undyne tries to help him, and Papyrus warned Sans about what Undyne would have done, right before the moment Sans kill her...
Sans would have 1 area encounter + 5 phases in the Final Area (aka the Final Corridor). Sans would have to battle the human in "Raindin" for the humans first area encounter...and instend of Sans running away from the human in Post-Pacifist, Sans is brave enough to battle the human...but after sans realised that he needed more LV to actually kill the human, he runs away, by killing the human first.
Thats all for that, now its time for the PHASE LORE! (Quick Note: All phases can be 1 hitted expect phases 4 and 5 and alphys during phase 3, because sans and papyrus arent expecting you to actually fight [so you can literally finish the game by 1 hitting phase 1, but you get a bad end])
Phase 1 Sans whispers to paps' skull throughout phase 1 as his sanity breaks away slowly
He isnt really focused on the human and is only putting out attacks to amuse them Difficulty: 2/5
Phase 1.5 Sans becomes angered that you wont kill him and snaps his staff in half (Fun Fact: Phase 1.5 can be skipped by attacking and breaking the papyrus staff causing sans to get pissed off and it cuts to phase 2.)
He is now becoming more aware that he is in battle Difficulty: 1/5
Phase 2 Papyrus's head has detached itself from the bony staff and begins floating around, slowly turning into an object that resembles papyrus
Sans has been pissed off by the human trying to interfere with his time with paps Difficulty: 4/5
Phase 2.5 Sans uses the PATIENCE soul to reincarnate papyrus' skull into papyrus and the INTEGRITY soul to resurrect alphys Difficulty: 0/5 (transition phase)
Phase 3 He now has his friends by his side and realizes this was a mistake He and papyrus kill alphys and sans and paps fight throughout the whole phase
You've been caught in Deadly crossfire Difficulty: 5/5
Phase 3.5 Sans leaves to let you and papyrus have alone time Papyrus tries to get you to turn around and reset
Sans comes in at the end and kills papyrus again Gaining g more LV Difficulty: 3/5
Phase 4 Sans has gone completely insane No memory of papyrus stands
He is only focused on killing you Difficulty: 5/5
Phase 4.5 He has run to his whit's end To relieve stress he starts slowly sawing his limbs off
Any hope of reasoning is out the window (Fun Fact (Again): There is no way to avoid sans' mutilation in phase 4.5 unless you killed him in an earlier phase) Difficulty: 0/5 (transition phase)
Phase 5 He has become nearly a GOD But the souls have messed up his senses
Dont move, his vision is the worst He cannot directly attack you unless you move (Another Fun Fact: Sans can only attack you while you're moving... Thus the name: "Static Vision")
Difficulty: 2/5
Phase 5.5 The souls have denied sans He has turned into a helpless flower
He pleads for you to end his suffering Difficulty: 0/5 (choice phase)
(Please note that I HAVENT made these ideas for the phase lore...Barfy made both the design, half of the ideas for the bio of sans, and the ENTIRE Phase Lore...) anyways, I will post the theme names for the encounter and phases next.
