Hum...yeah forgot about that retcon. Actually they were humans who were placed under the IT, trapped in the Divine Tree, drained of their chakra and remade as living husks/puppets of the tree, hence their minor use of Wood Release and near identical DNA to that of Hashirama.

Regardless their properties are still those that i mentioned and Obito, being remade using that raw material shares similar traits to the WZ army, which would explain the lack of backlash from his MS.
