So er, long way to go, obviously, but I figure Onslaught is a good choice. Having seen that custom Jallguar that was made by @omochasouko02 on Twitter, I figured using Onslaught's legs for the rocket launcher that is one of her notable features, is a good idea. @SteamShield makes a cracking set of rocket launchers that double as combiner knees, and I'm pretty happy with how they look. Needing new heads and chest panel, obviously, and obviously it'll need near enough a full repaint, but I'm hoping this will really work out. Plans to give her additional panels to give her the proper robot mode look too, especially the boat-wings she typically has.
