Who would win? Their both deadly, but I think Starscream would man-handle Blackout. He's smarter, quicker, and his saw blade could probaly take off some limbs. You guys saw when Screamer hit Grindor with his missles, Grindor got pieces blasted off! The only Blackout could when, is if he hits Starscream with his emp blast, or his rotors. So, if these to were to fight, who would beat who. Side note: Lets pretend that the fight they had in the comics, never happened ok Now, let us discuss.
