Ozymandias
Ozymandias might seem like an odd addition to this list – not least because he exists in a world that doesn’t really have too many powerful characters – but he has undoubtedly proven that he is wise enough to use nontraditional methods to defeat characters he should have no right to defeat.
It is his genius that makes him a threat to anyone he encounters – as proven when he posed a threat to Doctor Manhattan himself, in spite of the fact that Ozymandias is merely human and Manhattan is essentially a god.
Ozymandias is capable of using psychological manipulation to wear his targets down mentally, without actually getting into a conflict with them – and without their even knowing that they’re being worn down. He is also capable of creating devices that can harm even Manhattan himself – such as the one that turned him into atoms. Manhattan was, however, able to reform.
