Thor's Clique: Oak and Thunder Club
Thor and Zeus have an exclusive two-god club. What do they do? Well, their secret club meets under an oak tree and they nerd out over their interest in meteorology.
Zeus
Zeus (a.k.a. Jupiter) is the Greek (and Roman) “sky god,” associated with lightning, thunder, and the oak tree. Sounds a lot like Thor, doesn't he? Thor may have a hammer and chariot that create lightning, but Zeus can just grab hold of a lightning bolt and chuck it to earth. Both gods are also linked to the oak tree, maybe because oaks are "more likely than other trees to be struck by lightning, and more likely to survive a strike" (source).
