Giratina - Betsalel
iirc, it's Hebrew meaning "son of my sorrow". I think it fits.
Shiny Staraptor - Lucky
I can't chain for beans, and I have prolly 10 shinies, but they're always welcome. Only problem, was when I was going to catch it, it knew Whirlwind. Why couldn't I have the Gen. I engine then? But I caught it, it has pretty sweet IV's, so "Lucky" fits.
Lanturn - Nigel
When I caught it as a Chinchou, it reminded me of a certain friend of the same name whom I met in the 5th grade, but since I moved, I haven't seen him since...
Darkrai - Siegfried
I named him after my favorite fighter in the SoulCalibur series, Siegfried. I felt that Darkrai has had a bad past of nightmares, but is trying to redeem himself.
