You are missing a few Pokemon even after beating the elite four in pretty much any case you are missing Pokemon I suggest that you go back over the region and beat any remaing trainers
After you have beaten the elite four and get the national pokedex you go to route 214.
Congratulations! You've almost beaten Pokemon HeartGold! You now have to complete the National Pokedex.
You need to get the national pokedex, which means that you need to see the 150 Pokemon in the Sinnoh pokedex.
This is an upgraded version of the pokedex you will get this after becoming pokmeon champion as long as you recorded 60 species of Pokemon in the pokedex.
You have to defeat the elite four also. Then go back to Prof. Oak, and he will give you the national pokedex. Hope that helped....

u have to get national pokedex
hes or she s on route 2209 and 214 but you have to have the national pokedex and have beaten the elite four
First, you must have beaten the Elite 4 and have obtained the National Pokedex. Then, insert FireRed into your DS and you will find Elekid at Route 205 or Valley Windworks.
To get the National Pokedex, you must have seen all Pokemon from the regional Sinnoh Pokedex after beating the Elite Four and Champion. After doing that, go to Sandgem Town and talk to Professor Rowan in his lab and you will get the National Pokedex.
Beat to elite four and receive the national pokedex (to receive the national pokedex your must at least see all of the Pokemon in the sinnoh pokedex that you have already).
