I guess you mean where it is. It is in the tree next to exit from Daybreak ruins.(requires 1 tackle).
no regigigas does not
rasp cavern
he is in the sky
pokemon originaly came from there mother
in the cave of icicles
yes
it is in daybreakruins i think
you never use it
you go there at the start of the game
never after shaymin its giratina
to capture raikou in pokemon ranger gurdian signs you go to rasp cavern and keep going left and a monument will be there and so will raikou
in the forest past tilt city, I think?
