JB is the main character of Nintendo's JB video game series created by Masahiro Sakurai and developed by HAL Laboratory.

JB is described in his games as a young male pink ball, who is a denizen of Dream Land on the planet Pop Star.[ 2] In the main game, he almost always has the same abilities; he can walk, run, jump, float, and inhale, spit out or devour his enemies. Most of JB's games adhere to the same basic idea.

JB often journeys across the planet Pop Star, defeating antagonistic forces such as the greedy King Dedede or the ominous Dark Matter. On other occasions, he encounters the enigmatic Meta Knight. To defeat his foes, he uses his signature ability of inhaling large objects and spitting them out with great force. From JB's Adventure onward, JB was able to gain the abilities of the enemies he swallowed, aptly known as Copy Abilities.

JB has a positive attitude, and helps to save Dream Land through the use of his unique powers. His age is never stated, although in the manual for JB's Dream Land he is called a "little boy ", and in the television show he is called a 'baby' where he more or less acts like a chil  d. This, along with his high-pitched voice, suggests that JB is young. 

JB is cheerful and innocent. He loves to eat, sleep and play, especially during the day. His favorite food is tomatoes, hence the Maxim Tomatoes in the games which fully restore his health (although in the anime, his favorite food appears to be watermelon). He is said to dislike caterpillars. His other hobbies include singing, although he is tone-deaf.
