Is Mega Bisharp a thing?

What about Kingambit?
Some readers may be thinking, "But I’ve seen a Kingambit, isn’t that the same as Mega Bisharp?" The answer is no. Kingambit is actually a separate evolution line that Bisharp can undergo, but it’s not a Mega Evolution.
How to evolve Kingambit
To evolve Kingambit, Bisharp needs to be holding a Leader’s Crest item and defeat three other Bisharp that also hold a Leader’s Crest. This process is quite different from the typical evolution process, where a Pokémon simply reaches a certain level or is traded.
What is Mega Evolution?
Mega Evolution is a powerful evolutionary mechanism introduced in Pokémon X and Y. It allows certain Pokémon to temporarily evolve into more powerful forms during battle. Mega Evolution requires a Mega Stone, which is a rare and specific item, and is often tied to a Pokémon’s ability to learn certain moves or have specific moves taught to them.
Can Bisharp evolve into something else?
While Bisharp doesn’t have a Mega Evolution, it can evolve into Kingambit under certain conditions. Kingambit is a more powerful and rare form of Bisharp, but it’s not the same as Mega Evolution.
In summary
To summarize, there is no Mega Bisharp. Bisharp evolves into Kingambit under specific conditions, but it does not have the ability to Mega Evolve.
