SD Gundam Cross Silhouette Zaku II

Ironically it's got nicer details than a lot of other Zaku II model kits. The 'jewel' sticker eye especially is a really nice touch (it's a shiny pink sticker with a gel drop on top of it, so it's raised).
Kit comes with a nicely detailed rifle, bazooka, twin rocket pods for the legs and a heat hawk (axe) with a cool transparent edge, something that none of the other Zakus I own have. You'll have to get the PG to get the same :D

Finally it's a 'cross silhouette' compatible SD kit, meaning you can buy a separate inner frame with longer limbs and elbow/knee joints instead of the stiff limbs (which I have). It doesn't give it a ton of height, but it does give it just enough posability to put it in some cute poses that aren't as limited. I only have 3 SD kits, but this is the nicest one by far.
