Jatsuk(ジャシクJashiku) is a forest planet home to a race of brown creatures with an exceptional talent for crafting and repairing machinery. It is the home planet of Diesel. First mentioned in Volume 1 of Samus and Joey, it does not make an appearance until chapter 4 of Metroid EX, when Diesel and his friends Samus Aran and Joey Apronika crash-land here. Diesel had previously been seen inhabiting a large space station and working out of a junk shop he had there, the Junk Quixote.
