I did doodle organic Monty as a motorbike gang member and liked his design and look so much that I wanted him to always look like that. So yea, re-design time.
So that means he no longer has metal armor part/metal skin but his head and neck area, but its all rubber/latex whatever now which makes his design more consistent I guess. I also gave him a nice leather jacket and made his hair more spiky and messy looking to give him a even more wild and aggressive look.

I like that he can now roll his "sleeves" back, like they do in old warnerbrothers cartoons when they are about to start a fight. I think that's funny.
And in the first sketch he took of his chest piece to get better air flow because it's too hot.
And then I just did a meme that I thought fit Monty and Freddy's character. Monty tries to convince Freddy to be more aggressive and mean like him. But I think Freddy probably just refuses.

update: I added two more sketches to the pile
