What are those benefits? The only potential one I have direct experience with (besides speed) is that the connector is reversible, but even that’s small-time and a flat out objective downgrade compared to the circular connectors of the 90s, which could be plugged in regardless of orientation.
Pretty good work with the design on the original spec species, the idea of adapting it into something like Normal/Poison feels sound.
Any particular reason why you used the G2 Pokédex style (and limitations)?
