GB

GB, originally named Thomasfan6, was a Thomas and Friends OC thought up by ExpitheCat (named after her ROBLOX name at the time) and created as a model by Joonas08Joonas. The first, less accurate model of Thomasfan6 was created by Joonas08Jonas on March 26, 2011 but about a month and a half later, the more accurate and more often used model of GB was created by Joonas08Joonas on June 8, 2011. He also has appeared in Sodor Railway Friends (2014) and Sodor Railway Friends (2021).

Design
Early versions of the character between 2011 and 2013 depicted GB (referred to as 'thomasfan6' in 2011) sharing Percy's basis while having blue paint and the number '1337' (in reference to the 'leetspeak' meme) on his side. With his appearance in Sodor Railway Friends in 2014, he was given orange stripes in the 'paper' version of his Thomas Wooden Railway model. His ROBLOX variants also depict him with a ':3' face.

In 2018, a new version of GB's TWR model was created using paint as opposed to paper in previous variants. He kept his blue paint and orange stripes, however this variant did not depict him with the '1337' number. In 2021, this TWR model was touched up in several places, giving him a red buffer beam, white running board, and cab windows, in addition to the number '24' on his side (in reference to ExpitheCat's birthday, April 24th), replacing the '1337' number. This version appeared in the reboot of Sodor Railway Friends.

Personality
GB is a fun-loving saddle tank engine who enjoys being with his friends and others. He likes to pull passenger trains and likes to be out and about doing stuff and exploring the island.

Bio in RPs
GB was commonly used by ExpitheCat in mini RPs and Sodor Railway Friends RPs. In 2011, some RPs portrayed him as saving Emily and Rosie from Bowser a few times, however not too much is remembered from his use in 2011. When ExpitheCat began getting back into Thomas and Friends in 2013 and started to participate more in Mini RPs, GB was often seen working on the railway with Joonas on a different branch line and in some cases working in the Blue Mountain Quarry with the Narrow Gauge Engines

Bio in Sodor Railway Friends (2014)
In addition to RPs, GB was one of the main characters of ExpitheCat's scrapped TWR series. In the first episode of the series, GB and the Trucks, GB is shown as a twin to Percy at first but is notoriously weaker and has trouble pulling large freight trains. One day, after pulling a freight train up the snowy mountain, he ends up getting pushed by the trucks before he can check his breaks, resulting in a major accident that sends him to the works to get better parts and a coat of blue paint. In GB Comes Home, GB is about to be sent home to the works as they begin painting GB's purple undercoat, however after they apply the undercoat (prior to his blue coat) he is sent to take the mail after Percy derails, and he discovers he is being relocated to work on the Ponyville Railway in addition to the Sodor Railway. In the unreleased episode, GB's Cranes, GB saves Joonas, an engine from the other railway, after he gets into an accident with trucks. Joonas is then bought from the other railway to assist GB on the Ponyville Railway and given a coat of blue paint. It was planned that GB would've been used as a private engine for the Mane 6 and would save Joonas after an accident on a bridge, however this didn't go forward due to the cancellation of the series.

Bio in Sodor Railway Friends (2021)
GB first appears in the second episode of Sodor Railway Friends (2021), with a different backstory compared to the 2014 counterpart. GB was sent to work on a new branch line that Sir Topham Hatt began building as a result of increased demand for the railway in certain areas. GB, however, could not keep up with all the work on his own, and Sir Topham Hatt needed another engine, initially opting for Nia. However, while dropping off surplus materials at Vicarstown, he found Joonas on a siding and pulled him back to the new branch line. Joonas would be go on to be repainted and help finish and work the branch line alongside GB and Nia.

History
In 2011, GB was thought up as "thomasfan6" by ExpitheCat as Percy's brother with a blue color. On March 26, 2011, the first Thomasfan6 model was made by Joonas08Joonas, however that wasn't too accurate due to the Percy basis used by him at the time, and on June 8, 2011 a newer version of Thomasfan6 was made that was more accurate. Over the next few months, thomasfan6 was commonly used in different NXTransit and Mini RPs, and at one point ExpitheCat made a TWR model of thomasfan6 using another model of Percy he had. However, GB wasn't used much between the rest of 2011 and early/mid 2013 due to ExpitheCat's at the time declining interest in the series.

In summer 2013, however, ExpitheCat ended up getting back into Thomas and Friends and as a result began to use her old OC. After coming up with ideas for Sodor Railway Friends, she ended up renaming her character to GB (standing for her TTTE-focused Youtube channel, Gamer Brony) due to the name "thomasfan6" obviously not being a good name for the character. GB became once again commonly used in places and RPs through the rest of 2013 and 2014. However, mid-way into 2014, Mini RPs began to die down due to "The Gang" beginning to get more into PBS games, causing GB to become unused in RPs from that point forward, and after the cancellation of Sodor Railway Friends (2014), GB's use in general began to decline, even in ExpitheCat's own places. In 2016, a newer model of GB was created due to the older ones not being able to work due to the newer physics engine, and he was seen in AlphystheLizard Studios Headquarters outside in front of the building pulling an "AlRuffey" truck and later on was seen in the model engine shop in WinCity as a model engine. Since then, there hasn't been any other use of GB due to ExpitheCat straying away from Thomas and Friends and other TV show-based OCs focusing on her own cast of characters.

 * In terms of Sodor Railway Friends (2014) lore, GB was used to deliver video games in Europe before coming to work on the Sodor railway.
 * In terms of Thomasfan6 Studios history and lore, GB at one point was used as a mascot for the company.
 * The improved version by Joonas08Joonas has been used to create characters other than GB, such as the Ghost Engine and Evilfang6.
 * In 2011, ExpitheCat made a Wooden Railway version of GB. The model was rather simple at the time and was considered an "old style" Wooden Railway model in 2014 after he decided to redesign the model with more detail, adding in orange stripes, a cab and a newer face.
 * The Wooden Railway model may have been created in the first place for ExpitheCat's original planned TWR series in 2011.
