The Ion Cannon is an antiquated weapon used by Rocket.
History[]
One of the particular models of the Ion Cannons was a pump-action weapon chosen by Rocket as his favorite weapon.
However, after visiting The Hub, he was forced to sell it to obtain some money. As a new model known as I-Ex 50 came out, the model in Rocket's possession has become outdated, and he only obtained 30 Credits for the transaction.[1]
