Rhydon is a dual type Ground and Rock Pokemon introduced in Generation I. It evolves from Rhyhorn starting at level 42 and evolves into Rhyperior when traded holding a Protector. Take a look below for 28 awesome and interesting facts about Rhydon.

1. Rhydon is a large, gray, bipedal Pokemon with features similar to both dinosaurs and rhinoceroses.

2. It has narrow, red eyes and two fangs in its upper jaw.

3. On the tip of its snout is a cream-colored horn, which is smaller on a female than a male. 

4. There are several other spikes and projections on its head: on top is spike that curves forward, two triangular points resembling ears on the sides, a wide, wavy crest under each ear, and spiky ridges on each cheek.

5. It has a cream-colored abdomen divided into strips by thin divots. A rocky plate on its chest slightly overlaps its abdomen.

6. There is a row of spikes down its back, and has a long tail with thin, black stripes.

7. Rhydon is a physically powerful Pokémon. It is recorded as being able to topple buildings with a sweeping blow of its tail, and its horn is able to bore through solid rock and shatter diamonds.

8. Its armor-like hide protects it from heat and physical blows.

9. It is stated to be capable of passing unscathed through streams of magma and withstanding a direct blow from a cannonball without being harmed. However, because of this tough hide, it is insensitive. 

10. Despite its well-developed brain, it can be forgetful.

11. Rhydon lives in rough terrain.

12. According to interviews with Ken Sugimori, Rhydon was the first Pokémon ever created. This is further supported as its index number is 001 in Generation I, as well as early sketches from Capsule Monsters featuring Rhydon.

13. Ash’s Pikachu fought Blaine’s Rhydon in the anime and defeated it, despite it being a Ground-type immune to Electric attacks. Rhydon’s horn also serves as a lightning rod which negates electric attacks as of the rules for the Pokémon effect. Since then, that battle has been brought up frequently in comparisons between the games and anime and has spawned the popular (albeit misquoted) Pokémon Internet meme, “Pikachu! Aim for the horn!”

14. Since Rhydon’s index number is 001 in Generation I, a glitch Pokémon with an index number of 000 or that is greater than 152 will revert to Rhydon when its Pokédex entry is viewed.

15. Rhydon and its evolved form share their category name with Nidoqueen and Nidoking. They are all known as the Drill Pokémon.

16. Rhydon’s design appears to draw much of its inspiration from a rhinoceros and some aspects of various dinosaurs, such as ceratopsids.

17. Rhydon may be a combination of rhinoceros and don.

18. Rhy may also derive from the igneous rock called rhyolite, alluding to Rhydon’s Ground/Rock type combination.

19. Don, from the Latin dominus, may emphasize Rhydon’s being the final evolution of its line (pre-Generation IV), as it is a title akin to lord in several Romance languages; -odon, ultimately from ὀδούς, the ancient Greek word for tooth, is a suffix commonly used in dinosaur names, and so Rhydon’s name could be a reference to those prehistoric creatures as well.

20. A Rhydon appeared in Riddle Me This, under the ownership of Blaine. Blaine used Rhydon against Ash during a Gym battle. It briefly battled Charizard who then refused to battle. While normally tough against Electric attacks, Rhydon was defeated when Pikachu struck Rhydon’s horn, which acted like a lightning rod. It reappeared in a flashback in Volcanic Panic.

21. A Rhydon appeared in The Battle of the Badge, under the ownership of Giovanni. He loaned it to Jessie, James, and Meowth after he put them in charge of the Viridian Gym. It was subsequently used in their battle against Ash, where it was defeated by Pidgeotto and then Pikachu.

22. A giant Rhydon appeared in Bound For Trouble as a resident of Fairchild Island. Its size was due to there being excessive quantities of food on the island.

23. A Rhydon appeared in Right On, Rhydon!, where it was unique for its strength and its ability to know Surf. As a result, Pietra sought to catch it, but she needed a surfing Pokémon to accomplish this task. Pietra eventually caught Rhydon after rescuing it from Team Rocket.

24. A Rhydon appeared in Tag! We’re It…!, under the ownership of a Scientist. Pikachu and Chimchar battled it and a Magmar belonging to an Ace Trainer during the Hearthome City Tag Battle Competition. Rhydon had Lightning Rod, which left Pikachu’s Electric attacks useless, but Pikachu was able to defeat Rhydon with Iron Tail.

25. A Rhydon appeared in Bibarel Gnaws Best!, under the ownership of the head engineer. It was used in order to drill out rocks for the bridge, but the Drill Pokémon was quickly attacked and defeated by a Bibarel. When Bibarel was cornered, Ash’s Pikachu used Iron Tail to finish Rhydon off for good.

26. A Rhydon appeared in Meloetta and the Undersea Temple!, under the ownership of a Team Rocket Grunt. It was used alongside a Golem to capture Meloetta, but it was stopped from doing so by Ridley and his Golurk. Though the full battle wasn’t shown onscreen, Rhydon was apparently defeated by Golurk.

27. A mechanical Rhydon appeared in Island of the Giant Pokémon as a part of Pokémon Land.

28. Rhydon physically debuted in the banned episode EP035, as one of the Pokémon seen in the Safari Zone.
