Mecha Vel'koz is in PROJECT: Katarina's Splash Art

Hi guys !

I was watching the new Splash Arts for the incoming PROJECT skins, and I'm literally IN LOVE with them. But while watching Katarina's splash, I saw something. I saw Battlecast Vel'koz !

Look, here's the Final Splash Art for PROJECT: Katarina

For me it is clearly Battlecast Vel'koz. Red eyes, mechanic tentacles... Yes, it's him. But why is he in there ? I don't know. Let me guys know what do you think about it. And please, tell me that I'm not crazy !

Here is the first Splash Art for PROJECT: Katarina that we saw and that was linked. Battlecast Vel'koz wasn't here yet.

Edit : It's Battlecast Vel'koz, not Mecha. I made a mistake in the title, sorry !
