As a writer for the school newspaper young Robertson was harrased by Lonnie Lincoln, eventually to become Tombstone, for writing a story exposing him as a criminal. Robbie withdrew the story and when he watched Tombstone murder someone first hand did not tell the police or anyone else out of fear of what Tombstone might do to him if he found out.

During his teens he was a boy racer known as "Rocket Robertson" who was known to regularly outrun the Police^[1]

Many years later Robertson got a job at "The Daily Bugle" first as city editor, then as editor-in-chief after J. Jonah Jameson's resignation. However he could not keep his secret forever and after Tombstone began killing people in New York Robertson confessed to the police he had been a witness to Tombstone's earlier crimes and concealed evidence. Robertson was ent to jail where he became friends with "Bruiser," his muscular cellmate. Bruiser was killed by Tombstone who was in jail due to Robbie's testimony against him. Tombstone then engineered a jailbreak and forced Robbie to participate in it. The jailbreak was interrupted by Spider-man and Robbie and Tombstone fell out of a helicopter, landing in the river. Robbie was found by a farmer, with whom he stayed until he had fully recovered. However the peace did not last long for Tombstone had also found the farm.

Finally confronting Tombstone Robbie stabbed him in the stomach with a pitchfork. Tombstone was only minorly injured and escaped. When the Hobgoblin was hired to kill Robertson Tombstone stopped him saying no one can kill Robbie but him. Tombstone is still at large. Robertson eventually retired from his postition as editor-in-chief at the Bugle and was unemployed.

Recently he has been seen back at the Daily Bugle , during the events of Civil War Jameson fired Ben Urich for beliving that Norman Osborn was out of Prison, Robertson however saw this as a chance for Urich to come up with a good story.

After the Daily Bugle was bought by Dexter Bennett, despite his distaste for Bennett's methods Robertson stayed silent hoping that either Bennett changed his ways or that Jonah bought the paper back. However, after realizing that the DB was indirectly responsible for the death of the women that were being photographed into the paper by the crazed stalker of a celebrity that the DB was trying to get dirt on for a scandal. Robertson quit having realized that the new paparazzi element would not change as Bennett didn't care about the victims as long as he makes money. Robertson later joined Ben Urich at the Front Line and now works as its Editor-in-Chief.

Sometime after the DB's destruction by Electro, Marla Jameson is able buy back the Daily Bugle shares from Bennett, and Jameson gives the money to Robertson to remake the Front Line into the new Daily Bugle.
