Pokemon Scarlet and Violet's Riddler Khu, one of the most reliable leakers within the community, recently posted about a couple of highly anticipated and incredibly strong, though unrevealed, Pokemon. In the past, Khu has leaked the Pokemon Scarlet and Violet starters, as well as other features that have been proven true. Khu's leaks should be taken with a grain of salt, but they are much more reliable than most found on the internet.
Khu has previously discussed a couple of Pokemon, like the Ghost-type Coin Pokemon. They've said that it was much more annoying to get than Spiritomb in other Pokemon games, and they've also discussed a Steel/Fairy-type Pokemon based on a hammer too. The pseudolegendary and legendary Pokemon of Scarlet and Violet will no doubt be the strongest in the games, but this Coin Pokemon and the Hammer Pokemon are shaping up to be heavy hitters too.
The Coin Pokemon is a Ghost/Steel-type players will be able to pick up on their journey, but while it's as simple as catching its pre-evo, its second stage is much harder to obtain. There are coins or the equivalent thereof scattered around the Paldea region of Pokemon Scarlet and Violet players will have to collect to evolve it. However, its evolution is considered OP by Khu, with the leaker also suggesting this Pokemon has a signature 5 PP move with a 140/150 base power with no drawbacks of any kind. It seems to be a reward for completing such a task, but in terms of competitive battling in Pokemon Scarlet and Violet, fans can expect to see plenty of this creature.
Furthermore, Khu confirmed that players will be able to catch the Hammer Fairy mon in the early game. It has three stages players will need to train it through, but the time investment will be worth it. Steel/Fairy is a powerful type combination, and this Pokemon could easily be a greater core game sweeper once captured. Past steel/fairy Pokemon have relied heavily on being gimmicky, like Klefki, but hopefully that won't be true this time around.
It's worth noting that Pokemon fans not keeping up with leaks and those that are really see this generation differently. It's wild. Pokemon Scarlet and Violet have revealed so little officially, yet for example, many fans know if Khu's record continues that Pokemon Scarlet and Violet have a total of 400 Pokemon -- less than half of the creatures available as of its release.
Pokemon Scarlet and Violet release on November 18 for Nintendo Switch.
