Mario Zeppeli

Mario Zeppeli (マリオ ・ ツェペリ) a character briefly featured Part II: Battle Tendency. Father of Caesar Anthonio Zeppeli, he's characterized as hard-working, trustworthy, and a wholesome family man.

History
Sometime during Caesar's youth, Mario would leave his five children without telling them about his investigation on the Pillar Men, earning him the hatred of his eldest son.

Years later, Mario would head to the site where the Pillar Men were discovered, unknowingly trailed by his bloodthirsty son. When Caesar stops to pick a jewel from the wall, Mario saves him by pushing him out of the way of Wamuu's trap, and becomes absorbed into the wall. Before he's absorbed completely, he tells his son to report his death to his colleague, Lisa Lisa, as she was the only one capable of rivaling the creatures. This selfless act earned him Caesar's admiration post mortem, and caused him to seek revenge against the Pillar Men.

Ripple
Unlike Caesar, Mario had known since he was young of the fate of his father, Will Anthonio Zeppeli. Because of this, he had researched the Stone Masks, and was able to find the Pillar Men long before Germany's discovery. Since then, he had been travelling the world in order to discover a way to destroy the creatures that were in the wall. Though he had not been shown using it, Mario had spent his life training his Ripple, following in the footsteps of his father.
