Various Skin Ideas
With nothing better to do on a 6-hour plane flight, I thought up a few skin ideas (in varying levels of completeness)...
Desert Rose Zyra
Initially inspired by some particularly nasty brambles I ran into hiking in the Grand Canyon. I haven't found an identification for the particular plant yet, but some sandy runners covered in spines would fit her E well. On death, she turns into a thicket of desert brush and blooms. Zyra herself would be clothed in Arabian/Saharan-style desert garb.
** Tropical Storm Amumu**
(Of course he doesn't make hurricane status) A windswept Amumu in a poncho. Q throws forth a storm surge, and the following swell carries him to the target if it connects. W brings heavy rain and flooding around him, and E a flash of lightning. R brings the full hurricane in, with the characteristic clouds, rain, and wind swirling around him in a wide radius.
** Meteoric Brand**
Brand cast out of a cratered nickel-iron meteorite. Q throws a meteor forward, E causes a sudden fiery impact on the target which spews more projectiles if ablaze. W begins with a shadow on the ground which rapidly grows as a meteor plunges down from above and blasts out a short-lived impact crater. R hurls a comet at his target.
Snowsinger Karthus
Dressed in white furs/sealskins. Q causes cracks to spread from the target center as the ground there turns to ice, ending in a jagged hole cracking open as it deals damage. W calls up a phantasmal glacial wall, which calves as champions pass through it. E brings swirling snow and howling wind around Karthus. R appears as the aurora above enemy champions (perhaps with whale song as the sound effect?).
** Titan Braum**
Fitting into the Greek Mythology theme of Mythic Cassiopeia and Perseus Pantheon, Braum would do well as an Atlas type - in ancient Greek dress, holding up the sky and so on.
** Space Raider Gangplank**
Wearing an armored spacesuit and equipped with a laser pistol and a force blade, GP can toss around some high-tech bombs, whip out a first-aid kit, and call down hypervelocity kinetic strikes with his ultimate. (If anyone's read In Fury Born, that's the inspiration)
Rebel Pilot Corki
I'm not really sure this is possible due to copyright sorts of issues - but Corki flying an X-wing would be awesome. Q drops bombs, basic attack is a blaster cannon, R the torpedoes, and W hyperdrive.
Bengal Nidalee
An Indian-themed Nidalee skin, turning into a tiger. Because tigers.
Shyvana the Golden
A Hobbit-themed Shyvana: in human form, decked out in golden and jeweled dwarven-crafted arms and armor. In dragon form, covered in gold in the style of Smaug.
Archangel Aatrox
A concept of Aatrox as an angel before Falling. Robed in white, winged, and haloed (but still with the same helmet and body shape for recognizabillity) , carrying a shining straight sword. Basically, light wherever classic Aatrox is darkness and blood - sword flashing on the 3rd hit, wings spreading in a flash upon flight, and the ult drawing in light from around him.
Fisherman Blitzcrank
Credit to tugwos for the idea: Blitz casts out his line and reels in enemies. W revs the engine of his motorboat, and for his E he hauls up a big fish and smacks his opponent into the air with it. R could be either a cannonball jump or an attempt at dynamite fishing.
Would love to hear any thoughts!
