Sidney Biggles-Jones
| This article is about the Cobra scientist. For the power plant named after her, see Sidney Biggles-Jones Memorial Solar Fusion Plant. |
- Sidney Biggles-Jones is a human from the Generation 2 portion of the Generation 1 continuity family.

Doctor Sidney Biggles-Jones is a Cobra scientist. The designer of an electromagnetic rail gun, Dr. Biggles-Jones's dedication to technology has given her uncanny bravery even in the face of seemingly insurmountable threats. She knows that science can level all playing fields; if one side is more advanced, victory for the other side is a simple matter of understanding the opponent's technology. Far from a shut-in, Dr. Biggles-Jones is in peak physical condition and knows how to carry, aim, and fire a weapon half her size.
She also wears knee-high boots, tights, and a stunning, contour-hugging one-piece under her open, flowing lab coat.

After he was injured by a rail gun (designed by Doctor Biggles-Jones) while approaching Silent Castle, Megatron made a deal with Cobra Commander. He would trade Cybertronic technology from the Ark for a new body which would incorporate the rail gun. Realignments When given her first glimpse of the wonders of the Ark, the doctor was rapturous with delight. Goin' South
However, she was not a typical Cobra member—or, indeed, truly a Cobra at all. She cared about the welfare of the recently injured operative Scarlett and concealed the fact that she knew Scarlett to be an undercover agent for G.I. Joe. In fact, she herself was a double agent, sent by some unknown force to infiltrate and undermine Cobra.
Unbeknownst to the doctor, the Commander had already betrayed her and offered her to Megatron as part of the deal. Megatron decided to extract and freeze her brain for transport to Cybertron. Scarlett, repaying Biggles-Jones for saving her life, confronted Megatron to save her. Sucker Punch

Scarlett's bold challenge allowed a squad of Autobots, led by Hot Spot, to intercept the reborn Decepticon Leader and free Biggles-Jones. The Autobots soon found that they were no match for Megatron's newly enhanced body, and the encounter eventually led to the deaths of Steeljaw, Chase, Brawn and Override. After dispensing with them, Megatron relentlessly chased the Joes, who were attempting to escape with Biggles-Jones. Having witnessed the nobility of the slain Autobots, the scientist willingly surrendered to Megatron, who reclaimed her and stowed her aboard the Ark before departing.
While on the Ark, Megatron revealed that he knew that the rail gun was infected with a computer virus designed to render it inoperable. Megatron explained that he'd transferred the virus to the technology he'd given to Cobra, making it all useless. Megatron and his prisoner blasted off for Cybertron. Final Transformations

However, Spike Witwicky had snuck onto the Ark during Megatron's battle with Cobra and combined with Fortress Maximus, his old Headmaster body, whom he had abandoned there years before. Soon after, Fortress Maximus confronted and battled Megatron, allowing his fellow stowaway, Skydive, to free Biggles-Jones. Unable to defeat Megatron in combat, Fortress Maximus decided to destroy the reactor core of the Ark and asked Spike to leave and escape with Skydive and Biggles-Jones. Spike declined and instead sacrificed himself along with Fortress Maximus, destroying the Ark for good. However, not only had Skydive escaped with Dr. Biggles-Jones, but Megatron too had escaped to plague the Autobots another day.
Skydive returned Biggles-Jones to G.I. Joe, where she was welcomed by Scarlett with a warm hug. All or Nothing!
Notes

- Dr. Sidney Biggles-Jones is introduced in G.I.Joe #135 ("Ninjas Own the Night," for seriously) as head of the "Rail Gun Project" for Amalgamated Super-Conductor Corp. in New Jersey. After she is abducted by Cobra, she and Scarlett are convinced by Cobra Commander to join their terrorist organization so that their accomplishments will not be overlooked due to their gender. Part of the "becoming a terrorist" process is apparently trading in one's sensible skirt and slippers for a leotard and boots. Labcoats are still permitted.
- Dr. Biggles-Jones' first name is only given in the G.I. Joe issues prior to the Transformers' involvement.
- In G.I. Joe #140, we learn that the Department of Defense has 'a pipeline into Cobra.' Odds are good that this was supposed to be Dr. Biggles-Jones, though we never learn for sure that this was who she was working for.
- Dr. Biggles-Jones's only other fictional appearance was in Devil's Due's post-Marvel G.I. Joe material, in non-Transformers-related issues. She was mentioned as being held in a Cobra prison and in a coma. She was later listed on a computer screen as having been killed.
