Oh boy, two concepts about destructive deities in a row!
Anyway, in SMITE, Perses is a greek assassin that benefits from just killing things, but is not as good early game. He is depicted as such:

(Not my artwork, so don't sue me)

Difficulty: Average
Attack progression: 1x/.75x/.75x, the last two attacks dealing damage in an AOE around him

Passive - Destructive Tendencies

Whenever Perses or an ally kills an enemy god, he gets a stack of anger. each anger stack provides physical power. If he or an ally destroys a tower, he gets 3 stacks instead. He can have a max of 10 stacks, and at 5 stacks or above he gains extra true damage on his abilities and auto attacks. He loses 4 stacks on death.

Physical power: 5 +.5 per level
Extra true damage: 10 +5 per level (10% of physical power)

Ability 1 - Mighty Cleaver

Perses empowers his axe, granting his next successful auto attack extra damage. If he used an ability before using this one, the empowered attack ignores a percentage of the target's protections.

Mana cost: 40/45/50/55/60
Extra damage: 40/70/100/130/160 (25% of physical power)
Protections ignored: 10/20/30/40/50%
Cooldown: 12 seconds

Ability 2 - Smash of Destruction

Perses slams down his axe, dealing damage in a small cone in front of him and rooting gods into the ground.

Mana cost: 70
Damage: 70/120/170/210/260 (70% of physical power)
Root duration: 1.5 seconds
Cooldown: 14 seconds

Ability 3 - Spinning Death

Perses dashes forward, spinning himself and his axe around as he goes, dealing damage to nearby enemies. If he uses Smash of Destruction while dashing, it is canceled early and he uses his 2, granting it extra range.

Mana cost: 60/65/70/75/80
Damage: 40/70/100/130/160 (70% of physical power)
Cooldown: 17 seconds

Ultimate - Glorious Entrance

Perses summons a pillar of rock in front of him, and he jumps on top of it, becoming immune to CC and damage for a duration. He can then reactivate the ability to jump down from the pillar, dealing damage to enemies he lands on.

Mana cost: 80
Immunity duration: 6 seconds
Damage: 140/240/340/440/540 (80% of physical power)
Cooldown: 100 seconds
