I love the idea that Megatron's flying won over Orion and he still turns in to a tank thing.
I... don't think any of that applies to these versions? Except the tank part, that is.It was robot mode flight that was new, wasn't it? Skyfire and Starscream were fliers who explicity predated the autobot/decepticon war.
I think the only reason to use Shadow Striker instead of Prowl would be if Kaskade isn't going to have a new head.Holy cow!
I'm guessing Kaskade is going to be a Shadow Striker recolor, but I dunno about Javalin.
