The Return of the Duck [Champion Concept]
A duck champion cannot just be a plane duck, it has to have something special about the little guy, so...
Meet X72, a genetically modified experiment deep within Zaun that turned what was once an ordinary bird into something that resembles a duck in our world. X72 may be his actual name, but the code name that he goes by is Project Xavier or just Xavier for short.
The purpose of making Xavier was to create a biological weapon that no one would notice was a weapon at all at first glance. This would allow him to sneak into places to cause complete havoc and destruction from within. Unfortunately things did not go quite as planned as Xavier ended up gaining super genius capabilities to go along with his power, and of course no one likes being cooped up somewhere by force. So what ended up happening was that Xavier blew up the lab that created him and escaped, flying up high to Piltover where he now resides among the roof tops and streets.
An independent bird that is both a super genius and a weapon of mass destruction is a very dangerous thing that is now roaming the world of Runeterra. He takes whatever he wants, either through cunning tactics, or straight sneak in and brute force take what he wants. Xavier is never seen doing anything bad which makes it even harder to know if he is around to take what he pleases, since no one alive knows who is behind when an entire base blows up or valuables parts get stolen. Why would anyone clue in a super genius bird is the reason these events keep occurring?
Why does Xavier keep stealing valuable parts from highly secured locations? We do not know the answer for sure, but it cannot be good once whatever the parts are being used for is finally created...
What position is the true master mind of the game that no one expects to deal a bunch of damage as well? That is right, it is support, Xavier is a support-assassin and the assassin aspect is his ability to create kills seemingly out of no where through very strategic gameplay. Even though his character may be about doing things solo, in game he sets up his team to do the killing for him, that way no suspects that it was him for the reason your screen lacks colour!
For the record, his second skin got to be Ducktwo, something that resembles the looks of Mewtwo, minus the fact that Xavier is not a clone.
