Polythreat

Polythreat is the poly ship between Henry Stickmin, Charles Calvin and Ellie Rose from the Henry Stickmin fandom.

Canon
Henry first meets Charles in Infiltrating the Airship. The government wants the thief to take down the Toppat Clan. Depending on which path you chose, Henry and Charles will become close friends. In Fleeing the Complex, Henry can call the government for help and Charles will respond. He helps him and they both fly away from the Wall.

Henry meets Ellie in Fleeing the Complex. If he choses to escape with her by his side, they will accidently release everyone else. They team up to get pass the guards. With all the chaos, they try to run away, but the two leaders of the Wall attemps to stop them. In the end, Henry and Ellie both successed.

Completing the Mission
Depending on which paths you chose before launching, Charles and Ellie might be your allies. In the Thief/Allies path, Henry and Ellie can eventually join the Government after meeting Charles. This will lead to the end Pardonned Pals. In the Government/Allies route, Ellie and Charles meet and quickly become friends. Charles tells them that they need to get rid of the Toppat rocket in exchange for him to bring the two (ex-)criminals far away from the Wall. The three share interactions that lead them to deviate the rocket. Ellie tells Charles that he can call them for other missions. The end is Triple Threat.

Fanon
Polythreat, while not as popular as Stickvin and Rosemin, is quite enjoyed by the fandom. Even people who don't ship it romantically think that their dynamic is great. Since they are only two endings with those three, most of them would have like to have more interactions between them.

While they're are currently not much fanfictions on them, the ship is mentionned or alluded to in some AUs. The most notable being Ending the Cycle, in which Henry gets trapped into a timeline where glitches keep happening. So far, only Henry and Charles have been officially introduced. But Ellie appeared in a dream sequence, so it's likely she will become important later. In his first official appearence, Charles has a dream, so Ellie will probably have one too.

Even as friends, the three will be living in the same place. If the fanfics is centered around Stickvin, Ellie will act as the wingwoman. If not, she will still act as the sane one. The three, whether in actual Polythreat fanfics or not, are always there for each other. The fanfics centered around the relationship (romantic or not) are often Fluff and/or Angst.
