In the topic "The most powerful superheroes in the world of comics" in the Forum section i have explained who and why this superheroes belongs in the list.
Bouth Gladiator and Shazam is of course two of the most powerful superheroes in the worlds of comics.
This is a very close battle i would love to see !
Shazam magical based Metahuman given powers from higher beings some even gods.
Gladiator a Super Powerful Alien who is more science based.
A battle of epic propotions with Shazam as winner in the end.
The Metahuman will be completely drained of power and needs a time for recover.
