I recently bought Masterpiece Rodimus Prime from Toys R Us and only had to spend like $15 bucks to get free shipping. I figured why not get this two pack for $16.99 when shipping was going to cost me $8 for just Rodimus so I added this 2 pack to my cart. I do not regret almost paying $20 for these guys. I only wish these guys came with figure stands like most of the Marvel Universe today.
I've always liked it when a super hero/hero team has to fight an evil version of themselves. Something along the lines of "A person's greatest foe is themselves." When I was a child my favorite was when the Power Rangers had to fight evil Doppelgangers of themselves but Dark Spider-Man and Dark Wolverine are a little more awesome because they have much larger back stories.
