You have to catch it
this Pokemon not appear in soul silver i check my pokedex and say area unknown in johto and kanto
Yes, also in heartgold, soulsilver and other versions as well.
just catch Pokemon and if you don't want them,set them free
No because in black it features Pokemon which were not discovered in soulsilver so the pokedex and game wouldn't be able to tell what Pokemon it was or if it was real. hope that was helpful! :-)
