Gokule is seen to equally resemble both his original counterparts: Goku and Hercule. Gokule is seen to have Goku's body build with Satan's hairstyle, eyes and beard. He has Hercule's boots and his gi strongly resembles Goku's gi. In the anime and Dragon Ball Heroes cards, his gi is dark brown in color rather than orange and with an orange undershirt rather than a blue undershirt; In the manga, his model in Dragon Ball Heroes, and Budokai 2, he retains Goku's orange gi and blue undershirt. His alternate outfit in video games is a complete flip of his normal outfit: he has Goku's hair, some facial features, and Hercule's clothes.
After Goku returns to life, and teleports to Earth, he finds Gohan to be the only remaining strong fighter to fuse with. But when Goku threw the Potara earring to Gohan, Gohan missed it and when he finally found it he was absorbed by Buu. As the only two beings that were still alive are Hercule and Dende, Goku imagined what the fusion would look like and which of the two would be better. He chose Hercule, because Hercule had more fighting experience and might make Goku a little stronger. In addition, fusing with Dende would make the Dragon Balls of Earth disappear.
Just at the moment Goku said that Hercule would catch the earring and put it on his right ear, Vegeta appeared and Goku used Instant Transmission to find Vegeta and fuse, forming Vegito. This being the case, Gokule was only a hypothetical character in the anime, and is only seen as Goku's mental image of what the fusion would look like.
