I believe it'd be more accurate to call Gore and Basarios Preadults since while they're technically the juvenile forms of Shagaru and Gravios respectively, they are themselves are too mature to be the "Juvenile" stage of this game's life cycle path though Basarios could be between Subadult-Preadult.

Remember that in 4U we saw a Gore undergo Ecdysis, becoming Shagaru in the process, meaning that the Gore in question was likely at the verge of becoming an Adult.
