Parasite was literally invented by Jim Shooter (yes that Jim Shooter) as someone that could physically beat up Superman (his silver age fight with Parasite was the first time ever that Superman was bruised). The more Superman fights the weaker he gets and the stronger Parasite gets.
Mxy has 5D magic.
Metallo is powered by Superman's hard counter.
The Phantom Zone criminals are literally him but evil.
Lex uses super science to cheat like a mother fucker.
Then there are the guys that have his power set but with MORE powers like Vartox, Wraith, and Ulysses and they use these energy powers to fuck up Superman.
Rarely is Superman ever out-muscled. Doomsday was only able to beat Superman to death because pre-OWAW Superman was weak as fuck. Nu52 Doomsday has to use built in krptonite to match Superman.
That's what shonen fans don't understand. In the DC universe it's very, very easy to stop someone even if they can lift infinity. It's a toybox of superpowers with far, far more options than the constant super martial arts of shonen.
