EKKO SKIN CONCEPT (If you have an imagination it could be amazing!)
TL;DR : MARTY MCFLY EKKO SKIN WITH FIRE TRAIL ON THE FLOOR AFTER HE ULTS
Well, even though i am not an Ekko player (come to think of it, I'm not even sure if i own him) I have had this idea since his release and I'd be very surprised if other people hadn't thought of something similar! My idea is for Ekko to have a skin modelled after Marty McFly from back to the future. He would wear a denim shirt and jeans with a red body warmer on, with shabby hair and white sneakers (google a picture of him, if you haven't seen the film and if you haven't seen the film i highly recommend watching it also!)
His Q: he could throw out a an electric guitar that spins as it travels His W: he just dashes as usual His E: he throws a clock up into the air at a target location and when it lands it creates a red circle on the ground His R (my favourite bit): Ekko Jumps on his skateboard and dashes back to where he was 4 seconds ago leaving, wait for it, FIRE TRAILS ON THE GROUND!
HIS RECALL CAN BE THE SAME AS IT IS BUT HE PLAYS 'AINT NOTHING BUT A HOUND DOG' (or something similar if copy write is an issue)
Ekko's cheekiness is something which makes him SOOO similar to Marty McFly and i really think Riot would be missing a trick with the whole time traveling thing if they passed up this opportunity! 
Thanks for everything Riot, I know you get a lot of stick for A LOT of stuff but I know you care about the community :)
See you on the rift, BUTTHEAD! :)
