Iv Been thinking RIOT,It would be pretty cool if you guys made a alien vs predator skin with 
and 
.I know there is most likely alot that goes with that besides make a genuine skin for both that would be as close to alien and predator as possible.Its just an idea that i thought would be pretty cool.
Xeroyeti3 votesi would think, alien vs predator is inspiration for these characters originated
FriendIy Psycho3 votesHead hunter rengar is meant to be predator and normal skin kha is meant to be alien it wasnt based off of it just ended up that way.
Kjnava2 votesYes, Head Hunter is definitely a major resemblance to Predator. on the other hand doesn't look to much an Alien though. I do believe they can create an Alien skin for him by simply making his head longer for upgrading Void Assault, Giving him a tail that he AA's with and uses the tail for his Q. Void Spikes don't need to change too much since the aliens seem to have the same detail. As for leap whether they keep the wings or not it's whatever, but i believe they should get rid of them and implement the Alien's legs on to him. When he gains all 4 Evolution stacks he should undergo another transformation to make him look like the Alien Queen from AvP or the Hybrid from AvP2.
Waka Floka Swain1 votesI agree with you as far as both champs go. With small details are what makes the skins (pop) say for instance, the shoulder weapon on predetor can be used to shoot bola strike. Alot of his other attacks kinda give you the look and feel of predetor. Riot could put predetors mask on him and give him all the sounds and noises. With kha zix i could see them putting acid in the place of void spikes.
Waka Floka Swain1 votesIm Actually gonna draw up a rough draft for both. I have some fairly decent art skills it will take a day or two because of time restrictions but it will be worth the time spent.
