Finally, Thor, at his highest point, would defeat Hal and Flash.
Of course, he has a plethora of horrendous showings, especially lately. There is no getting around this.
Also, as I scan thread after thread, I have been seeing a growing trend that includes, not just the non-stop use of his low showings, but forum members that have been flat-out discounting, dismissing and discrediting actual, on-panel feats of Thor that have been immensely high.
These feats have been systematically SHAT upon to the point that it has now become common practice to ignore the fact that Thor has been shown to have everything from speed feats, to planetary-class strength, to time control, to access to power that seems to have no limit, except the discretion and need of Thor at the moment.
In short, Thor has been shown, literally, to be able to do whatever he feels like doing at any time and successfully combat any foe up to and possibly beyond Galactus-level.
So, although it is currently acceptable to toss into the trash almost any Thor feat, history, art, comment or narration that supports the FACT that he is the most powerful character in his tier (and possibly even one or two tiers above), everything I have stated in this post is 100% accurate. Whether it is fashionable or not.
