All special chassis variants (Invasion, Origins, Resistance, Loyalty, Special and all Hero variants) come with pre-defined skins that are distinct from the stock version and can switch to every other skin available for the chassis... EXCEPT the standard stock skin from the C-Bill variants.
There is no good reason for this restriction, and players may have a valid preference for the stock skin over the unique variant's (for example, I personally prefer the stock Enforcer's pattern over Ghillie's bush suit).
