Characterization
As a young man, Joseph is incredibly hotheaded, impetuous, and confrontational. He is not very serious or focused, and he tends to fool around. Despite his attitude, he is also very intelligent, defeating much more powerful opponents through clever tactics, and even able to accurately predict an enemy's next line (his catchphrase being "Your next line will be..." or "You're going to say...") However, over the course of Part 2, although he never really loses his overall attitude, he does develop into a strong, focused hero. At crucial moments of battles, he likes to predict the next sentence of his opponents. In Part 3, he is much the same, only as an irascible old man with a temper and the same mischievous spirit as in his younger days. However, being older, he is certainly more mature and serious.
His catchphrase (used often in Part 3) is, "Oh! My! God!". Sometimes this will alternate with "My God!" or other such variations. He also shouts "Holy shit!" in at least one instance in the Japanese release of Stardust Crusaders.
