2018 The Climb video Champ Teaser/Zaun Chem baron

So in the new video released by riot we see ekko fighting zaunite thugs but we see one with a caustic weapon who ends up defeating ekko and poses the thought of a champ teaser. could be nothing or could be a zaunite chem baron champ who riot could be workin on. considering the time frame of a new champ its possible and if its nothing could it be something. the devs of league have made champs from ideas created by their fan base so please reply below.
