Method: In the Twist Mountain Cave, there is a man who will give you a fossil once a day after you have obtained the National Pokédex. These fossils are the fossils of the Kanto, Hoenn & Sinnoh Pokémon and you can get one at random each day so you have an unlimited supply of these Fossils. Go to the Nacrene City museum in order to revive them
Method: The next gift Pokémon is more of a purchase. In a style similar to the salesman in Kanto's Route 3, on the Marvelous Bridge, you will find a man who will sell you a rare Pokémon for 500 PokéDollars. Unlike in Red & Blue however, the Pokémon he sells you is rare and can't be obtained anywhere else in Unova. It is Magikarp.
Method: The next gift Pokémon is in a house in Route 18. When you enter this house, talk to the guy in the red suit and hat. He will offer to give you a Pokémon Egg. If you accept and hatch the egg, you'll discover that
Method: The next gift Pokémon are the fossil Pokémon. In the Relic Castle, you'll get given a choice of two fossils, the Cover Fossil or the Plume Fossil. Take the fossil you choose to Nacrene City's museum and speak to one of the clerks at the entrance. She will take your fossil and revive it into the following Pokémon
Method: The next gift Pokémon is the Illusion capable Pokémon, Zorua. To get Zorua, you will need to have first transferred Celebi over to Black & White using the Transfer Machine. Once done, take Celebi to one of the buildings in Castelia City where you['ll see a girl with another girl who is apparently lost. Celebi will come out from its Pokéball and the lost girl will shed her illusion and turn out to be Zorua. Zorua will be offered to join you. However, you do need a Pokéball as one will be used up when you obtain it. It can be any ball.
Method: The first Pokémon of which you will receive as a gift will be one of three Pokémon. When you first enter The Dreamyard, you will find a lady who will gladly give you one of the apes. The Pokémon that you receive is, however, not up to you. Instead, you get the Pokémon of the type that is weak against your starter. If you chose Snivy, you'll get Panpour. If you chose Tepig, you'd get Pansage and if you chose Oshawott, you'd get Pansear. They are at Level 10 and are quite handy for use in the first gym battle.
Method: After you have all eight badges and head to Route 10, you'll be informed of a weird weather pattern in Route 7. Head there and continue on until you reach the second house. After being invited into a house, when you leave, you'll get confronted by Tornadus and he'll fly off. From this point, he will start roaming the areas of Unova. In the mornings, he will appear in the southern routes and in the evenings he'll appear in the northern routes. He appears in Pokémon White.

Method: North of Route 13, you'll find a new area called the Giant Chasm. When you enter, this area is filled with forestry, but when you come near the lake in the middle, you'll hear a screech and the whole area flash freezes. Go to the north and you'll find the Dragon/Ice Pokémon Kyurem in a cave
Method: Once you have captured and traded with a friend to get both Tornadus and Thundurus, take them both to the Abundant Shrine off Route 14. At this shrine, when you go and interact with it with the two Pokémon in your team, the Ground/Flying Landorus will swoop down and battle you.
