The Rare Pokemon Virus You WANT To Catch! | The SCIENCE of... Pokemon (Pokerus)

SUBSCRIBE to Catch all the Theories! ►

We've talked about shiny Pokemon, one of the rarest finds in any Pokemon game. Today, Austin is going a step further in the rare department. Theorists, have any of you ever heard of the Pokemon virus known as the Pokerus? I'm going to guess even some of the most fanatic of Pokemon fans watching this have not. What is the Pokerus? What does it do? And why, Theorists, do you WANT to catch it? Austin, take it away!

    When I was younger I remember my friend coming over to show me and my other buddy his pokemon had pokerus, I was very skeptical on it even existing because it sounded like b.s.and I've been playing since gen 1. Anyways I took a look at his pokemon and I was shocked so I asked him how did he get it and where he was at that time to see if I could get it but he insisted that it was just luck and location had nothing to do with it but I went over to the same place which was victory road (ruby version) and started battling random pokemon and ended up fighting a loudred after the battle I went to the nearest pokemon center and in my disbelief the nurse said my pokemon has it!!! I was so estatic what is the likely hood that 2 people in the same room getting pokerus within an hour of each other and mind you this was back in the gba days and me and my friends didn't have a link cable so there's no way I got it from him. I asked my third friend to go to the same area I was just to see if he got it but unfortunately he wasn't so lucky .even to this day I'm still skeptical on it being a luck thing.

    Again with the Kanto Plurals. The singular and plural forms of a Pokémon's name are identical. Changing the spelling to pluralize the name was a localization error from the first few episodes of Season 1 of the anime. It was corrected in later episodes soon after it was discovered. If I've said it once, I've said it a million times: in terms of pluralization, the closest English word to a Pokémon's name would be _deer,_ as its singular and plural are identical under all circumstances. Here's an easy rule to remember when pluralizing the name of a Pokémon: _The plural of Pokémon name X is always X. No spelling changes, no pronunciation changes, no exceptions._

    Honestly, when people say they "killed" a wild Pokémon, it annoys me to no end. Pokémon are only killed in certain cutscenes of the dark story for _Pokémon Insurgence,_ a scene where the protagonist rips off the head of a Nuclear-Type (I wish I was kidding) in the fan-made _Pokémon Uranium_ fanfiction _Adventures in Tandor,_ and the incomplete and abandoned fanfiction _Game of Champions._

    I like to make my Pokémon blindingly fast. More specifically, with the Snivy line, I like to combine blistering Speed (taking advantage of its status as Unova's fastest starter) with mind-blowing Special Attack and go with moves like SolarBeam, Giga Drain, Energy Ball, and Leaf Storm, as well as getting it to hold a Miracle Seed to ramp things up even further.

    The chance of finding a shiny Pokémon was actually doubled in Gen VI. EV training is very much not as extreme as presented here. As at least one other has pointed out, it's not one-to-one; at level 100, a given stat gains one point for every _four_ EVs it has. A Pokémon can have up to 510 EVs _total_, and any given stat can have up to 252 EVs (255 prior to Gen VI) devoted to it. This means that, at level 100, you have 127 extra points, not 510, to distribute among your Pokémon's stats, with any given stat capping out at 63 extra points. Vitamins, also, are no longer capped at 100 EVs as of Gen VIII and can be used to maximize the relevant stat (provided, of course, that your Pokémon doesn't have too many EVs elsewhere). The Cofagrigus presented as a base example is impossibly weak. The numbers used are its minimum stats at level 100 (from Bulbapedia), which are calculated using zero EVs, zero IVs (the Pokémon's genetic disposition for each stat, essentially), and a hindering nature (if applicable; nature has no effect on HP). Any given nature will raise one stat by 10% and lower one stat by 10% (five natures, known as "neutral" natures, effectively raise and lower the same stat, canceling themselves out and changing nothing). Since a Pokémon can have only one nature, only one stat can be calculated with a hindering nature. A Cofagrigus with zero EVs, zero IVs, and a neutral nature would have stats more along the lines of 226 HP, 105 Attack, 295 Defense, 195 Special Attack, 215 Special Defense, and 65 Speed. The boosted Cofagrigus is also impossible, as it would need its Defense, Special Attack, and Special Defense all boosted by its nature in addition to having 252 EVs each. That Speed stat also requires at least 32 EVs.

    Ok so 1 minor detail. EV's do mostly work the way he described but not nearly as efficient. It takes 4 EV's to increase the stat by 1 and no stat can have more than I believe 252 EVs so you can only increase the stat by around 60. I know my math is slightly wrong but there is definitely no way you're increasing a stat by 500. It's 1/4 of that and has to be put into 2 stats
