A couple of days ago, I came across this cool MOC by Geng Lei loosely translated as Flying Tigers. This MOC consists of a couple of the new LEGO Speed Champions sets as well as from the LEGO City Monster Truck Transporter (60027).
The MOC gives off a Voltron Vehicle Force look to it combined with a Transformers feel. The skeleton of the mech is created from some LEGO Hero Factory parts while the exoskeleton is created with the various vehicles including the McLaren P1, Porsche 918 Spyder, and two Porsche 911s.
As a fan of both Voltron/Transformers and the LEGO Speed Champions theme, this MOC to me is very well done and it gives off that coolness factor.
Update: Chris has informed me that the MOC looks more like Menasor which is pretty true.
