This weapon is of a bulky, rounded shape, usually yellow in color with an orange barrel and a red cover for the ammunition slot. It is notably the smallest version of the plasma weapons and was first used by Stitch after he crash landed on Earth in Hawaii.
A larger model first used by Jumba when trying to capture Stitch. It is easily twice the size of the Mark I and possesses a large protective red cover over the top of the weapon with a small orange fin jutting out of the top. Plugging the barrel causes the weapon to enter a meltdown sequence lasting approximately one minute before it detonates in a large blast of plasma.
Seen in the possession of the Leroy clones, this is clearly a more accurate model of the Mark I. It features a longer barrel covered in holes for a faster cooling rate. It also has a longer, red handle and an orange fin on top, similar to the Mark II.
