Starting May 22nd, Greninja of all 6 variants will be able to change it's form to the previously unreleased Greninja (Ash). You will need a very strong trainer to Pokémon bond to get your Greninja to change it's form though.
Form Change Requirements:
Level 4 Happiness
Your OT Greninja
May 22nd 00:00 - May 29th 00:00 BST

There is a formula for it, but it's not public knowledge.
Here's what I have found out by playing multiple seasons.

The higher the EXP you earn in a battle, the more Seasonal points you get.
If you have not yet caught a Pokémon during that Season, you'll get more points from catching it than if you have already caught that same Pokémon.
The rarer the Pokémon you catch, the higher the points you get from them.

The Poké Ball item likely looks orange due to the light that's meant to be on it in the artwork. Light makes red look more orange.
A red Poké Ball does exist on Pokémon Vortex. When a page is loading, you can see a spinning Poké Ball with a clear red colour.

The exact spawn rates are not known.
We know Legendary Pokémon are less common than Rare encounters.
UBs are the most rare.
That's all we know.

I made a Happiness tutorial video a while ago, explaining what the stat is and how I believe you can best train for it.
 

If an auction has a bid on it, you cannot remove the Pokémon from Pokébay.
Would it be possible, it'd be unfair to the person that bid on your Pokémon.

Outside of what's in the rules, and using common sense, that together should be about all reasons.
Don't spam, don't flame, don't be racist/sexist etc.
A lot of this will be in the rules. Others should be common sense.

In the last month, these were the prices for Metallic Bagon on Pokébay:
Highest price sold: 150,000
Average price sold: 58,000
Lowest price sold: 25,000
Rarity: There are currently 4,411 in the game.

Any outside help with playing the game is illlegal. An auto-clicker is such a thing that is illegal.
The fastest way to gain EXP on a single Pokémon is using a Pokémon against a training account. This is especially useful for a Pokémon with an immunity.
A Pidgeot can be used against TrainingYveltal, a Furret can be used against TypeNormal, and a Numel can be used against TrainingGroudon.
These are just some examples.

There is a formula for it, but it's not public knowledge.
Here's what I have found out by playing multiple seasons.

The higher the EXP you earn in a battle, the more Seasonal points you get.
If you have not yet caught a Pokémon during that Season, you'll get more points from catching it than if you have already caught that same Pokémon.
The rarer the Pokémon you catch, the higher the points you get from them.

You only get the VC if you're in the Top 100 at the end of a Season.
A season takes a month long. So the current Season ends at the end of May.
If you're in the Top 100 at that point, THEN will you earn the VC.

If you're in a battle, it's impossible to get a Beast Ball now and use it.
You'd have to exit the battle to obtain a Beast Ball in any way, meaning you've lost the Necrozma by that point.

Pokémon have different requirements for evolution.
Some have a specific minimum Level that needs to be reached, some have a specific item that's needed, and others will have other requirements.
You can view a Pokémon's information by clicking on their name. If it's one of your Pokémon, it should open a window on the left that includes the evolution requirement at the bottom of it. Once that requirement has been reached (for example having a Bulbasaur at at least level 16), then you can go to 'View my Team' or 'View All Pokémon', find the Pokémon you want to evolve, and then click the + button under the Pokémon's image. That lets you evolve the Pokémon.

Each Pokémon has default moves it comes with. An evolution's default moves are usually more useful than the pre-evolution. So when you evolve it's usually recommended to check the 'Use Evolution's moves' box on the evolution screen.

As with any other moves Rayquaza learns, you can select the attack as a new one you want to 'buy'.
When on your team screen (or View All Pokémon if it's not on your team), the lightning icon lets you teach new moves to a Pokémon, including Dragon Ascent to Rayquaza.

I don't consider that a broken attack. It's a powerful move, gets STAB from Staraptor, with added damage because Staraptor is Dark as well.
There's stronger moves out there that can deal just over 400 damage when used by a Dark Pokémon of its type, such as Fling and Leaf Storm.
The main Pokémon game can have one-shots too. It's not a new thing. Brave Bird is a strong move, so it makes sense it deals lots of damage.

There are quality options in the top-right when you're on the live maps.
Lowering the quality is likely to help.
Whether it'll fix the issue I don't know, but it should help.

You can battle during day or nighttime, you can choose that yourself.
You can battle on the maps, against Gyms, or against any member.
As long as the evolution happens at night, it doesn't matter when the battles take place.

There's two main ways I like to use.
The first is training Level 6 Pokémon with immunities against their respective training accounts. This gives you a lot of money per battle.
The other way is Sidequests. It takes some time, but you get over a million PokéDollars everytime you complete a region, which makes it worth it. There's other rewards in it too.

This is not correct.

A Master Ball has a 100% catch rate on every Pokémon that is NOT an Ultra Beast. A Master Ball never works on an Ultra Beast.
To catch an Ultra Beast you must use a Beast Ball. The Beast Ball has a 100% catch rate on Ultra Beasts, while not working on any other Pokémon.
A Vortex Ball works on both Ultra Beasts and other Pokémon.
As Vortex Balls are really hard to obtain, you will most likely be using Beast Balls to catch Ultra Beasts.

Again, Master Balls do not work on Ultra Beasts. If you try to use one you will waste it. Use Beast Balls for Ultra Beasts.

Normally the max health of a Pokémon is 400. This happens at level 100. To reach level 100 you need 50,000 total EXP on a Pokémon to reach level 100.
However, Shiny Pokémon have 25% additional HP, giving them a total of 500 HP at level 100.

Some Sidequest opponents can be higher in HP than 400 without being shiny, due to being of a higher level than 100. That's just for those special battles. Players cannot go above Level 100.

If a Pokémon is resisted, there's a 0.5x multiplier.
If a Pokémon is Metallic, there's a 0.75x multiplier.
Together they are a 0.375x multipler.

A weakness is a 2x multiplier.
Together with the Metallic multiplier, that makes a Metallic but weak Pokémon take 1.5x damage from a standard super effective hit.

Generally this is related to a different trade that's going on.
It's impossible to give someone money. So instead someone would put an item with a low value on Pokébay, such as a Pokéball. The person that has to or wants to give the money then bids a very large amount on that item.
As that item is not worth a lot, it's extremely unlikely anyone will outbid them. That makes this a prettry safe way to 'transfer' money.
It's not a full transfer though, as 10% of the amount used for the bid does not go to the seller. They get 90%.

Zapdos is in the Abandoned Power Plant, on the bottom floor.
Mewtwo is in Fungal Cavern's middle room, on land.

Here is a page you can use to find all Pokémon locations: https://docs.google.com/spreadsheets/d/1ev0vfL99DmaBI9vrFZ9G37v4qBAgsTEnBkTw2oboCL0/edit#gid=840249663

There is no Route 26 on Pokémon Vortex.
Route 25 is the highest numbered Route that we have on the game.

You cannot increase encounter rates.

The rarer the Pokémon, the higher level the wild Pokémon is.

The only 'increased chance', if you want to call it that, happens between having no Gym Leaders beaten and beating all of a region's Gym Leaders.
You need to beat a region's Gym Leaders to unlock Legendary Pokémon of that region (and in the case of Alola, Ultra Beasts as well).
If you are in an area where you haven't unlocked the Legendary Pokémon (for example Entei), then beating all Johto Gyms changes the chance from 0% to the standard Legendary encounter rate for that area.

There is no known way to increase chances beyond that. All rarities have their own spawn rate, which cannot be changed by the players.
