Neutral Ending Octet by yopd_reality
After the second stage, Chara (1980) and Sans were exhausted, and Chara could only hit one of the seven Sans. Other sans will teleport away to find support (sans cannot teleport away actively, G teleports them). Sans will not die immediately after being hit, but he does not have enough physical strength to teleport, so he will stay and continue fighting for the purpose of delaying time.
The strength of all cnr!eto members weakened in P3, and the delay time was greatly reduced, but the speed of the other sans looking for support was greatly increased.
Cnr!Killer sans (OST-08) has carried out massacres and has high HP. Chara's strength has been weakened and he is exhausted, unable to deplete Cnr!Killer's HP in one attack.
