Once captured, it leaves behind the DNA Link item which can be used to merge the two Pokémon. The IVs and EVs are that of the Kyurem, ignoring the stats of te Reshiram/Zekrom, , but its moveset changes entirely based on its new form. As such, you can't bring moves across the different forms and you'll need to reteach the moves if you change the form

- In Pinwheel Forest, you will bump into Cheren who is looking for information on Team Plasma. He will join you while you investigate the forest
- Regigigas is found in the basement of Twist Mountain. However, it is unresponsive indicating it needs Regirock, Regice and Registeel to activate it
- Deep in the Clay Road are the Underground Ruins. These ruins are seldom seen caves which hold a massive puzzle. The first one is the focus of the Pokémon Regirock and has you have to do a puzzle that can only be known if you visit the place at Day and night. The puzzle requires you to move 6 steps down from the centerpiece and then move 9 steps right. Then select down to hit a hidden switch. This changes the ruins so Regirock becomes available.
- This unlocks a new key which can be shared over Unova Link, the Steel Key (Black 2) & Iceberg Key (White 2). These open up the possibilities of Registeel and Regice when shared through Unova Link
- In the Strangers House near Yamaji Town,you have to follow a puzzle which brings you to access the Lunar Wing. this puzzle has you go downstairs from the left then back upstairs on the right, then go upstairs and follow the way to the left.

Take this Lunar Wing to Marvelous Bridge and you can battle Cresselia.
- To get Heatran, you first need to get the Magma Stone. This stone is hidden away in one of the highermost cliffs in Route 18. Once that's obtained, take it to the Rebirth Mountain cave Bianca pointed out earlier and Heatran will arrive.

- Alder is battleable in Sangi Town. His grandson will challenge you when you beat him
- In case you were wondering, you CAN change the difficulty for yourself once you unlock it. If you go into the Unova Link feature, it's one of the options. So, once you beat the Elite Four, you can put Challenge Mode on, and have the levels increase on you, or decrease if you do so wish. You can also change between Black City & White City when you have the chance AND change the keys for the Regi when you have them.
- Following on from the capture of Regirock, you will receive a special Unova Link key. The Steel Key in Black 2 or the Iceberg Key in White 2. When you switch over to using these via the Unova Link function, you will then find that they instead have taken residence in the same place you captured Regirock.
- Typically, this would make them version exclusives with Registeel being Black 2 and Regice being White 2. However, the ability to share across Unova Link means that if your friend has the opposite game and has captured Regirock and got the new key, they can send that key to you.
- Once you have captured Regirock, Regice and Registeel, you now will be able to access the Colossal Pokémon, Regigigas. If you bring the three Pokémon with you to where Regigigas sleeps in the basement of Twist Mountain, and interact with it, it will awaken
