Some of the new additions coming to the already vast and expansive world of Pokémon with Pokémon Scarlet and Pokémon Violet have been announced already, including its two box-art Legendaries. However, there are still plenty of more Pokémon to come, including the region's Pseudo-Legendary.
As some of the mightiest and most elusive creatures around, Pseudo-Legendaries are stars in the franchise. There's usually one per region, but some Pokémon are so powerful and impressive that fans often confuse them for Pseudo-Legendaries. In reality, they might not quite meet the criteria to be Pseudos, but perhaps they should be.
Kingdra
Arriving in Generation II as a third evolution for the Horsea family, Kingdra quickly became one of Johto's best Pokémon. Thanks to its Water/Dragon-type combination, Kingdra has three resistances and only two weaknesses. Coupled with its above-average stats that result in a total of 540, Kingdra has all the makings of a Pseudo-Legendary.
Players could easily confuse this sea creature for a Pseudo. After all, the Dragon-type is exclusive to Legendaries and Pseudos, and Kingdra fits the bill for the latter. Besides, Kingdra is more viable than Johto's actual Pseudo, Tyranitar, making it a worthy candidate for the exclusive group.
Flygon
Ground and Dragon are a tricky combination. They result in two immunities and three resistances, although they are also four times weak to Ice. Still, experienced Trainers could make the potentially lethal combo work. Add a strong stat total of 520, and Flygon becomes one of the best Dragon-type Pokémon.
Hoenn is the only generation with two Pseudo-Legendaries, and Flygon could easily be one of those. Its design makes it look more Bug-type than Ground, but its secondary Dragon-type and strong stats make it a logical candidate for Pseudo status. Maybe Flygon can receive a regional form and join his fellow Dragon-types in the Pseudo rank.
Noivern
Ash has multiple great Pokémon in each region, but Noivern was one of the strongest. The dual Flying/Dragon-type has a striking design and excellent stats, elevated by its incredible 123 Speed. Its typing results in four weaknesses, including a four times vulnerability to Ice, but it's no different than other Pseudos like Dragonite and Salamence.
Noivern would be a better Pseudo-Legendary for the Kalos region than Goodra. It's more menacing, imposing, and awe-inspiring. In short, it's everything a Pseudo-Legendary should be, unlike Goodra, who looks like a goofball. It's unsurprising that players commonly mistake Noivern for a Pseudo-Legendary. It should be one.
Aggron
Steel is arguably the best type in Pokémon, capable of making any Pokémon a worthy opponent in battle. It's so powerful it can even improve the otherwise disappointing Rock-type, like in Aggron's case. The mighty dinosaur-like creature makes the best of its Steel-typing and, coupled with its great stats, becomes one of the best early Pokémon in Generation III.
Aggron looks like a Pseudo-Legendary. Large and threatening, Aggron's armor-like body makes it even more of a beast in battle. Generation VI gave it a Mega Evolution, making it even stronger than a Pseudo-Legendary, proving that Aggron has all the makings of one. No wonder many fans mistake him for a Pseudo.
Druddigon
Druddigon is a peculiar Pokémon. It has a striking design that makes it instantly memorable yet remains one of the most underrated Pokémon in the Unova region. As a pure Dragon-type, Druddigon is perhaps less viable than many other creatures, and its stats are weaker than expected considering its imposing figure.
Still, Druddigon could easily pass for a Pseudo-Legendary, at least design-wise. It looks mightier than many real Pseudos, especially Goodra and arguably Salamence. It might be hard to compete against Unova's actual Pseudo, the terrifying Hydreigon, but Druddigon would be a worthy contender.
Arcanine
One of the most iconic creations of Generation I, Arcanine is a Kanto superstar and one of the strongest Fire-type Pokémon in the franchise. It has excellent stats that favor Physical and Special Attack and Speed, making it an offensive beast in battle.
Arcanine is so impressive that many fans confuse it for a Legendary, mainly because of the anime, in which it appears on a tablet next to the Legendary Birds. If Arcanine isn't a Legendary, it should at least be the next best thing. Alas, Arcanine is neither a Legendary nor a Pseudo, despite what many eager fans might think.
Altaria
Altaria, the cloud-like Dragon-type introduced in Generation III, is arguably the cutest final evolution in its type. Its stats might be less impressive than expected, but Generation VI did it a huge favor by giving it a Mega Evolution and the secondary Fairy-type. Its Mega form also buffed its stats considerably, even if it still didn't reach Pseudo-Legendary levels.
Although it doesn't look nearly as intimidating as most other Pseudos, Altaria fits the bill on paper, and many fans have confused it for one in the past. Mega Altaria looks even more like a Pseudo, even if its cloud-like wings become too overwhelming for its tiny body.
Lucario
Lucario is arguably the most iconic Pokémon from Generation IV. Powerful, proud, and with a design that makes it an instant star, Lucario is so popular it managed to cross over to the Super Smash Bros. universe. Stat-wise, Lucario is an offensive powerhouse, thanks to its excellent Physical and Special Attack and above-average Speed.
Moreover, Lucario is a very popular Pokémon. It was the star of a Pokémon movie, and its Mega Evolution made it even more powerful. Ash also has a Lucario in the anime, further increasing the blue jackal's popularity. Considering its prominence in the franchise, it makes sense many would see it as Pseudo-Legendary. After all, if anyone can challenge Garchomp, it would be Lucario.
Duraludon
Steel and Dragon is a nearly perfect type combination, and Duraludon makes the best out of it. Introduced in Generation VIII, Duraludon has excellent Physical Defense and Special Attack. Its ideal type combo leaves it with two weaknesses, one immunity and a whopping nine resistances.
Duraludon also has a Gigantamax form, making it stand out even more among the sea of Dynamax Pokémon in the Galar region. Dragapult is a great Pokémon and a worthy addition to the Pseudo-Legendary canon, but Duraludon also fits the Pseudo bill, and many unsuspecting players might've confused it for one during their Sword & Shield playthroughs.
Haxorus
In the pantheon of great Dragon-type Pokémon, Haxorus has a place of honor. An offensive beast, Haxorus has a Physical Attack stat that would make most Legendary Pokémon quiver with fear. The rest of its stats might be somewhat underwhelming, but decent Speed means it can OHKO unsuspecting enemies before they even get the chance to react.
Haxorus looks so cool that it could easily pass for a Legendary Pokémon. However, it makes more sense as a Pseudo-Legendary. It's even the final form in a three-stage evolutionary line. If Hoenn can have two Pseudos, then Unova can too, and Haxorus deserves to join Hydreigon and take its place among the other Pseudos.
