I know people get upset, but I think in truth that there are more Bat-Jokers than Bat-Fans.
When people put up the Bat VS Galaktakus they are doing it more as a joke than a real serious discussion. People that take those debates and try to argue Bats winning simply enjoy the joke threads (the Bat-Jokers do anyway).
Then there are the real Bat-Fans who really BELIEVE Bats can take Galaktakus. To them I say, It's fiction, so ANYTHING is possible in fiction, no matter how improbable. Improbable, but possible.
For me Bats is really a joke character. I love looking at his spite threads. What amazes me most is that people will argue Bats winning against Galaktakus but Supes don't stand a chance in a fiery hell.
I just find it absurdly funny. At any rate I'll say this, I generally turn to the Bat VS (insert god-like character here) when I need a good laugh online.
