[Champ idea] Cyl Peacekeeper of piltover (open to any suggestions)

This Champ, in concept would be a tanky, ap bruiser specializing in heavy CC and locking down the enemy team. Cyl would not use mana but would instead use a resource like energy but not because he's a robot. instead it would be called charge which he starts off with 200 and a regen rate of 20 per second. (side note: i am still toying with many things including his name, the cd, cost of abilities, and range of abilities so basically everything is still wip)

His passive would be adaptive exoskeleton: the last enemy that damaged him (including monsters and minions) will do 5/6/7 % less damage to him. This would make him ideal for dueling in the top lane or for tanking damage in the bot lane.

His q would be Concussion blast and would work like Vayne's condemn but be a skill shot, about the size of blitzcranks pull. it would do some damage 50/70/90/160/250 and would scale off his max health, if they come into contact with a wall they would take double damage and be stunned for up to 2 seconds at max rank, this would be his main damage dealing ability.

His w would be Surge and be a toggle that would create a small aoe around Cyl that would slow enemies by 30/35/40/45/50 % and deal 50/60/90/120/180 +70 % of his ap magic damage per second

His e would be an auto attack empowerment (name still undecided) where he loses 35/30/20/15/12% movement speed but his next three auto attacks would deal 20/30/50/70/90 + 70% of his ap bonus damage, slow by 50/55/60/65/70% for up to 2 seconds at max rank

His ult would be a multi cast (name wip) where when activated he gains 30% movement speed and two shots for 10 seconds, can be reactivated twice to fire a shot each time. The first shot would slow by 30/40/50 % for 1/2/3 seconds and deals 200/300/400 damage +90% of his ap, the second shot will do the same, but if it hits the same target it will do 400/600/800 damage with a 120% ap ratio

Lore is still in progress but i think he would be a guard bot made by heimerdinger to help protect piltover.

I would imagine he looks big and about the height of Sion with two wide arms that resemble shields and during his ult convert into cannon like arms, his left arm will end in a gun barrel protrusion (sorry i have no picture) he would have yellow glowing eyes and have semi-hostile peacekeeping programming. He would also be a gleaming chrome color

Possible interactions:

when against a battlecast skin:

"programming flawed dispatch sequence initiated" After killing one: "404 not found"

Taunts: action slams sheild-like arms into the ground and electricity arcs across his body "i am run by 4 billion lines of code it will only take a few of those to kill you" "those who disturb the peace deserve whats coming"

Jokes: action thunks chest and gets shocked

"cant put a dent in this-oww" "Im indestructi-agh! shocking"
