Old Boss design for a VR project

Hey guys，here is an boss concept art which I did for a boss fight in a VR project 3 years ago, I suddenly found it in one of my previous drivers. And even now, I still find it interesting to share, so thats it. 
I designed this guy with many comments, like he can use both melee weapon and ranged weapon, he needs to be an attacker and a defender，he must have some kind of ultimate ability......and blablablabla....so thats it.....you can get all the comments here through the concept, But it was still an funny experience doing this..... 
And again，unfortunately，this project was still cancelled at last，so that means you can not play it with your VR devices any more. You guys might be wondering why most of the projects that I have been working on being canceled eventually.....
Almost forgot，he can also explode him self randomly....
