This version of Goku is far weaker than his mainstream counterpart, due to the fact that he was not training as hard due to being unaware of the impending Androids, and he is not known shown to have achieved any forms beyond the unmastered Super Saiyan because he died six months before the Red Ribbon Androids arrived and murdered all of the Z Fighters. However, it is possible that he could have trained in the Other World and achieved higher Super Saiyan transformations, as his mainstream counterpart did to achieve Super Saiyan 3.
Future Goku lives the same life as Present Goku until his return to Earth after defeating Future Frieza on Namek. In this timeline, Future Goku uses the Instant Transmission technique to return to Earth, where he successfully kills Future Frieza and Future King Cold when they arrive in August of Age 764.
Future Goku contracts a heart virus with no cure in Age 766 and dies six months before the appearance of Future Android 17 and Future Android 18; which leaves the Z Fighters without their strongest warrior. The androids kill the Z Fighters in May of Age 767, except for Future Gohan (Future Goku's only son), and Future Trunks. Future Bulma is confident that Goku would have defeated the androids, had he been given the opportunity, so she sends her son Future Trunks back in a Time Machine to solicit Goku's help and stop the Androids.
Future Goku is 29 years old when he dies, and he could not be wished back with the Dragon Balls because he died of a natural cause and had already been wished back before. Even if he was killed, he'd still be unable to be wished back.
In Shin Budokai - Another Road it is mentioned that at some point in the past, Future Goku returned to the living world for one day, presumably to fight Future Broly, as in Future Gohan's arcade mode, Future Gohan states that Future Goku once fought against Future Broly and had a hard time against him.
Cell mentions Future Goku in his retelling of how he obtained his cells, noting Future Goku's battle with Future Vegeta. Future Goku's cells were taken and integrated into Cell.

Forms and transformations
Main article: Great Ape Like his present counterpart, Future Goku was able to transform into a Great Ape as a child.
Main article: Super Saiyan
Like his present counterpart, Future Goku is able to transform into a Super Saiyan. He has never been seen in this form in the anime series due to his death, though he does use it against Future Bardock and Future Gohan in the PSP game Dragon Ball Z: Shin Budokai - Another Road.
Although he was never seen using this form, it can be greatly implied that like the present day Goku, he used this form against Frieza on Namek, since their timelines would start differentiating the moment Goku returned to Earth during Frieza and King Cold's presence.

Dragon Ball Z: Shin Budokai - Another Road
Future Goku appears in the story of the PSP game Dragon Ball Z: Shin Budokai - Another Road during Future Supreme Kai and Gohan's search for Future Gohan in the Other World: Future Goku fights against Future Bardock in a sparring match, and then he helps Gohan to find his future counterpart.
