While Andrew Hussie jokingly announced that all fantrolls are canon, the true canon fan trolls are trolls created by fans that actually appear in Homestuck. The requirement to be canonized was for their creators to donate $10,000 to the Homestuck Adventure Game Kickstarter. Two backers actually pledged to this reward tier, each paying $10,000 to the campaign, but unfortunately, since neither of them donated to the next tier up, $100,000, their fantrolls were not guaranteed to survive for more than a single panel.
They finally appeared in Hero Mode here and, as expected, lasted for exactly one panel before their entire planet was obliterated by a cherub later revealed to be the father of Caliborn and Calliope. Their names, Trollian handles, and other background information were not revealed in-comic. As the post-scratch iteration of Earth was shown to be in the same universe as them, they exist elsewhere in Universe C after the fall of Earth but before Caliborn and Calliope's birth.
As of March 26, 2015's Kickstarter Update #18 for Hiveswap, art assets depicting the two fantrolls shown by Andrew have indicated that they may appear in the game.
On January 10th, 2018, What Pumpkin announced that the grand prize winner of the Hiveswap comic contest would have their fantroll canonized as an NPC in Hiveswap.
Trivia
- As has been occasionally seen with canon trolls, especially Gamzee, the fan trolls' shirt symbols are considerably brighter than their blood colors. The hue of Nektan's symbol is 300, which matches violet blood; however, Mierfa's hue is 223, which is roughly in the middle of cobalt (210) and indigo (230) blood, with a slight leaning towards the latter (although she is stated to be a cobalt blood by her creator).
- Andrew also neglected to draw part of Mierfa's symbol; specifically, there should be two additional "arms" on the sides of the circle. If these were to be included, however, the symbol would match the sign of the constellation Perseus. Additionally, Nektan's horn lacks a small protrusion at the tip.
- On 4/14, the fantrolls' debut panel appeared on the updated Homestuck Adventure Map on the MSPA website as one of the various panels you could link directly to in the Act 6 Intermission 5 section.
- Sweet Jeff and Hella Bro cosplayed as the two of them on page 31 of the PXS comic Summerteen Romance.
- Their symbols are not included among the Hiveswap site's official extended zodiac
