Which means that all of the less durable members of the House would be killed or K.O.'ed in a bare fraction of a second. That would leave Onslaught against the entire JLA team including Ion who (depending on which version we are talking about) could possibly beat Onslaught by himself.
Hmm, electrical signals do travel through the brain pretty quickly. And for people like Cassandra who have power on such a grand scale, I wouldn't doubt any of this. After all she transfered conciousness into Charles's body a mere fraction of a second before her neck was snapped. In fact, it was instantaneous. She'd be able to stop them.
