it's a series of in-depth summaries written by passionate fans but it's not canon in any way aside from their full Ask Vector Prime transcripts.@Thirteen prime @OtherGalaxy is TFWiki a reliable source? Since I see many TF scalers using it and they say the wiki has canon information in it
Is it reliable? Yes, but it should never be used over the actual stories. As one example we were talking about a week ago, they don't have Alpha Trion listed as a member of the Multiversal 13, even though he's confirmed to be one when Vector talks about Trion's higher wave form unifying all Alpha Trions. Or how they have their own complex reasons for not considering Alignment canon, even though AVP officialized it.
It's an amazing resource we're extremely lucky to have, but what its users write isn't actually canon or published by hasbro/takara at the end of the day.
