Oh...my...guns!  Sure we've already had a Ver. Ka MG Unicorn (linked below) and then the improved versions released when the OVA hit theaters in Japan (also linked below) but this might be the most epic MG Unicorn Gundam yet.  Just look at what's in this box!
MG Unicorn capable of transforming from Unicorn to Destroy Mode
Green psycho frame parts!
Two Beam Magnums
Two Hyper Bazookas
Two Triple Missile Pods
Two Grenade Launchers
Six Beam Gatling Guns (Yes, 6!)
Three Shields
Four Beam Sabers
Two Hyper Beam Javelins
If that isn't enough for you check this out.  Those Giant boosters on the back (along with extra parts supplied by Bandai) can be used to construct the Unicorns's Type 94 Base Jabber!
