Toriel ideas:

3x HP (1320)

Actually 80 DEF for the first 55 turns, while in pacifist it only takes 50 turns to spare her (add 2 turns for each kill, so 128 if 1 kill short of genocide, max encounters 40 instead of 20)

Plenty of blue and orange fireballs (perhaps some green if you have fewer than 5 kills).

8 damage per hit on pacifist/neutral, 16 on genocide (thus full 80 ATK). If your HP is at 3-5, 2 damage per hit.

If you try to betray-kill Toriel, you do up to 120 damage, and Toriel can no longer be spared unless you do less than 30 damage (an intentional weak hit). First hit in genocide does the same damage, and you can't abort genocide at Toriel.
