As a master of the Ripple, Zeppeli is confident and brave, notably thinking that one's courage is proportional to the hardships one faces.[3]

The Ripple master notably keeps a methodical and cool approach to battle despite the horrible fighting styles of the enemies although his experience may help. For instance, he tries to teach Jonathan to put himself in the enemy's shoes to predict their actions.[4] Having been predicted his death by his master Tonpetty, Zeppeli bravely walks toward his demise and sacrifices himself to help Jonathan. Ultimately, Zeppeli was strong-willed enough to crawl toward Jonathan despite having the lower half of his body cut off.[5]
