Earlier this month at TFCon LA 2024, Transformers Animated scholar Keyan Carlile played host to a very special celebratory panel that covered a wide array of deleted scenes that had been written for and cut from many episodes of Transformers Animated. Also hosting the panel were lead writer Marty Isenberg, lead toy designer Eric Siebenaler, Transformers archivist Jim Sorenson (co-author of the AllSpark Almanac books), and Optimus Prime voice actor David Kaye.
During this panel, a live presentation was given for each deleted scene discussed, in which nearly all of them had been newly animated and voice-acted specifically for this occasion, albeit with animation created by Keyan himself and most of the dialogue provided by soundalike voice actors (David Kaye and Corey Burton were the only show cast members that Keyan had been able to get back to reprise their roles for these scenes).
A complete recording of the panel was uploaded a couple weeks back:
And now, a high-quality compilation of just the deleted scenes has been uploaded.
If you just want to watch the scenes by themselves, check out the second video. But if you're interested in the creator commentary provided by Marty, Eric, and Jim, check out the first video as well.
The panel also goes into several characters that were cut from the show as well, including some that could have made it into the show's never-made fourth season.
