I'm enjoying my Leader Ironhide but I find his arm cannons to be a bit small and I'd like to make him more DotM-accurate by giving him two hand-held guns. Bonus if they can store easily on his back, pinned by the kibble or using the MechTech ports on the shoulders. So far I've used Sideswipe's MechTech and it looks good. I think Voyager Prime's gun might work, but I don't have him.
I remember deceptigtar posting some awesome pics of leader ironhide with HA backfire. Backfires are $10 but I think they look pretty sweet. this isn't his just another one I found using google image search. not sure who the owner is, but it looks like he's got a custom dotm voyager prime gun too.
I have him with HFTD Ironhides guns in his back and him holding the helicopter HA figure that turns into kind of a minigun
Posted this pic a while ago. Leader Ironhide does not hold up the Backfire twins well. His arm joints are weak to the weight and they fall easy in his hands... However on his shoulders they look geat and the scale goes well. The twin hand cannons are Lazerbeaks(2 guns one figure.. WIN WIN).
