User blog comment:ImperiexSeed/STOP, only put what is confirmed, leave out speculation on these articles (and all articles)/@comment-26982641-20151021185204

For example Zachariah was never mentioned as a Seraph in tv show, but confirmed by the producers etc.

1-Leviathan vs Archangel is a mystery situation at the moment. We can assume Archangels are older nor not. From my point of view, Archangels can beat Leaviathan but its something that isn't explained yet.

2-Eve knows how angels work as she said in Mommy's Dearest. That doesn't mean Archangels but still unexplained mystery.

3-I definetly disagree. His powers' source are coming from Lucifer. Yes, Cas said that this children will become powerful and will be able defeat the host of heaven. Cas might be wrong though. As we see, he had less invulnerabilities.

4-I agree with that because he entirely became something else.

5-We cannot know about this. I think it depends on the age. For example Death and God are nearly at same age, War might be came into existince after the war between Darkness and God and Archangels, Famine, came into existince after the creation of Mark of Cain or Lucifer's corruption. Well Pestilence might came into existince with mortals. This is a complex topic. Even if I was right, Pestilence effected a fallen regular angel. We don't know if he could affect a full powered regular angel.

6-Its possibly.
