I got tired of waiting for Hasbro to make the Decepticon monsterbots, so I decided to start making my own. I decided to go with probably the hardest of the three with squeezeplay the donors so far are a Titans returns weird wolf, G1 Squeeze Play and a powers of the prime blot. I have a good idea on how to attach the monster head. So it can fold up the back in robot mode. But I'm open to suggestions and questions

 

Let me be the first to say THIS IS AMAZING!!!!

 

Looks pretty interesting so far but I really got questions:
1. Why Fangry and not Crashbash for the head?
2. And why half of Wolfwire?
I was actually thinking of doing a kitbash with G1 Squeezeplay's parts, too. But I thought about using TR Deluxe class Repugnus. The beast mode head transformation fits but yours makes the beast arms be the legs for robot mode so that might answer my second question.
And I think you could use the beast head flap of Wolfwire for the weapon storage of a weapon for Squeezeplay in beast mode.

 

I absolutely love this

 

1 I only just finished with mock-up for I have to go to work and I couldn't find his head
2 I thought of using the second half of werewolf, but it did make him look way too tall and the chest piece has less to cover

And that's exactly what I plan on doing for his tail/ gun. I took the arm covers off of my donor squeezeplay has either back kibble if I can fit it or make his tail / gun since my donor didn't come with that. And I can post a photo of him with weird wolf torso extended if you like

 

No, I don't need to see this.
I'm really intrigued and looking forward to see this done. You are on a very good track  

 

Off to a great start, you great, big, cuddly bastard! Love where this is going, and eagerly anticipate updates.

 

For Horri-Bull, I recommend using Beast Hunters Voyager Darksteel as the base figure.

That's what I have planned for my own custom Horri-Bull.

 

I can't wait to see this finished! Nice work!
