Orange Piccolo Is The Special Beam Cannon Master
Debut Arc: Super Hero Arc
Orange Piccolo goes down as one of the most beloved transformations of them all. While the form itself is quite cool, the real reason why fans take to it so much is because it finally brings Piccolo, a fan-favorite hero, back into the forefront of the series as one of its main fighters.
He used this powerful new form against the Gamma Androids and Cell Max, where he showed exactly why it's so strong and on the level of the Saiyan's strongest states. Unfortunately, fans never truly got to his strongest attack, but judging by most of Piccolo's power-ups, his strongest attack in this form is likely also the Special Beam Cannon, as was also confirmed in the Dragon Ball: Sparking Zero video game.

Broly Can Refine The Gigantic Omegastorm Technique
Debut Arc: Broly Arc
When Broly made his canon debut into the franchise, his strength was shown to be immense, to the point where he was able to surpass Goku and Vegeta's Super Saiyan Blue states in his first ever proper fight. Although he lost his mind in his full-powered form, his strength was enough to even stand against Gogeta, albeit very briefly.
In his ultimate form, Broly used an attack known as the Gigantic Omegastorm, which clashed with Gogeta's Kamehameha. These two attacks were so strong that, together, they broke the dimensional barrier and sent both characters to a different plane of reality entirely. Now, with Broly finally gaining control of his powers, this move is pretty much confirmed to get stronger and even more refined along with the Saiyan himself.

Perfected Ultra Instinct Goku's Giant Form Is Incredible
Debut Arc: Galactic Prisoner Patrol Arc
Goku was the first of the main characters to unlock a powerful new transformation that went against the grain from what fans had come to expect from typical Saiyan forms. With Ultra Instinct, he awoke the legendary technique of the Angels of the multiverse, with which he utilized his incredible Spirit Avatar.
Essentially, this avatar is an outward manifestation of the energy that Goku receives from others, quite similar to how a Spirit Bomb works. However, instead of an offensive attack, Goku forms something similar to a mech made of spiritual energy that can do whatever he wants, ranging from offensive attacks to even defensive moves, making the Spirit Avatar one of Dragon Ball's most overpowered techniques.

Gohan Beast's Special Beam Cannon Is The Strongest One Ever
Debut Arc: Super Hero Arc
Although this legendary technique is an invention of Piccolo's, the strongest iteration of the Special Beam Cannon came from the hands of Gohan in his newly awakened Beast form. In this state, Gohan sits comfortably within the ranks of the most powerful characters in the entire story who matches Ultra Instinct Goku and Ultra Ego Vegeta.
In his many transformations throughout the series, Gohan has typically reserved a powerful variation of the Kamehameha as his most powerful attack. However, in his strongest form, Gohan makes use of his teacher's ultimate attack, delivering unparalleled piercing damage that was shown to be strong enough to kill a terrifying villain like Cell Max in a single hit. Although this may be the strongest attack from an offensive standpoint, the fact that it needs to be charged up for a very long time does bring it down a peg.

Dragon Ball Super: 8 Strongest Characters Who Would Destroy Goku in a Fair Fight
In a fair fight, there are several Dragon Ball Super characters who would absolutely destroy Goku – even now that he's mastered Ultra Instinct.

The Beerus Ball Uses Ultra Ego Vegeta's Energy Of Destruction
Debut Arc: Granolah the Survivor Arc
Once Vegeta abandoned the need to chase Goku and his Ultra Instinct form, he allowed himself to get stronger purely to shatter his own limits, which ultimately proved to be the correct decision since it forced him to awaken Ultra Ego, which is the form of the Destroyers that not only allowed him to house the Energy of Destruction, but also to surpass Goku.
In this state, he battled Granolah and was initially far stronger than him, which in itself is quite an achievement since Granolah not only one-shot Mastered Ultra Instinct Goku, but was also the strongest in the universe. By imbuing his attack with the Energy of Destruction, he made a massive ball of Ki that could destroy anything in its path, and the only reason it was overpowered was because Granolah was forced to unlock an even stronger form. Although Gohan's Special Beam Cannon would also likely overpower the Beerus Ball, it would only be able to do so after charging for long, which ultimately makes Vegeta's technique better.
