Keldeo's Manga Information is unknown as of writing.
Keldeo is in the Overused (OU) tier of competitive battling as a top-tier offensive threat. Due to a nice base 108 Speed, wallbreaking capabilities with its high Special Attack and STABs in Secret Sword and Hydro Pump, and ability to wear down its checks with Scald burns, Keldeo is a Pokémon that can give opposing teams lots of trouble as it puts an incredible amount of pressure on opposing teams. Keldeo is capable of beating one of stall's biggest special walls in Chansey due to having Secret Sword target its low Defense stat. Keldeo's typing and decent bulk allows it to check some very threatening Pokémon like Weavile, Tyranitar, Mega Scizor, Mega Gyarados, Bisharp, and Heatran. As a result, Keldeo is a low-risk high-reward Pokémon that can pull its weight against any matchup. Keldeo is best used as a Choice Specs attacker that can wither down checks like Latios and Tangrowth with Scald burns while having extremely powerful attacks that can hit a number of Pokémon in the tier for significant damage. It can also run a Choice Scarf set that allows for it to revenge kill certain threats like Mega Charizard X and Mega Diancie. Keldeo is also capable of running a Substitute + Calm Mind set that can act as a solid win condition and beats a number of Pokémon that are supposed to check it like Amoonguss and Alomomola. Keldeo's primary flaws are its lack of coverage options which will lead to it getting walled by a Pokémon that resist its STABs such as Mega Latias, Mega Venusaur, Starmie, and Amoonguss. Keldeo's Speed is good, but there are still a good chunk of Pokémon that are capable of outspeeding it such as Latios, Starmie, Serperior, Mega Lopunny, Mega Metagross, and Tornadus-T.
Keldeo cannot breed.
