Randy Robertson is the son of Joseph Robertson.
As a teenager Randy became involved with a gang called the Bandanna Gang which was lead by Tombstone. He did this because he believed his parents did not care about him and the Bandana Gang made him feel like family.
Randy later met the Bandanna Gang's leader, Tombstone. Randy, along with the rest of the Bandanna Gang and Tombstone, broke into the Spaulding Chemical Plant. However, Tombstone was actually planning to frame Randy for their crimes.
When Robbie came to the Spaulsing Chemical Plant he confronted Tombstone. Tombstone told Robbie that Randy wasn't wearing gloves and that his fingerprints were all over the crime scene. Tombstone also told Robbie that he was recording Randy robbing Spaulding Chemical Plant and he would use it to implicate him in the robbery unless Robbie were to cancel an exposé the Daily Bugle was planning to run on his employer, Alisa Silvermane. however, Robbie told Tombstone that he was able to rush the story into print and that within a few hours everyone in New York City would know about Alisa's criminal activities. Tombstone was disappointed that he couldn't complete the job Alisa hired him to do but was satisfied knowing the Robertson family name would be ruined when everyone learned Randy was a criminal.
Spider-Man then arrived at the Spaulding Chemical Plant and found Robbie and told him that the Bandanna Gang was going to frame him. Randy didn't believe Spider-Man and said that the Bandana Gang treated him like family even more then his real family. Spider-Man then showed Randy that his father was at the Spaulding Chemical Plant risking his life by fighting Tombstone to save Randy.
After Tombstone was arrested Robbie told Randy just how much he cared for him.
