I've never been that keen on the XV8's design. The newer version is at least poseable but the suits look so gawky and goofy like the tow truck in the "Cars" films, IMO.
I far prefer the XV9's which look like they want to shoot you rather than sing kum-by-yar and toast marshmallows round the campfire with you.
...but then again, maybe that's what the Greater Good is all about??
