You can try looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. There are often many different Thunderbirds fanfictions on these platforms, and you can search specifically for ones involving Virgil getting hurt.
One common theme could be the other characters' reactions to Virgil being hurt. For example, how his brothers might step up to support him or take on his responsibilities. Another theme might be Virgil's own struggle to recover and get back to his duties.
One idea could be that Virgil is kidnapped by an old enemy of the Tracy family who wants to use him as bait to get to International Rescue's secrets. Another could be that he's abducted by a group who mistake him for someone else with valuable knowledge. Maybe a mad scientist kidnaps him to force him to help with a dangerous experiment.
His family would be extremely worried. Scott, as the eldest, would likely take charge immediately. He'd be focused on getting Virgil the best medical care possible and coordinating with the rest of the team to ensure his safety.
Maybe Virgil's injury affects his ability to perform his normal duties in future missions. This could lead to some self - doubt and a struggle to regain his confidence. The other characters would then have to support him both physically and emotionally, like Scott giving him pep talks and helping with his physical therapy.
The motive could be ransom. The kidnappers might know that the Tracy family is wealthy and figure they can get a large sum of money for Virgil's safe return.
