5. Darkseid
Darkseid is one of DC's best and most powerful villains. He is visually imposing, a huge physical threat, a technological genius and commander of a legion of super-powered followers and minions on his native Apokolips. He is often considered to be a Superman villain, but has on numerous occasions proven himself more than capable of being a legitimate threat to the entire Justice League. He possesses vast superhuman strength and durability, as well as his devastating Omega Effect which has the ability to wipe those it hits from existence. A disappointing version of Darkseid appeared, albeit briefly, in a live action production when he was the final villain opposing Clark Kent in TV's Smallville, but fans would love to see more of him in a bigger budget flick. A lot of comparisons can be made between Darkseid and Marvel's Thanos (indeed, Thanos was modelled on Darkseid and, in the Amalgam comics universe, Thanos and Darkseid were merged to form "Thanoseid") and the anticipation caused by Thanos' cameo at the end of the Avengers should serve as ample incentive for DC to use the equally formidable ruler of Apokolips on the big screen. He has the fan-base, the character traits and the supporting cast of characters to make a movie focusing on him and his fellow New Gods extremely interesting.
