The fanciest gunpla - My first HG, and still my favorite.
TL;DR: Beargguys are cheap, adorable, easy to build, look great on any shelf, and are a bit bigger than your average HG.
Pros:
-Fancy
-Adorable hat, cane, and mustache
-Multiple facial expression options
-Movable mouth
-Arms replaceable with extending versions.
Cons:
-Despite fitting snugly, the Acguy's neck joint is pretty weak for holding up something so big! Be careful!
-Acguys and their variants have bad poseability
-There's only one face plate, so you have to choose what expression you want and you're stuck with it (I built mine two years ago, so I might be remembering this wrong!)
-On a personal level, I've always wanted the kits to come with some beam sabers for use with the particle cannon.
