Until you've beaten Ragou with the legendary beasts at the Fiore Temple, you are unable to bring Pokémon out of their natural habitat. However, certain Pokémon cannot be accessed unless you clear certain obstacles before them which require the ability of a Pokémon not residing in that area. This means there are certain Pokémon which you may only capture after the end credits roll, and some are quite hidden. The following lists those you would not have captured during missions and must go look for after the end credits roll.

Ranger No. Picture Name Location
R-003 Venusaur Venusaur is found in zone 4 of the Lila Forest. When you reach the meadow where there are Hoppips, Pikachus, Cyndaquils and Beautiflies, there is a bush towards the top that requires Cut x 1 to clear. Venusaur is found inside that little cave.
R-006 Victreebel Victreebel is found near the entrance of zone 4 of the Lila Forest, and only appears after the end credits roll. Like Weepinbell, it will gulp you down and throw you back to the entrance of zone 4 if it catches you. So, approach it from behind to challenge it.
R-009 Meganium Meganium appears in the bug forest of the Olive Jungle, and only after the end credits roll. It requires a shocking 20+ circles to capture, so using Fighting type Pokémon Assist is quite useful here.
R-021 Typhlosion Typhlosion resides in zone 3 of the Lila Forest, in a lower path near the entrance of zone 4. It is hidden behind a bush that requires Cut x 1. Beware of the Weepinbell near this bush, it may throw you back to the zone 3 entrance if you get caught up.

Once you capture Snorlax, you will be prompted to go back to Ring Town where you receive the Completion Emblem.

R-205 Regirock Regirock is one of the most tedious Pokémon to find. It lives in the Cycla Mountain Range right next to where the Vileplumes are. First of all, break the big boulder with Break x 3, then use Water x 1 to grow the plant for climbing. Afterwards, break the boulder at the entrance with Break x 3 again, then there is finally an ice block inside requiring Burn x 3. Beware that the corridor leading to the cave is inhabited by Gastly, which will swallow your team Pokémon if they get caught up in it for too long. Capture them and release them will safeguard your team members, or simply avoid them and exit the room quick.
R-206 Regice Regice is found inside the Panulla Cave, requiring a multitude of abilities to access like the other two legendary golems.

Go down the path to enter another room and head left. Towards north, you should see a fence requiring Cut x 2 to clear, and enter the cave behind. Inside the cave, there are various big boulders requiring Break x 2 to clear, but on careful look, you only need to clear 4 of them to get through.
