Do you guys ever notice that there's a special mode for each generation after Kaguya? For example: Gen 2 (right after Kaguya) includes the Tenseigan, Six Paths Sage Mode, Rinnegan, and all the Tailed Beasts (they're technically the "children" of Kaguya through splitting chakra) - they all have the ability to manifest a Chakra Mode (Tenseigan Chakra Mode, Six Paths Sage Chakra Mode, Tailed Beast Chakra Mode etc). Gen 3 (right after Gen 2) includes the Hyuga, Moon Otsutsuki, Senju/Uzumaki, and Uchiha - they all have the ability to manifest a Chakra Structure Mode (Hyuga's Twin Lion Fist, Moon Otsutsuki's Green Orb, Uzumaki's Adamantine Chain, Uchiha's Susanoo etc). This explains why Asura didn't have Chakra Mode when using the Battle Avatar: He's Gen 3. Naruto had Chakra Mode while using Battle Avatar: He's Gen 3 with Gen 2 sealed inside. Just a theory, but makes sense to me.
