THUNDERBOLT CHALLENGE "4piece" is an audition program organized by Thunderbolt Entertainment. Commonly known as "4piece", the program will judge idols at four different venues over the course of a week, in order to form a Dream Unit that will take flight around the world. Many idols aim to find success through "4piece", so that they can become "Children of Hope" who will carry the future of the idol world.

==Logo==
4piece's logo consists of the word 4piece in a sharp serif font with sharp details that make the letters look like they have lightning bolts coming out of them. The number '4' is coloured in bright yellow and is separated into two lightning bolts, the undermost one having a purple outline and the one on top having a teal outline. The number has an additional dark blue border. The word 'piece' is written in white with the top part of the outline being turquoise and the botton part being pink. There is an additional dark blue outline. The umlaut(circle) of the letter 'i' is shaped like a five-pointed star in golden yellow and has the same outline as the rest of the word. The letter 'i' is shaped like the number '1'. There is an additional teal drop shadow under the dark blue outlines of 4piece and a white outline to seperate the words from the background details. The word 'piece' is on top of 4 differently colored spiky marks which are shaped like comic styled explosions. The bottom left one is pink with a turquoise drop shadow, the top left one is orange with a yellow drop shadow, the top right one is turquoise with a pink drop shadow, and the bottom right one is yellow with a purple drop shadow. All four marks have a white outline. On top of the turquoise mark are the words 'THUNDERBOLT CHALLENGE' in a white sans serif font and tilted towards the center of the logo, the words have a dark blue border.
