What does this mean?

[mathmagic]

I imported a duskull from Ruby and I didn't give it a nickname but in my pearl game it's called dark force. What does this mean? Is it special or something?

[Ruisu]

No idea never happened to me

[Goldenhammerhead]

[mathmagic]

woohoo I discovered something new. I will give you some stats after I'm out of that volcano

[Near]

you sure that you imported another dunskull with a nickname?

[~Mithos~]

i'm pretty sure you just chose the wrong duskull, that happened to me with my starter once, I had three blazikens =]

[mathmagic]

It show a black dot in the stats menu and I don't remember giving names to my pokémon in the ruby game but it can be that I gave him a nickname.

The black dot means it had Pokerus previously.
