10. Gorilla Grodd
Ok, so this one might be a little tricky to pull off, but it would be a real shame to not see the fearsome Gorilla Grodd in The Flash’s latest small screen outing. Special effects equivalent to those seen in Rise of the Planet of the Apes are obviously a pipedream for any TV series, but it’s not really all that difficult to imagine a character like this (and his army) being brought to life through the use of practical make-up effects which are then enhanced by CGI. Like the majority of DC characters, there have been many different portrayals of this villain over the years, thereby giving the team working on The Flash plenty of material to work with. The latest has shown Grodd as the maniacal leader of Gorilla City, although a confrontation with Barry Allen would later result in him becoming obsessed with the Speed Force (the extra-dimensional energy force which gives The Flash his powers).
