I really like him. I reckon he is very G1 faithful in robot mode (in fact a distinct improvement) and has an awesome Cybertronian alt-mode.
My son is loving his Weaponizer gimmick and has been decking out Siege Prowl and Soundwave with various combos.
I've had a play covering Metroplex with his guns. I love the fact that yes, he does hook up to Metroplex, but its just a shame that his guns are so small that in Plex's robot mode they are hardly noticeable.
What do people reckon the chances are of Brunt being recoloured into Slammer? Makes sense to fill out the trio of smaller bots for Metro, plus we all know Hasbro loves to get more than one use out of a mould.
