If you don't know about Kaituo Joker? I'll give you the Phantom Thief's equipment...

Image Gum; Image Gum is a pink, ordinary looking gum, that was created by Silver Heart and is one of Joker's tools-of-the-trade. It has the overall ability to transform him and anything else by matching the shape, rigidity, for five minutes, and the appearance of anything the user has seen the object or person at least once. It should be noted that in the manga, Joker uses it in a similar way to Balloon Gum.

Balloon Gum; Balloon Gum is an anime exclusive tool that looks identical to image gum other than its green color. It was also another tool-of-the-trade created by Silver Heart. Balloon Gum is used to either float in the air for escaping and pursuing foes like Phoenix.

Speed Balloon Gum; is an addition to balloon gum that was introduced in season four. It seems to work similarly to regular balloon gum, only it's faster.

Playing Cards; Joker's cards are another of Silver Heart's tools-of-the-trade. They are his primary arsenal of choice in battle and along with various uses from Joker's cunningness. They are fire proof, and extremely durable, due to being able to cut through metal and a number of other things. Joker uses his cards in a number of ways depending on the situation at hand.

Straight Flash; Joker's primary signature move when he makes a straight flush hand which creates a great flash to temporarily blind foes.

Royal Straight Flash; an upgraded alternative of the above while also pulling off other moves like Emblem Fire or Flying Explosion. Introduced in Season 4.

Emblem Fire; is a technique where fire wraps around on of Joker's cards. Whether the card automatically does it or Joker does is unknown. Along with Royal Straight Flash, he can use Emblem Fire to pull off.

Flying Explosion; was newly introduced in season 4 when Joker combined Royal Straight Flash and Emblem Fire. A ring of fire circles around Joker as he floats in the air. Then a flurry of flaming cards rain down scorching and denting several robots.

Shooting Star; is a technique where magic wraps around a card that Joker throws. Again it is unknown whether the card emits it or Joker applies it to the card. This ability is rarely used.

Final Shooting Star; a stronger version to the above.

Shuffle Shoot; is a technique where Joker shoots a flurry of cards at an opponent.

Wristwatch; summon Sky Joker, Road Joker, attaching thread on objects, flashlight function, tell time as a normal watch, magnet function, communicator.

Sky Joker; Joker's massive airship and personal headquarters. It is also Joker's personal residence followed by Hachi and Hoshii after. Joker stores all of his treasures in a hidden large room. Hachi also has a room with a garden in there as well. It is stocked with a kitchen, bathroom, bedrooms, and many other rooms. Joker can also summon it via his wrist watch. Joker's airship is more blimp-like in the manga.

Road Joker; Joker's personal automobile for ground and sea transportation. The steering wheel has a wheel-panel of numbers, each carrying a different function. The main one shown is the button that makes the car launch up in the air. He first used this ability in the first episode of season one.

Joker Vision; Joker's high-spec goggles with x-ray vision, heat-seeking, night vision and other scanning capabilities.

J Pin; An emergency pin to create a smoke screen as means for quick escape. In the manga, he also hides a piece of image gum in his J as a last resort.
