NEW Champ Ide

I was writing the other day and ended painting an fox, I painted with a school penn so it became very dark. And then it hit me.... GRIM THE SHADOW FOX. I have only tought about it a couple of days and have came up with some attacks and a passive, the ulty and the Q. And I tought maybe the Q he would like jump up a little bit in the air and do a barrel roll and do a areal damage around him, and I tought maybe he would have like blades out of his front paws maybe little bit like Nocturne. I havent came up with the other spells yet and im not sure about the name but I hope that this will get a big discussion and that I get a lot of tips and ideas. The look I tought about is in the link but not exactly like that but you understand.

Concept: Grim is a melee Assasin with mana, lurking in the shadow of the jungle. He is an AD champ with much attack speed, will maybe be able to play as an mid-laner after I maybe will do his W that will probably be a passive that will do AP damage. (Not finish with that yet) The main thing is that he is very fast both attack damage and movement.

Appearance: He will be a dark/grey Fox with a quite long tale with a white tipp on the end of it. His eyes will be spokish white or maybe blue. His chin will be white with little bit of whiskers. You will not be able to see his mouth and there will be like some smoke Coming out from him. He will have do blades Coming out of his front paws in scimitar Looking way.

Passive: Grim will start in a small ''Gnar'' size and increase extra 10 attack damage and 2.0% attack speed every ulty lvl (6, 11 and 16) from lvl 6 be in like Nidalee beast form size. At lvl 11 he will be a little bit bigger, and end up in a little bit of a Nasus size in lvl 16, maybe little bit bigger but he will stand on all 4 legs.

Stats: Health: 575 (+73 per level) Attack Damage: 58 (+3 per level) Ability Power: 5 Attack Speed: 0.7 (+2.5% per level) Movement Speed: 360 Armor: 27 Magic Recist: 32

This is everything I have came up with for now.
