Afraid of Water. When in water or underwater, the Almighty One becomes frightened and can only use its action to run away until it's out of the water. 

Fuzzy. Wherever the Almighty One moves, it leaves a massive trail of hairs behind, turning the ground where it lands into difficult terrain.

Electrocution. The first time any creature performs a melee attack on the Almighty One in combat, it must roll a DC 26 Consitution saving throw. On a failure, the target takes 6d12+8 lightning damage. The target takes half as much damage on a success.

This is still just a cat. The Almighty One is immune to fall damage.

Multiattack. The Almighty One makes three attacks: one Chomp and two Scratch

Chomp. Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 48 (6d12 + 8) piercing damage. 

Scratch. Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 50 (7d12 + 4) slashing damage. 

Feline Dodge (2/Day). The Almighty One entirely dodges an enemy attack, taking no damage from it at all.
