Joules is the name of a Tazerling slug who used to belong to Shockwire. Eli Shane won Joules from him after defeating him in his first duel. He is a happy go lucky, excitable slug who is almost always in a good mood. Joules is the third slug Eli obtained (second being Noodle).
Joules debuts in The World Beneath Our Feet Part 1, where Eli Shane wins him from Shockwire.
