Bumi is known for his eccentric and unpredictable personality. This often leads his enemies and even his own subjects to underestimate him. However, beneath this quirky demeanor, Bumi is a brilliant strategist. He always thinks ahead and waits for the perfect time to strike, a trait that enabled him to take back Omashu single-handedly during the Day of Black Sun. He also masterminded a strategy that allowed Omashu to defend itself while also supplying Earth Kingdom forces in other regions during the Hundred Year War. His leadership style reflects his belief in keeping one's mind open to all possibilities.
