Fortegreen (Impostor)

Fortegreen is one of the main antagonists for the first seasons of the Alternate series, with much less influence and being more of a supporting character in the Original Series. They're a shapeshifting parasite-like impostor from Polus with the goal of killing all the crewmates on Polus. They have a strange, unexplained fascination with the device previously belonging to Purple.

## History

### Main Series

Fortegreen made their first appearance in the Main timeline during the third episode of season one. They're seen in their parasite form by Yellow, who Fortegreen then chases and tries to kill Yellow using a knife, but was stopped by Glitchy using the device to throw them. Yellow called a meeting, but Fortegreen was able to pretend to be the crewmate Fortegreen, thus getting them out of trouble.

In the next episode Fortegreen was seen trying to kill Brown while they were calling Green, but to no avail. They did, however, learn about Glitchy being an impostor. They were able to trick Glitchy into following them after finding the child alone and shifting into Yellow. After luring Glitchy into specimen, they proposed a deal with them. Fortegreen offered to work together with Glitchy to kill all the crewmates, though the offer is declined. Fortegreen begins fighting Glitchy, eventually coming out victorious.

During the final episode of the season, they are seen in lower specimen by Brown and Tan. Brown realizes that Fortegreen had been an impostor, not the crewmate Fortegreen. Fortegreen stabs and almost kills brown while keeping Tan alive. They nearly killed brown a second time before being stopped by Lime. The rest of the crewmates arrive and Fortegreen almost escapes by threatening Tan's life, but Glitchy returns and attacks them, causing Fortegreen to drop tan. Everyone begins working together to fight Fortegreen, and in the end, Fortegreen is defeated and punched into the lava below by Yellow.

### Alternate Series

Once again, Fortegreen's first appearance is in the third episode of season one. They're seen in their parasite form peeking into Red and White's room while they are both asleep (or so they thought). Red hears their footsteps outside and comes out to attack them, but Fortegreen barely escapes through a vent. They appear again at the end of the episode once again while Red is in storage, where they crawl out of a vent behind them and form into their 'crewmate' form.

In episode four, they immediately begin attacking red. They fight until Fortegreen realizes Red is an impostor, causing Fortegreen to stand down. They began talking with Red, and lied about them wanting to protect crewmates like Red did. They also claim that they'd been turned into an impostor via infection from the parasites. Red agrees to help them fit in on Polus, and Fortegreen shifts to Olive colour so they wouldn't be found as an impostor out due to them sharing a colour with someone already in the Polus crew. Everyone quickly warms up to them after they're introduced. Later in specimen with Red, Fortegreen destroys everything as them and red begin yelling at each other. Yellow (and Glitchy) walk in on this, and Fortegreen jumps up to them and tries to kill them. They chase yellow as Red stops them from killing them. Red is able to escape as well, as Fortegreen uses a parasite from specimen that rapidly grows to try and get red, but the door closes on them. Yellow calls a meeting, where Fortegreen eventually arrives and accuses yellow of being an impostor. In the end, Fortegreen ends up with one more vote than Yellow, but secretly uses Red's device to switch a vote so Yellow gets ejected instead. Fortegreen forces red to change the text to trick the remaining crewmates that yellow was the impostor to save both of them. Tan then takes Fortegreen (and Red) to medbay to treat them to the wounds they got from when Fortegreen was chasing Yellow.

The next episode on Polus starts off with Red and Fortegreen in medbay. After Tan treats all of Fortegreens injuries, they request that Red and Fortegreen scan. Fortegreen sneakily uses a small parasite (if it was from Fortegreens body or part of the parasites from specimen is unknown) to cut the wire on the scanner and getting Tan to agree to have crewmate Fortegreen fix it overnight rather than right then. Fortegreen and Red leave medbay together, where they once again begin arguing. Red eventually pins Fortegreen against a rock and threatening to kill them, before Brown, Orange and crewmate Fortegreen walk over and see it. Red tries to tell them all about Fortegreen being an impostor, but Fortegreen simply puts it off to Red's lack of sleep making them delusional. Red leaves and presumably Fortegreen too. They aren't seen for the rest of the episode, but their parasites are seen spying on Red, White and Blue at the very end.

The finale of the season starts directly where the last one left off, where the parasite spy returned to Fortegreen and told them what they saw. Fortegreen tells it to destroy the emergency meeting button as they leave and kill crewmate Fortegreen, Orange and Brown, and kidnap Tan by carrying them with them with one of their tentacles. By this point Polus has been completely overcome by parasites. Fortegreen sees Red, White and blue attempt to escape, but they see that Fortegreen has tan. A few seconds later, Pink and Purple's dropship crashes down, destroying both their ship and the one that was already on polus. Fortegreen offers to Purple that the two of them and Pink should team up and kill the others, which is met by an incredibly powerful punch. They come back very angry, but pink attacks them and they begin fighting. A few minutes into the fight, Fortegreen has an opening to throw pink into the mass of parasite near them. But that backfires and Pink comes back with tentacles (that have mouths, for some reason). Fortegreen just throws them again. They turn around to see Purple and Red, both holding their halves of the device. They approach the two of them, catching both of them off guard and picking them up with their tentacles. They're about to force the device back together until a canister of something is thrown at them. They see pink had thrown it, who then propelled gasoline all over the nearby parasites and lights them on fire. Fortegreen tells the parasites to quickly create a fog, surrounding everyone. They find glitchy in the fog and attempt to eat them whole, until Red attacks them for it, supposedly killing them. But when everyone else was about to escape onto the rescue ship that arrived, Fortegreen comes back and stabs red, causing everyone to rush on. But the ship tumbles while flying away, causing Tan to nearly fall of but be caught by Purple. Though, Fortegreen is able to send the parasites just far enough to hit Purple, thus making them drop tan, killing them. The others escape, but, with all of the Polus crew dead, Fortegreen has won.

## Relationships

They quite literally have a negative relationship with every character they've interacted with this, which ultimately makes this section pretty pointless.

## Trivia

* In Shapeshift, during the scene where Tan was treating their head injury, they were originally supposed to give Fortegreen a snow crewmate on their head instead of a band-aid.

* Rodamrix said that the scene with their parasite form in Power was fun to animate

* It was confirmed that pre-series Fortegreen would stalk the Polus crew in parasite form (like how they did in Uneasy) in order to learn how to act like a crewmate.
