6. Lex Luthor (DC Comics)
Superman's arch-enemy Lex Luthor is a very astute prep-master - particularly in his pre-crisis form - and one who has created technology far in advance of anything Batman has ever created. As a general rule, all incarnations of Lex Luthor have created battle-armour that is capable of at least making a fight of it against Superman. When wearing the armour, Luthor gains a high degree of protection against attack. Even the apparently exposed head is protected by an invisible full body force-field that is good enough to completely block energy blasts and resist superstrength punches. Without the force-field, the armor can be wrecked by high level physical attacks, although it is still bulletproof and capable of offering protection against lesser physical attacks. The power armour also enhances the wearer's strength and carries an array of in-built weaponry. These weapons range from wrist-mounted machine guns and shoulder-mounted rocket launchers to the advanced, long-range energy guns and short-range, wide-beam energy projectors. The Apokoliptian computer systems that control the armour (which Lex could understand and develop further - an impressive feat of intelligence in itself) read the mind of the user and react at the speed of mental commands. It is also capable of flight and contains a single use short-range teleporter that will send the pilot to the closest safe location it can detect if there is risk of the user suffering lethal damage. In addition to this kind of technological ability, Luthor showed that, in pre-crisis continuity at least, he could build advanced technology using - quite literally - rubbish. Whilst imprisoned, he used orange juice cans, a piece of spring and a lightbulb to make a fully-functioning time machine - that is well beyond anything Batman is capable of building. Luthor also possesses political planning skills that have seen him become the President of the United States of America, despite the fact that he is essentially evil.
