Lost series of Transformers fanart videos

I already made a post about this on another thread but i've decided to make a seperate thread for them because fuck it i wanna see these videos again for just the sheel nostalgia of it lol

The Original reply:

Lol i've been on a kinda old YouTube nostalgia marathon for a few weeks and one thing i noticed is that a series of Transformers fanart videos i used to watch as a wee lad has been almost been entirely fucking deleted for some reason except for one. 

I've thought about contacting the original uploader of those videos but judging by their recent uploads they've become a batshit insane fundamentalist christian conspiracy theorist so i decided not to.

For now i'm giving these Wayback Machine screenshots and the one surviving video in this series.






The surviving thumbnails i found on the Archive.

Here's some archive screenshots of the first video:

Apparently the first video survived til 2019 so i'm guessing it was deleted in around 2020
Here's an archive of the fourth video:
