You did'NT really specify whether you need this amount of seen Pokemon to complete the pokedex or you think that is the amount of Pokemon you have to see to complete it.
And plus i cant tell you how to see all of these Pokemon it would take forever.
if you meanpokemon 156 from the pokedex, im pretty sure its a johto starter so to get one of those on d/p/pl/ you will need to complete the pokedex on emerald and choose the Pokemon, and if im right it is totodile or cyndaquil, although i think its totodile more.
To find pokemon 156 you need to breed pokemon 155, 156 or 157 to get it or trade the pokemon from someone else. You could also pal park the pokemon from one of the previous games.
