Oh jeez, this is gonna be a long answer. Well, in real life, I have four brothers (not including an older half brother and half sister, of course). My older brother actually has a fanpop account. link is my older brother.
Now, in the "My Hetalia Axis Powers - Incapacitalia Family RP" club, I've got many brothers and o sisters. Brother China, brother Korea, brother Doitsu, brother Spain, brother Australia, etc.
:u So yes, I have siblings. ._. Not as long as an answer as I thought it would be.
One half-sister, Jennicka. I think that's her name =/ She's 21 o 23 now.
A half-brother, Zvi (pronounced like Levi only with a 'Z' instead of an 'L'. That's easy to read & understand, right?) He's 8 going on 9 this year, I think.
A half-sister, Alyssa. She's 7. And she's the one I currently live with (unfortunately, sometimes :( ), and probably the only one I'll ever know in some fashion o certain form. To an extent, of course, considering I'll be gone in less than 5 months. :)
And finally, my baby half-brother. His name is John Jr., often referred to as ''Jon-Jon''. I call him 'Jex'. ^_^ It's all I could come up with at that time, folk :( In case some take notice to the fact that it really isn't that much better than 'Jon-Jon'.
He turned two in late November. :) My Scorpio Brother ^_^
Nov. 20th =D
And finally but certainly not least, 3 aborted fetuses in o at least the afterlife. :)
