Reptilicus-G is an unused form in Gandrayda's battle in Metroid Prime 3: Corruption. Apparently she gained a cloaking shield in this form, but could be seen with the X-Ray Visor. This design was probably replaced with Gandrayda making herself invisible, instead of changing forms to do so.
Gandrayda was not known to have encountered this species prior to her fight with Samus, so this may have presented confusion for players.
"Morphology: Reptilicus-G. Personal cloaking field now enabled. Detectable with an advanced visor."
