I believe this plant may be misidentified and is actually a hybrid called 'Donnie' (among other names).
@Djinnrickey has proposed moving this image to the other entry.
Aloe Retro Gang™ Donnie
I will be moving that request along, but I wanted to leave a note here so that
@tabbycat is aware of the change, and so that anyone who might disagree can speak up.
Note that Donnie looks very different (in shape but especially in color) when exposed to strong light... the most obvious differences between this image and most of the ones in the listing for Donnie would relate to exposure, in my view.
