My guess on new champion (with explanation)

New champ time, always a fun time for theorists, and here is my theory: The next champion will be a Bat like Void creature with a sound theme to their kit and a Battlecast skin on release. First: the noise in the teaser on the PBE, just being blunt, sounds like a bat. https://www.youtube.com/watch?v=O3rlRlKP0lI Second: All the void champions have a theme with some sort of sense: Cho, Kog, and Kha have hunger with it being less prominent in Kha; Vel has vision with him being an Oculothorax; and Rek has touch with her gimmick being feeling vibrations in the earth. So a bat as a void creature for sound could work in my opinion with echolocation. Third: Looking back at another void buddy, you can see Battlecast Vel in the back of Creator Viktor splash. http://pre08.deviantart.net/9097/th/pre/i/2014/034/d/d/creator_viktor_by_michalivan-d74ymsp.jpg Meanwhile in Vel's Battlecast art and Creator Viktor's recall, there is an image of an unknown flying Battlecast creature that could pass for a bat. http://i.neoseeker.com/n/0/velkoz_splash_1.jpg (to the right of Viktor) http://img2.mmo.mmo4arab.com/lol/creator_victor/victor05.jpg (lower right of recall on orange) http://apollo-na-uploads.s3.amazonaws.com/1420629155391/Viktor_Recall.png (still image) Fourth: looking back at all the post beta void champions their release skins were Mecha Kha'Zix, Battlecast Vel'Koz, and Eternum Rek'Sai, all three being robotic skins, this is what leads to the Battlecast being release skin, also with the Vel teasing scenario

If you have any other ideas with this theory, leave a post below, always love more ideas.
