So, Goku had to face Frieza and see Krillin get killed before he became a Super Saiyan. Turns out, all he needed was a little hot water. At least, that\'s the case with this Dragon Ball Z Goku Heat Change Mug! Made of ceramic, this mug is brilliant quality and holds around 300 ml. It\'s officially licensed Dragon Ball Z merch and features a fantastic graphic of Goku which is where the real magic comes in. When cold (doesn\'t have to be straight out of the Frieza or anything room temp will do), it features Goku in his power-up pose. Then, when you fill it with hot liquid, it magically manifests an energy glow around Goku! Saiyan power can stand up to most forces that oppose it except the dishwasher. So, it\'s best to wash this mug by hand if you want to keep it looking perfect. Just Saiyan. Your morning cuppa powers you up and does the same to Goku! So, for a Dragon Ball Z collectible that\'ll satisfy your thirst for fan merch, and just satisfy your thirst, order this Dragon Ball Z Goku Heat Change Mug today! | Dragon Ball Z Goku Heat Change Mug
