Sigh, people will keep arguing forever about these things. For Asura's big black balls (yes, I said it) they could have been just TSO/TSB...
 * Not Chibaku Tensei, because no Rinnegan
 * No TBB because that stuff comes from mouth and is charged and using them for melee seems impractical
 * I don't recall any other kind of dark sphere power in the series, but I may be wrong

I don't get why people deny and are so against Hagoromo giving Asura power... the huge black orbs and avatar like thingy can't be manifestations of some own 'body power' (whatever that means) of Asura's because neither Hashirama nor Naruto, both having 'body power' of Asura/Hagoromo never displayed black orbs or avatar thingies... well, the latter did, but not because of his own 'body power' but because of Tailed Beasts and Hagoromo, so go figure.
