Okay, let's pretend that's a step down lol.. He also built an arena and was able to keep his superhuman intellect. The Hulk's main weakness was his stupidity. Retaining Banners' brain power after Tony Stark did him dirty was what made him the most effective being alive in the Marvel Universe. With that brain and that endless strength, nothing can really do much. I guarantee you he could soak up a Death Star blast, he's taken far worse.
