A bunch of old-gen Pokémon are in it

In today’s trailer, you can see a trainer trade Larvitar, previously known to be in the game, with another trainer’s Bagon, previously unconfirmed. (This is big news for me, specifically. Bagon is the first-form stage of Salamence, arguably one of the most powerful dragon-type Pokémon and a cornerstone of my team lineups since it was introduced in Ruby and Sapphire versions.) Another frame showed Gengar, also previously unconfirmed. The presence of Gengar presumably means its lower-stage evolutions, Haunter and Ghastly, are in the game too. Here’s hoping Scarlet and Violet doesn’t pull the same BS that Sword and Shield did with Slowpoke’s evolution chain!
