Maybe then Asriel would absorb the black soul and become something else.....

The hearts on his body will be shattered and along with the original meteor attacks,will shoot lasers.The battle continues until the hearts fuse and the black soul appears,which then you appear as a battle sprite and are able to control your own variety of attacks to attack the CPU,including a blood-dripping bandage,sticks that home in the soul much like Undyne,the swinging Heart Locket,and knife attacks,functioning as Asgore's attacks,etc.Once the CPU is at 1 HP,next to your battle sprite will appear a MERCY button which you will press in the True Pacifist route only.Then you can go to the save point and it wil state,"You did the forbidden.You used...magic.Your powers...they fill you with not determination...but something else..." relating to the love that monster souls are made of.Whatever.
