The Satsujinki attacked Horror Sans. Ofcourse Horror Sans attacked back, causing a upbringing of chaos and destruction upon the two. Meanwhile, the Human saw this as an opportunity to flee and kill some monsters. After a rough and intense battle, Horror won. Though he gained a few injuries whilst existing ones worsened. He gained alot of LOVE and DETERMINATION, he felt immense power rushing through his bones. Though after awhile of this great feeling, agony struck. He started growing significantly to the point of 6 foot and 2 inches.

Description: Terror's Stats - LV: 66 ATK: ??? (randomizes per hit, maximum DMG: 999 DMG - minimum: 1 DMG) - Physical ATK: 50 DEF: 666 (DMG Reduction: 66.6%) HP: 1408 Terror's Abilities - Maniac's Blasters: Due to hating Gaster for getting him into this frenzy, he doesn't want anything involved with him, including his blasters. So he got Mania to make some. They're thrice the size of Gaster Blasters and twice if not thrice the power of Gaster Blasters. They can even go as big as the Sun, and destroy a planet or two. Perseverance Bones/Purple Bones: These bones are bones that home in on the target and deal the randomized damage, though only 1 Damage up to 99 Damage. (you will soon see what I mean by randomized Damage when you see the stats) Determination Bones/Red Bones: These bones are bones that don't home, but deals tons of damage, that damage ranging from 100-999, but thats when it explodes on the target (it has a set time before it explodes), but when it hits the target, they get sent down to 1 HP, but if they already are on 1 HP then they die. Red Soul: essentially Blue Soul but when thrown around it does 2-5 DMG (2 DMG if the target has 99HP or below and 5 DMG when the target has 100HP+) Bone Axe: he can summon a bone axe, the Bone Axe has 3 modes Axe Modes - Standard: acts like a normal axe, no projectile slashes or anything Perseverance: shoots out homing projectiles when slashing TRUE MODE: acts like the true knife, dealing 99999999DMG but he can only uses 3 swings each swing makes him drain energy by 33.3%. (this is the only time he can get tired due to his never ending stamina because he is part Insanity) after using 3 hits, that's when he is vulnerable. Vulnerable Mode is where his HP comes into play.
