when leobreaker and optimus combine for savage claw modefor the very first time is it just me or does leo prime actually pull of a clear homage to domon kashues shinging finger attack from mobile suite fighter g gundam when leobreaker forms the glowing burning hand from his body ? check this out YouTube - Sonic Finger Sword! the first video provided the lines for the scene and needs to be set time wise at 005 secodns into the video while the second video shows optimus prime and leobreaker combine for the firsttime into leo prime and this video needs to be set at 015 seconds into the video so that when you start playing it the scenes from the second video should be properly synched to the domons lines in te first video get the timing down just right and wow man
Eh, I just thought it was a generic super robot attack. I'm sure it's been done before but I never spotted a homage.
the combination is a huge GaoGaiGar nod from camera angles to the timing. But for the attack itself... I dunno glowing fist attacks are common in anime.
