Darkseid
Darkseid is basically DC’s version of the aforementioned Marvel villain Thanos and, therefore, everything that applies to the Mad Titan applies to the ruthless Lord of Apokolips.
In fact, it’s generally considered that Thanos is a copy of Darkseid and was created in his image by Marvel’s writers. As such, he is every bit as powerful as Thanos and every bit as intelligent.
Darkseid has the physical might and the intellect to make him a threat to even the most godly of characters. He also has powers like the Omega Beams, which, when they’re written at their most powerful, can literally cause any target they hit to cease to exist – and the fact he commands a planet-sized army helps his cause massively as well.
