In Super Robot Wars games
Was it ever clarified if the FS having a larger heat hawk is a retcon, or just something that specific units had? Most older depictions of the FS have the standard heat hawk, even on Garma's FS (even as recently as Journey to Jaburo and Lost War Chronicles on the PS2). More recently, Garma's is shown to have the larger heat hawk, as well as Shin Matsunaga's. I can't tell if this is supposed to suggest that it was a custom feature used by certain pilots, or if it's been retconned to be standard on every FS.
