Mobile Suit Gundam: Iron Blooded Orphans is worth watching not only for the amazing mechanical designs, but also for the fact that do a lot of things with the story an characters that turn Gundam tropes upside down. The Vidar is actually the (better looking, in my opinion) version of the Gundam Kimaris, a villain mobile suit gets a lot of neat battlefield moments in the series. This one is made from RAFM Heavy Gear parts, a Mekton, a Battletech Commando, a Marauder, and various other bits and bobs.
The actual Vidar has wing shields on extendable arms on its thruster backpack, but I just plain didn't have the bits, and so opted for sensor aerials. They look like vestigial wings, which is rather the point.
Those big things on the hips are binder that hold replacement foils for the Vidar's close combat weapons; oversize armor-pierceing fencing foils. It's also meant to have a set of hidden handguns in the front armor panels, but there's only so much you can do at this scale.
Those shoulders are from the Insane Kangaroo Hunchback model, which comes with parts for every variant and thus a wealth of conversion fodder. It has the wheelie heels for ground mobility, because it's meant to be a space unit adapted for ground combat. It still has the huge thrusters in its calves, knees and backpack, so it's more than capable of getting airborne in the lower gravity of Mars.
Happy Cyber Monday, people.
