Fact: Batman would own Goku
How did I come to this conclusion? Well that is simple.
First: Superman > Goku. Here is the proof: http://static7.comicvine.com/uploads/scale_super/12/123441/2925503-break_down.png
Second: Batman > Superman. Anyone who has seen The Dark Knight Returns or Batman v Superman would know that. http://66.media.tumblr.com/eb1a90cee2d1e8fed41af68d31f10c66/tumblr_mgjwhd9got1qa69wso7_400.gif
So therefore Batman > Superman > Goku. http://images-cdn.9gag.com/photo/am9dWgV_700b.jpg
And that isn't even taking into account one very important factor: #HE IS THE GODDAMN BATMAN! https://66.media.tumblr.com/2e1db2a0c1e0682ffc741dbb8b3743bc/tumblr_nyhsrqT4U91tslewgo1_500.gif
As long as Goku doesn't say Martha, Batman can't lose. http://media.fyre.co/5X9mksdcSHCFAD7Vretr_60c108c2735d549e50fd8c7e2c6927da3de95b46220fac64932f9d26aa2d08ae_1.gif
Now, I know all you Goku fanboys will some how find a way to take offense at basic logic. You know where to find me. http://i.gifntext.com/49911-well-here-i-am.gif
