Here's why:
* Therian Forms are triggered by special conditions: These forms are only accessible by using a special item called the "Reveal Glass" on their regular forms. The Reveal Glass is extremely rare and can only be obtained through specific events or trades.
* Master Balls are essential: Once you have the Reveal Glass, you'll need to catch the Pokémon in its regular form. Since the Therian forms are powerful, it's highly recommended to use a Master Ball to guarantee capture.
Here's how to get them normally:
1. Find the regular forms:
* Tornadus - You can find it in the Sky Resort in Pokémon Black 2 and White 2.
* Thundurus - You can find it in the Abundant Shrine in Pokémon Black 2 and White 2.
* Landorus - You can find it in the Giant Chasm in Pokémon Black 2 and White 2.
2. Get the Reveal Glass: You can obtain the Reveal Glass through:
* Trading with someone who already has it.
* Specific events where the item is distributed (usually limited-time events).
3. Use the Reveal Glass on the Pokémon: This will trigger the Therian form transformation.
4. Catch the Therian form: This is where the Master Ball comes in handy. It's highly unlikely to catch a Therian form without one.
Alternative Options:
* Trading: You can try trading with other players who have already obtained the Therian forms.
* Breeding: Once you catch the Therian forms, you can breed them to pass down their forms to offspring.
Remember that getting these Pokémon in their Therian forms is a long and difficult process, so it's important to be patient and persistent!
