He seems like a pretty spot on Dodge Tomahawk to me. Not sure if that quite fits with his police bike origins though. Still it may end up a good choice in order to get a decent sized leg for Defensor. I'll reserve judgement till I see a colour version.
It's interesting how Uranos other than Blackbird all used the same alt mode as the Aerialbots they were based on, while these guys seem to have traded there's for recent models.
