I hope some 3rd party or other is already making a good weapon for Thundertron, but even without one he's a definite buy. Magnus is very much Animated Magnus for a Classics collection, IMO, just like RTS Lugnut or Prime Bulkhead. That's not a bad thing, by any means, I love the hammer concept. Not 100% sold on the figure though. Not really liking the vehicle and robot mode is, yes, a bit bland looking.
