4. Kang The Conquerer (Marvel Comics)
Kang the Conquerer is a massively underrated character who, despite a common opinion to the contrary, is very powerful indeed and boasts a vast array of powers. Kang has been troubling super-powered heroes like the Avengers on the pages of Marvel comics, in a way that few other villains have managed, for fifty years. He's from an alternate timeline to the main "616 universe, where he is related to both Reed Richards and Victor Von Doom two characters whom he rivals on an intellectual level, which is something only a handful of beings in fiction can lay claim to doing. Boasting an armoured suit that completely surpasses that of even Iron Man and Doctor Doom (the latter who actually admitted that Kang was his superior when it came to technology), Kang possesses superb durability, as his armour is made from alloys found in the 40th century, enabling him to tank shots from Thor's hammer Mjolnir (even when Thor is in Warrior Madness mode). He can also survive in space in the suit and survive re-entry. The suit is capable of shape-shifting, control over magnetic fields, knowledge absorption, extremely powerful energy blasts (enough to kill characters as powerful as the enormous Tempus), energy manipulation (even magical energy, as he sent a spell back at Merlin when the sorcerer attacked him), hologram projection for the purposes of things like illusions and force-field projection in order to augment his durability further (which has enabled him to survive the planet-busting energy blasts of the Silver Surfer). It also contains in-built time powers that enable Kang to time travel, freeze time or dump an opponent in a different time at any given moment, as well as flight capabilities, a teleportation device and telepathy proofing against mind-attacks or psionic probing (such as when Mantis was blocked from entering Kang's mind). Interestingly, Kang's armour also has a thirty day supply of air and food. Essentially, Kang has all sorts of weird powers at his disposal, thanks to his armour - and we haven't even covered everything.
