The Ultimate Canon Fusion (until Gogeta became canon anyway)

 

Name: Vegeto/Vegito/Vegerot
Origin: Dragon Ball
Gender: Male
Classification: Alien/Saiya-jin (Saiyan in the English Adaptations) Fused Being
Age: A few minutes, since he was created by a fusion of Goku and Vegeta and defused when he was absorbed by Majin Buu
Powers and Abilities: Super strength, speed, durability, agility, endurance, skilled in martial arts, afterimage creation, flight, the ability to manipulate and use ki both defensively (can use his ki to enhance his natural durability and harden his skin to the extent he's able to block sword attacks from a fellow Super Saiya-jin with only his finger) and offensively (can shoot ki blasts capable of crossing thousands of kilometers and blowing up entire planets), can create flashes of light to blind his opponents, telepathy, telekinesis, energy sensing, resistant to transmutation, can create energy barriers, can transform to increase his power even further (can use his Super Saiya-jin transformations up to Super Saiya-jin Blue for a boost in all stats), the ability to teleport via his Shunkan Ido technique (can also use this technique to cross dimensions), can scream to open dimensional rifts via powerscaling (far superior to SSJ3 Gotenks and Super Buu), power that increases substantially after recovering from near fatal injuries, can hear people talking whilst he's asleep, resistance towards electricity, can move in gravity hundreds of times greater than the earth's, knows all of Goku and Vegeta's abilities and techniques | Can utilize God Ki to transform into Super Saiya-jin Blue, soul destruction resistance, resistance to existence erasure via powerscaling (superior to Super Saiya-jin Blue Evolution Vegeta who could punch away God of Destruction Toppo's Hakai)
Weaknesses: Vegito's arrogance was a mere ruse to get Buu to absorb him in order to save his friends and family, however, the fusion only lasts for one hour for non-Supreme Kai beings | The one hour fusion limit lasts a shorter amount of time than normal because of the amount of energy that Super Saiya-jin Blue takes up
Destructive Capacity: At least star level+, likely higher (immensely superior to the likes of Freeza, Buuhan, and Kid Buu) | Universe level+ (far stronger than Supreme God Zamasu, Kefla, God of Destruction Toppo, Super Saiyan Blue Evolution Vegeta, UI Omen Goku and Jiren, Future Trunks Saga Super Saiyan Blue Vegeto is easily stronger than a God of Destruction (Merged Zamasu stated that Blue Vegito had became stronger than gods)
Range: At least tens of thousands of kilometers | Universal
Speed: FTL at absolute minimum (immensely superior to everyone in the classic manga) Massively FTL+ (quadrillions of times faster than light; far faster than both Future Trunks arc Goku and Vegeta)
Durability: At least star level+, likely higher (the likes of Buuhan couldn't scratch him) | Universe level+ (took multiple powerful blows from Supreme God Zamasu and emerged only slightly worse for wear; more durable than Kefla, God of Destruction Toppo, Super Saiya-jin Blue Evolution Vegeta, UI Omen Goku and Jiren)
Lifting Strength: At least Class M+
Striking Strength: At least Class XMJ+ | Universe Class
Stamina: Incredibly high, never shown to get tired or winded
Standard Equipment: Nothing notable
Intelligence: Combined knowledge and battle experiences of Goku and Vegeta, is a tactical genius who used Buu's own abilities and personality against him several times during their single fight
Notable Attacks/Techniques:

Super Saiya-jin (Saiyan) Forms: An advanced transformation assumed by extraordinarily powerful members of the Saiya-jin race which increases his Base Battle-Power by 50 times, and this is proportioned to his physical attributes giving him a great and even increase in strength, ki power, speed, stamina and durability. However, without mastery of this form, much of this energy is wasted transforming and maintaining the transformation. The Super Saiya-jin form also has three additional branch states (which sacrifice speed for raw power) and is succeeded by two further transformations, Super Saiya-jin 2 (twice as strong as a regular Super Saiya-jin) and 3 (four times as strong as a Super Saiya-jin 2). There are also two god transformations. Participating in the Super Saiya-jin God Ritual will allow one to achieve the Super Saiya-jin God Form, which is temporary. With special training one can achieve a permanent god form called Super Saiya-jin Blue which uses god ki. Vegeto can use all of these transformations.

- Barrier: This barrier he puts around himself allowed him to be absorbed by Majin Buu without becoming comatose and increasing Buu's power. However, as soon as the barrier was lowered, he split back into Goku and Vegeta.

- Final Kamehameha: Vegeto's most powerful attack since it is a combination blend of Final Flash and The Kamehameha. Vegeto charges it like a Final Flash and fires it like the Kamehameha which almost killed Super Buu.

- Ki Sword: A blade created from pure, condensed ki around the right hand and formed into a sword-like object. It is usually roughly around twenty feet in length, and yet can be controlled to become longer or shorter, at Vegeto's will.

- All of Goku's techniques.

- All of Vegeta's techniques.

Other: Vegeto was Phenomenol's favorite character to wank, and those who still remember Phenom's "Vegeto vs. Vegeto" thread will sometimes cringe at the mere mention of Vegeto's name.

Note: A hypothetical post-ToP Vegito would be stronger than Post-ToP Gogeta.
