Mine would be best conveyed with a snippet of my character's backstory.
In Orrin Morin's effort to uncover whether Dunesfolk in Ul'dah treat plainsfolk any differently than they treat one another, he hurriedly chose what he believed to be a suitable Dunesfolk name before donning a magical disguise. Unfortunately, "Momoji Momochi" is actually two dunesfolk female names put together, as he soon realized to his embarrassment. Even worse, he failed to read the warning that the removal potion for the magical disguise was highly sensitive to aetheric disturbances, which due to a series of events rendered his only method of removing the disguise worthless!
So Orrin Morin, now Momoji Momochi, set out on a quest to acquire another removal potion. Through feats of daring, such as constructing a giant sand castle for suitably giant ants, and entertaining a giant buffalo, he finally removed the magical disguise. How that removed a magical disguise is an entirely different story.
Unfortunately, his acts of daring had galvanized his name in the public eye, and now people can't stop calling him Momoji Momochi! His plan to solve this predicament? Make himself so famous that by merely announcing that his real name is Orrin Morin, everyone will begin calling him that instead! And so he continues with his adventurers, saving kittens and pouring laxatives into imperial water supplies, the later being a very time consuming effort. Take that, you damn imperials! When you reach the steaming hell known as "the lavatory," tell them Momoji Momochi sent you!
Edit: If that isn't the weakness you are looking for, then his kryptonite is chocolate pudding. Delicious, delicious chocolate pudding. He'd call down a meteor for the stuff.
