heres my thunderclash thus far using the following parts:

Combiner wars battle core optimus prime
Renderform thunderstruck kit
Beelzeboss hosting inside (minus the chest)
Reprolabels thunderclash set

 

Nice work, love how Donetello is photo bombing in the background

 

Haha he just wanted to stare at thunderclash's butt. Only thing I wish is that there were labels for the hosting inside legs
