in the episode with the space barnacles the monster ended up being a green decepticon
anyone know who it could be?
cause I'm confused I thought it would be a constructicon but it's not

 

the monster didnt end up being anyone, it was a mash up of the 2 construction vehicles and megatrons damaged body

 

Oh ok that makes sense!
Thanx

but doesn't Sumdac find it at the end?
so it could show up later.

 

I think Sumdac finding it was played out with Megatron finally getting enough of his body back to be rebuilt.

The space barnacles themselves could come back (though why, really?), but most of the body went back into Megatron as I understand it.

It has, it's Megatron's body now. It was rebuilt by the Allspark key.

 

are you just now watching the show? It's been resolved and revealed for quite a while now.
