Dragon Ball GT: Frieza Strikes

I personally suppose this is in the GT timeline. This is for everyone who wonders who protects Earth after everyone dies of old age, and who Trunks's son could, or would be, this is the answer. [My personal, canon-following answer]&nbsp

Chapter One, Odd Soldiers
''Pinkau sits quietly, looking into the sky. Earth was safe at the moment. He had just fought off this odd Soldier his father, Trunks, once told him about. He said he was apart of the "Ginyu Force." Recoome. He sensed another odd powerlevel. More than before. Much more. He flicked into Super Saiyan and blasted off in seconds. He arrived minuted later, to find this purpleish figure with black horns. Captain Ginyu of the Ginyu Force.''
