Nyobo Staff

Goku recieved the Nyobo Staff (Power Pole) from his Grandpa Gohan. This pole is unbreakable and can extend into infiniti. The original creation of this pole was for it to connect Karin's tower to Kami's palace, and Goku uses it to travel from one to the other a few times before he learned how to fly.

In DragonballZ, Goku rarely used this weapon except for the very early episodes and movies. He eventually gave it to his son Gohan.

Kinto'un

After helping Umigame find his way back to the ocean, Umigame travels off and brings back Muten Roshi. As thanks for saving the turtle, Muten Roshi gives Goku the Kinto'un, a magical cloud that only people with a pure heart can ride on. If the person trying to ride did not have a pure heart, they would fall right through the cloud. If the person's heart was pure, the cloud would become solid for them and would obey their commands. A cool thing about the Kinto'un is that you could call on it from anywhere. 

Kaioshin Crystal

This Crystal Ball belonged to Rou Dai Kaioshin and served a lot of purpose for the Kaioshin to see what was happening throughout the universe. We first see this ball after Rou Dai Kaioshin is released from the Zed Sword. He creates the crystal so they can watch the battle with Majin Buu that was taking place on Earth. After that this crystal was used a lot throughout GT.

BaBa's Crystal 

During the fight with the Saiya-jin, all the onlookers at Muten Roshi's house watched the battle through Roshi's sister Baba's Crystal Ball. The refresh rate on this ball wasn't very great and it was also greatly affected by the power that Vegeta and Goku were letting off. Because of this, Chi-Chi became extremely aggrivated with the crystal and threw it on the ground, causing it to break.

Potara Earings

Every Kaioshin wore a pair of earings called Potara. The only purpose known for these was the fusion aspect of them. If taken off of a Kaioshin and placed on the opposite ears of two different people, their life forces would be sucked together, creating a brand new warrior with combined aspects of both people. The only person we see fuse with these is Vegetto.

Chosinsui Water

Out of desperation to defeat Piccolo, Goku drank some of the legendary Chosinsui Water that was kept on Karin's tower. As legend said, this water could bring out the true potential of a person if they were already strong physically and mentally. If they didn't meet these requirements, the water would be poison to them and they would die. Before Goku's success, noone was known to have succeeded in drinking the water and 14 martial artists' were recorded as dying in the attempt.

Black Water Jar

During the Garlic Jr. Saga, Garlic Jr. opened the Black Water Jar, releasing the Black Water Mist onto the Earth. The mist caused all people that breathed it in to turn evil and destroy the Earth. Luckily, Gohan, Kuririn, and Piccolo never breated in the mist and were able to defeat Garlic Jr.

Basho-Sen Fan

This ancient relic was made out of a palm leaf and had magical powers. The Basho-Sen Fan could create a powerful storm by simply waving it once, a giant thunderstorm by waving it twice, and a monsoon by waving it three times.

Master Roshi had kept this in his house as a floor mat but threw it out after he spilled juice on it causing it to become sticky. It was never shown being used until the end of Dragonball when Goku had to put out a giant fire.

Music Box

The legendary warrior Tapion was sealed inside this box and sent to Earth so that the demon Hirudigarn would not be released. The black magician tricked Earth's Warriors into thinking that something good would happen, so they used Shenron to open up the Music Box, releasing both Tapion and the demon monster Hirudigarn. After Hirudigarn was defeated, Tapion was sealed back up inside this box for safe keeping.

Senzu Bean

On Karin's tower were grown the Senzu Beans that had magical power to heal any wound and restore all ki power. These were vital to the success of the Z Warriors all throughout all three series.
