What does the "Show Player" button do?
 

What does it mean?

I honestly have yet to figure this out. So i too am interested in others answers.

Well when you friend them in DXD
their DXD name comes out. If you click on them
It will say example:

Guest03434564

Shark Scurvyskull

show pirate

if you click the show pirate it will take you just to
Shark Scurvyskull
then you can click show player to view shark as
Guest3434564

Good question mates!

Here's the way it works--if ye friend a pirate in-game, ye just friend that particular pirate--and only the pirate you were using to friend the pirate has that one as a friend.

HOWEVER, most people have more than one pirate.

SO, if ye go onto DXD and friend a PLAYER, when the PLAYER logs on with ANY pirate the PLAYER ID shows up. You click on the player ID and you have to choose to show THAT particular pirate.

The nice thing about it is, when you friend a player through DXD, all their pirates are now your friends--you don't have to friend each one individually. And ALL of your pirates have those players as friends.

Does that make sense?

whoah yours makes a lot more sense than mine! lol
