The Energon Pub

I found these two parts in a box and can't for the life of me figure out which toys they go with. I've tried the TransformerLand part database with no luck. Does anyone have any idea what they are?

Thanks!

Not 100% sure, but I believe the grey piece with the purple circle is from Armada Unicron, while the other piece can be from either Energon Inferno or Robots In Disguise (Car Robots)Hightower. Once again, not 100% sure.

The gray and purple piece was from Unicron (thanks!), it was a hip guard. The red one is still a mystery though, it doesn't appear to go with either E-Inferno or RiD Hightower.
