Champion Concept - Xero, Piltover's Assassin

Okay, Xero is not supposed to be taken as a steal from Borderlands 2's Zero character. While I love that game, I didn't have any kind of influence from him in this concept. While you are reading through this post, keep that in mind and give me any feedback on what's unbalanced about him. I am not a professional game designer, so I don't know how to balance champions for gameplay. Anyway, enjoy!

Xero, Piltover’s Assassin Position: Top, Jungle, Bottom // Role: ADC, Assassin

Health: 347 (+31 per Level) Mana: 422 (+43 per Level) Attack Dmg.: 49 (+12 6 per Level) Ability Pwr.: 6 (+ 3 2 per Level) Armor: 9 (+7 3 per Level) Magic Resist: 11 (+9 4 per Level) Attack Speed: 0.85 (+3% per Level) Movement Speed: 288 (+11 5 per Level)

Lore: After scientists in Piltover learned of Zaun’s creation of Blitzcrank, they felt that they needed to create an animatronic of their own. Thus, the near-living weapon designated as X-3R0 was made. For months, X-3R0 roamed the streets of Piltover aiding Caitlyn and Vi as best as it could, and eventually the police sent it to attempt to track down Jinx, but to its best effort, X-3R0 could not find her. In a last-ditch effort to keep their creation around, the scientists begged Piltover’s military to give X-3R0 one last chance. So they gave it an impossible task: Kill the Noxian assassin Katarina.

On its way there, X-3R0 abandoned its handlers and when they came hunting for him, he gunned them down. The creation meant for so much good had turned. He found an isolated village and stayed there for a time, but was eventually discovered by a young man. This young man pitied the automaton, and tried to help.
After seeing its designation, the man gave him a name and gave it help to gain control over its fear and anger. Soon after, Xero left for the League of Legends to claim the prize it set out for so long ago...

EDIT: Changed some values around in the base stats and their scaling. Thanks to Regret Exegersi, I found out that the values were quite ridiculous, so thank you for that!
