I ship them....

I know they're not even the same continuity/series/timeline but I do.

Both are hunters, both control a army of lookalike soldiers (All the TFP Insections pretty much looked the same and all the Sweeps were just duplicates of Scourge), both are Decepticons which in turns means they're both aggressive pricks.

IDK I just ship them.
Like... Scourge likes trying to play off that he's a 'mighty hunter, built by Unicron himself' but then he just follows Airachnid around like a lovestruck puppy.
