To me, Penguin
is the main bad guy of the old Batman TV show.
Side
Note: I have been struggling with how to refer to the show. It has
been known colloquially as “Batman
‘66” for a few years now and I
think that can be almost 100% attributed to Chris Sims. But that’s
not the actual name of the show, so I don’t want to call it that.
But I also can’t just call it “Batman”
because that encompasses lots of things. So I guess I’m taking the
less concise route and calling it “the old Batman TV show”.
Thankfully I don’t feel the need to add in “with Adam West”
every time.
