Lore: After the 7th human defeated ASGORE, they left the underground. Chaos erupted in the underground, and Toriel took back the throne. She declared humans who fell down would be treated with care, but the monsters didn't accept this after the recent human defeated ASGORE. The monsters overtook the throne, and the captain of the royal guard, Undyne, took over. She declared humans who fell down here...must be (put to sleep). The underground fell into Hunger. Undyne took Sans eye, and powered the core. a new human fell down, by the name of Aliza. She showed the monsters no mercy, filled with fear. at the end of the Judgement Hall, Sans faced off against this human, with an LV of 15, but failed, and was defeated. After this happened 7 more times, he remembered the routes Frisk and Aliza have done. With this knowledge, he decided to get his eye back from the core, defeating monsters who stood in his way. He grabbed the eye and stuffed it back in. He then watched Aliza very very closely...but he did have a few lunch breaks. He managed to actually make a burger and a hotdog. He also found his Abandoned Quiche. He was ready to avenge his fallen brother...save his world, and maybe even forgive Undyne if he won. but most importantly...he would make the human... ...FEEL THE CONSEQUENCES OF THEIR SINS.
(you can think of this as Horrortale: Hardmode) This Sans of mine has extreme strength, and speed. He also has 4 axes for melee plus one he can summon out of bones, and 3 throwing axes. His accuracy is 80%. The axes for melee are two big ones and two medium ones. the one he can summon is big. the throwing axes are small. He also has his blaster's back cause of him getting his eye back, and yes, he still has semi-immortality, unless his eye is destroyed, but those who try to grab eye have failed, and they leave a burn on their hand. only someone with a HUGE AMOUNT of determination or a specific power have the courage to take out the eye and destroy it. If his stamina in below 25%, he can activate RAGE, making it to where his defence and attack increase by 5. the more damage you do to him, he gets stronger and gets more defence. it also increases his stamina, BUT. he can only use RAGE once in a fight, it also heals him fully. Also, deleting him won't work anymore. it will take three slashes to defeat him. But destroying his eye will either defeat him instantly (90%) or it will keep him alive, BUT you gotta either take his other eye, or do two slashes. Beware though, the other eye still burns. You have permission to use this, just credit me.
