4. Clark Kent (Smallville)
Smallville's Clark Kent was incredibly powerful - indeed he's the most powerful character on this list by some distance - but he was still nowhere near as powerful as the classic comic book versions of Clark Kent/Superman, particularly the pre-crisis version. The Superman that comic book fans are familiar with has, over the years in various different eras, juggled planets, towed a row of planets, bench-pressed the Earth for several days non-stop and caused planets to crack as a result of his fights. He has moved at lightspeed and his thought process has operated within nanoseconds. His durability is such that he can walk away from being at ground zero of a nuclear explosion completely unscathed and take punches from people who can destroy planets without being killed. His heat vision in the comics has been described as hotter than the sun and has been wide-angled enough to cover an entire planet. Smallville's Clark Kent, in the end, did move a single planet (pushing Apokolips away from Earth), but it was a struggle for him and still not close to the comic book version's best strength feats. His speed was incredible - indeed the normal world looked almost stationary to him at his fastest - but this still isn't close to the beyond-lightspeed travel that the comic book version has shown. And the Smallville version certainly didn't think within nanoseconds like Superman has done even in the post-crisis comics. His durability was also never shown to be as high as the comic book version and neither was the level of his heat vision - though the latter was still particularly impressive in Smallville. So, to reiterate; Smallville Clark Kent is indeed extremely powerful but, when compared to the Superman of the Silver Age and Bronze Age of comics, he's not even close.
