Overwatch x harry potter crossover fanfic brainstorm

Disclaimer: I do not own any of the writes to any charters or stories, all of this is just for amusement

So I had this idea after seeing a comic about talon not having a healer. So for some reason I thought of harry as a good fit but with more of a back alley doctor vibe. So after some thinking I decided to make this to try to come up with a story for him and try to encourage people to try this concept out. Also I'm mostly coming up with this as I go so it might not all match up.

Codename: Smog

Name: Harry Potter

Role: Support

Basic attack:

Toxin: a semi-auto rifle that is used best at medium range, can look down sights for better accuracy

Abilities:

2nd hand smoke: smog lets out cloud of smoke that slows enemies in it.

Numb the pain: smog throws down a healing smoke grenade that takes a second to activate, it also blocks line of sight for enemy players.

Ashes to ashes: Smog can revive one alley at half health but that alley cannot be revived a second time. Takes a long time to charge up and costs half of smog's health to so this

Ultimate:

Last Breath: Smog covers a large area with smoke that heals allies and slows enemies

Passive:

Any smoke effects smog lays down interrupts the enemy's line of sight attacks and while allies are in the smoke the enemies can't see them tough walls.

As you can see I designed him to be more interruptive than healing and I'm unsure about the resurrection ability being over powered but hopefully I balanced it out, didn't want it to be an ultimate because it is supposed to be something minor in the way of combat.

Harry's back story is more ordinary than other fanfics, if you want to change it go ahead,

harry fell into the vale and ended up in the overwatch universe with no magic, and is, shortly after arriving, captured by a company trying to replicate mercy's prototype healing, but they need test subjects and what better test subjects then people who doesn't exist to any government on their earth. So after harry becomes a test subject and finds others that were sent into the vale also as test subjects, he tries to look for Sirius, and eventually does but he is dead, after finding out how he died harry goes on a rampage, breaking several of his morals in the process. When doing this he damages the communications causing talon to now know where the testing facility is and naturally sends a scouting party to check it out. As harry continues on his rampage though the facility he finds the head scientist hiding in a lab and when he goes to kill him the scientist stabs him with the closest thing he can: an experimental formula of mercy's healing nanobots. This caused harry to pass out from his wounds after killing the scientist. After he wakes up he starts coughing up smoke and continues his rampage filled escape and ends up killing most of the facility. As he is killing the last of the guards talon arrives and tranquilizes him. And talon after seeing what he did and how his new powers work offers him a job to work for them and seeing as the other option is still being a loophole in all laws he chose it become smog: healer of talon

After writing that I have half a mind to write this myself. I might, might not but meh.

Tell me what you think and tell me if this inspired you to make a talon medic harry fanfic.
