Henshaw stomps. Eradicator was operating at Herald levels and stalemating/beating Superman. He then loss that power, hell, all of his power and was feeding on Krypto. Superman then snatched krypto out of his body. With that said, we have no idea on how powerful Eradicator is. He could be a low Herald type of guy or hell, he could be low to mid meta. He has done nothing after his battle with Supes. All speculation at this point.
