Mysterious Joker (怪盗ジョーカー)

Joker is childish most of the time, but he can also be mature when a situation gets serious. He is very smart and uses it to confuse and trick his enemies. He loves to eat (his favorites being curry or hamburger steak), and loves Hachi's cooking to the point where he describes it as "best in Japan". He has a pretty high sense of loyalty towards his "profession" and he sometimes exaggerates it to lure his enemies into his traps and doesn't hesitate to feign throwing his pride away and act desperate even though he knows he's already won. With a sadistic streak, not only does he like to fool his enemies with tricks, but he also takes glee in the occasional mind game (which, while can get quite mean, has limits in cruelty). He is shown to be lazy and disorganized in daily life, unable to cook for himself and unmotivated to clean.

Despite shown selfishness, Joker has significant compassion towards helping others, not easily able to accept criminals or rivals threatening innocent people for their plans (even when he may complain about how phantom thieves "don't help people"). He isn't completely averse to pairing up with others for the greater good.

Joker usually wears a dark blue hat with a blue and white checkered strip, a blue shirt, a yellow tie, and a red suit with a golden J badge on his chest. He also dons a purple cape, dark blue shoes, white gloves, and a light purple eye mask.

In certain occasions, such as traveling or steal the great treasure of some country, he'll take off his mask and red suit and wear black suit, or disguise as an local people.
