Shredder vs Dr Robotnik

Note
Before this battle begins, I would like to commemorate the two voice actors of these characters of these characters who passed away. James Avery, the voice of the Shredder in the First Teenage Mutant Ninja Turtles cartoon (1987-1996) passed away on the 31st December 2013, and Long John Baldry, the voice of Dr Robotnik in Adventures of Sonic the Hedgehog (1993-1996) passed away on the 21st July, 2005. A huge respect to these two legends for bringing these characters to life and forever brightening the childhoods of many with their amazing performances. You will always be remembered fondly :)
