I wonder if it makes sense to tag this as Exostrider with design speculation. Exostrider was first created as a dual-purpose tag for Aemeath's humanoid mech transformation as well as the Lahai Roi Exostrider we "know" but it's also important to remember that Exostriders are a whole set of them, not just the one.

The commentary describes this image as related to Rabelle College which trains Resonators to pilot the Exostrider in Lahai Roi. In this way it could be taken as implying other Exostriders could be designed differently. It looks a bit closer to a mash-up of exoswarm though and probably intends to give replica vibes, so I can do that for now.

Almost looks like a Megazord to me like this. Or like the Gundam Sandrock.
