There use to be an amazing website with pixel avatars of basically every transformer. Does anyone know what happened to that site I can't find it.

 

Pixelsagas. Iirc the site's still live, and both its Paperformers and Pixelformer archives are still up, but if you need access, they're also up on TFArchive. If it's the Paperformers you have an interest in as well, most classic bots are there, but for more unorthodox ones including combiners, S-quinn2972 on Reddit had made numerous additional templates.

 

I could be really miss remembering this site but I don't think pixelformers is what I'm looking for. This site supply default avatars for other transformers sites

 

I actually found some examples but I was hoping to find the collection

 

Yeah, that is the late Jaynz' (TFVanguard/Neale Davidson) work. So yeah, Pixelsagas, or more readily accessible, the fandom section on TFArchive.

Edit: TFArchive - Transformers Fandom
