Programmer Kassadin
I don't really know how to post stuff, but I hope I didn't do anything wrong.
So I thought of Kassadin's quote: "You are null and void!" and figured he could be a electrician or programmer or something of the sort.
So he has an electric circuitry theme. Someone with more time could probably draw this better, but I didn't really have that much time since I was busy with other artwork.
His blade is now the familiar mouse cursor. Instead of the pipe things running from his mask, they're now electric wires. His skirt thing has keyboards hanging on it, plus he also has copper wire wrapped around his biceps. He could also have speaker shoulder armour, which could go well with his dance.
His skill particles would be changed, too. His e is the mouse drag thing. Although it'd make the shape kind of weird since it's actually a semicircle, I don't think it would be too much since only the player really needs to know what the area of his e is, and that would be reflected on the targeting reticle. I'm not sure what his q could be. HIs w would probably just make the cursor flash or something, and his ult could be like a drag and drop effect.
The colouration is not final though, because I kind of rushed it.
He'd also have some new quotes (probably more than just this, but I kind really think of many others).
Null Sphere (q): "You are null!" "Return 0!" "Break!"
I can't think of anything for his e or w.
Ulting: "Cut and paste!" "Goto!"
Attacking: "Resolving bugs." "Debugging errors." "Fixing glitches"
Joke: "The great thing about booleans is that if you're wrong, you're only wrong by a bit." "ASCII a stupid question, get a stupid ANSI."
Taunt: "You are merely a bug in the system." "You're syntax is incorrect."
That's it. I can't really think of much else because I'm kind of tired right now. Let me know what you think!
