Vegito was produced as a result of the fusion between Vegeta and Goku which happened through Potara Earrings from the Supreme Kais. Even from the name, we can tell that Vegito is a product of both of them. Vegito shows features of both Vegeta and Goku, meaning he is a true mixture of Vegeto and Goku. Also, we see that Vegito has two hanging locks of hair.
Vegito has features of benevolence and intelligence which he got from Goku. Gogeta, on the other hand, is a product of the fusion between Vegeta and Goku which happened through fusion dance. Gogeta is slender and tall, similar to the body features of Goku. Gogeta also has Vegeta's facial features. Unlike Vegito, Gogeta only has one hanging lock of hair. Of all the characters, Hogeta is believed to be the most powerful. Gogeta also has Goku's skin, which is peach-like in color.
