RGM-79 GM - While there are over a dozen different GM variants to choose from, the one in game is simply known as GM.Both look pretty decent, and the MG kit comes with a tiny cow. WD-M01 ∀ Gundam - You've got both an HG and an MG kit to choose form for Turn A.MSA-005 Methuss - Only a single, old HG kit exists for Methuss.There's also an MG kit available that also looks great. ASW-G-08 Gundam Barbatos - The HG kit of Barbatos is pretty damn good for how inexpensive it is.Prepare to pay out the nose, assuming you can find them. RX-80PR Pale Rider - The only Pale Rider kits I could find are all P-Bandai HG kits (Bandai's online limited exclusive store).There's a really old HG kit available and a more modern MG kit, along with a prototype version in HG Origins flavor. RX-75 Guntank - Not a lot of choices here.So far as I can find, only a single HG kit was ever made of him. ZGMF-XX09T DOM Trooper - Don't confuse him for the regular Dom, Rick Dom, or Dom Tropen from UC - DOM Trooper is from Gundam Seed.

RGM-79SP GM Sniper II - Both HG and MG kits for GM Sniper II exist, though don't mix it up with the regular GM Sniper - that one's from The 08th MS Team and looks considerably different.

MSN-04 Sazabi - Sazabi got an RG release in 2018 and it's a very impressive kit.

The recent HG kit of Char's custom that came out a few months ago has a lot of detail for an HG kit and can be easily found (Target had a plethora of them months back), while the MG 2.0 kit is still considered a gold standard as far as MG kits go.

MS-06 Zaku II - Like Grandpa, the Zaku II comes in multiple flavors of kits to choos from.

If you've got the cash, the PG Unleashed kit is absolutely incredible.

If you want something bigger, the MG 2.0 is pretty good and is close to the anime model (the 3.0, while detailed, can be finicky). It's inexpensive yet is one of the best HG kits around. RX-78-2 Gundam - Being the grandaddy of them all, kits of the RX-78 exist in every grade offered by Bandai.While the site is in Korean, an English option exists as well. Virtually every Gundam model kit that has been released (and then some) is documented there. For future reference, is one of the best resources for Gunpla kits.
