If a monster is named with "Question" that could not be Special Summoned, "Question"’s effect disappears and the monster is neither Special Summoned nor removed from play. So the effect of "Question" disappears if the bottom monster is incorrectly named and is "Helpoemer", "Dark Ruler Ha Des", etc.
again, official rule from Netrep.net
you should really visit this site :D
I hope this helped you
Edit: Nek beated me to it.... that wouldn't gonna happen if I didn't get d/c -.-
