I'm not sure if I'm misinterpreting the intent (Is it meant to be a boss fight or just an excuse to get everyone together and finish the scene up) but...honestly, if it's the former, that really doesn't sound like a good idea to me unless you've got some non-mook reinforcements for him in mind. You've shown that his weapons are flimsy enough to be broken by a [s]glorified laser pointer[/s] lasgun, after all. If it's the latter...well, like I said, a bunch of characters have just transformed into their combat modes and one hasn't even reached that point yet, so...it feels like it's a bit early for that. To me at least.
