A new Rescue Bots Feature Bots toy has been found in America, at a Target - Bumblebee.
The Feature Bots are about 50% larger than the Rescan range, and transform. It was introduced in 2019, and so far there have only been six toys (including this Bumblebee).
Since it doesn't have the new Classic Heroes packaging, this must have been planned for release last year, and ended up being delayed. It was a surprise to suddenly show up, as previous waves have been listed on Entertainment Earth, and this one wasn't there (they still only have the first four waves listed).
