If it weren't for the aid of signature moves, the Z-fighters would have found themselves in inhospitable circumstances. Luckily, there are moves like the Kamehameha, Special Beam Cannon, and Spirit Bomb that have saved the Z-fighters time and time again.

Signature moves can be used to protect lifeforms in the universe, or they can be used immorally. Frieza's signature move, the Death Ball, is responsible for destroying Planet Vegeta and the Planet Namek. Whether they are used for good or evil, signature moves are the most powerful attacks that a Dragon Ball fighter can summon. Let's take a look at some of the strongest and most iconic.

10 Final Flash

We know Vegeta uses this as his last-ditch trump card. Brought to the edge of his limits, Vegeta erupts in a frenzied attack known as the "Final Flash." Only in the most desperate situations does Vegeta cross his boundaries.

We've seen Vegeta use the Final Flash against Cell and also in Dragon Ball Super. Sporadic bolts of lightning surround Vegeta as he charges the attack. Had Vegeta launched the attack directly at Earth, it would have meant the end of the pale blue planet as we know it.

9 Masenko

Even at a young age, Gohan was able to keep up with fierce fighters like Goku and Vegeta. He proved that age isn't as important as one's potential and willpower. We saw Gohan's hidden power become unlocked when he visited Grand Elder Guru on Namek.

In combination with his mysterious power and a move like Masenko, Gohan has saved those who need saving. He must have learned the move from Piccolo during his training on Earth.

8 Special Beam Cannon

All these years, Piccolo has managed to keep up with the Z-fighters despite beating impossible odds as a Namekian. Fusing with Nail, Piccolo became what is known as a "Super Namekian." The powers of a Super Namekian are comparable to those of a Super Saiyan.

We can't forget Piccolo's enigmatic signature move. He is the only known user of the attack, other than copycats like Cell. In the most desperate times, the Special Beam Cannon can place the Z-fighters in a more auspicious situation. Its power can push past the limits of many Saiyans, and its power capability is exponentially large.

7 Destructo Disk

Comparable to Frieza's Death Saucer Ki Blast, it's Krillin's Destructo Disc. How a human like Krillin can summon power similar to a Super Saiyan has most people lost for words.

Moreover, using the Destructo Disc, Krillin can cut foes more than one hundred times powerful than him in half. It can slice through almost anything, which is why it is considered one of the most powerful attacks on this list. The downside to the move is that it's very slow and can be detected by enemies unless they are distracted.

6 Chocolate Beam

Widely known as the "Chocolate Beam," this move has the power to turn a foe into any object. Majin Buu turned a ton of Earth's inhabitants into candy, which is likely why it is referred to as the Chocolate Beam.

Majin Buu did, however, use the move to build his clay house. Majin Buu seems to have good intentions, but sometimes his actions are devious and reprehensible. Majin Buu could have found clay, for instance, but decided to turn people into clay instead.

5 Galick Gun

Goku nearly destroys his body trying to combat the merciless Vegeta in the first season of Dragon Ball Z. Although we rarely see it, Vegeta will use the Galick Gun when his real power is tested.

Once again, we saw Vegeta fire the Galick Gun in Dragon Ball Super and again later in the series. Galick Gun is described as a blinding purple light. It is less powerful than Vegeta's Final Flash, but still a devastating signature move.

4 Kamehameha

Time and time again, Goku's Kamehameha saves the day from those trying to bring harm to the inhabitants of Earth. His powerful Ki Blast grows in power throughout the series, with Goku having the power to dissipate an entire planet (and possibly a galaxy) with a single charge.

It's the most common recurring ki blast in Dragon Ball Z, which is used by multiple individuals such as Cell, Buu, Gogeta, and Goku. Notably, Akira Toriyama tried a few poses in-person before designing the Kamehameha.

3 Death Ball

As the self-declared emperor of the universe, Frieza's ruthlessness was what lead to his downfall. Instead of admitting defeat to Super Saiyan Goku, Frieza hurled a variation of the Death Ball into planet Namek's core. With an unstable core, destruction of the planet became imminent.

Despite Frieza being one of the most repulsive characters, his Death Ball move deserves recognition for being a momentous Dragon Ball signature move. Frieza's Death Ball on Namek became a major influence on the events of Dragon Ball Z.

2 Eraser Cannon

To find out that there was another living Saiyan was quite the surprise in the movie Dragon Ball Z: Broly – The Legendary Super Saiyan. Although he was quiet and well-mannered when Goku and friends arrived, Broly changed into the opposite later in the movie.

Broly is one of Dragon Ball's most memorable characters, with his unique moveset and dominating power. His Eraser Cannon is one of the most powerful in Dragon Ball Z. Blinding green light in the form of an energy sphere emanates from the Eraser Cannon, leaving a path of destruction in the wake of its usage.

1 Spirit Bomb

Credited for being the signature move that has saved the Z-fighters numerous times, the Spirit Bomb is a move that is used exclusively by Goku. Learned from King Kai, the power of the Spirit Bomb is drawn from the energy of all living things in the universe, creating one attack with extraordinary power.

This signature move was used against foes like Frieza and Vegeta. Depending on the number of lifeforms it draws energy from, the Spirit Bomb can be one of the most powerful attacks in Dragon Ball.
