Shadow Radar
The Shadow Radar was introduced on 1st July 2019 to celebrate PokéHeroes 6th anniversary, in memory of the Pokeradar, back then called the Shiny Radar. The Shadow Radar is a permanent feature.
How it works
Our local computer scientist and favorite nerd in town, Bill, has developed a new device, called the Shadow Radar 
. This item makes it possible to find these Shadow Pokémon in the wild. It is available in the Item Shop after reaching Trainerlevel 20. You can either buy it with PokéDollars or with Nuggets.
After purchasing the Shadow Radar you will be send out on a 10x10 field of tall grass. Pokémon-Shadows 
will randomly appear that have to be clicked on.
If it turns out to be a regular, non-shadow Pokémon, it will start a chain of this species and count up in your Shadow Radar. The longer your chain, the higher will be the chance to find a Shadow version of it. However, if you find a species that is different to your chain, then your chain will break and you'll lose the game.
Tip: Remember the field where you had you last Pokémon fight. The longer the distance between this field and the field of your next fight, the higher the chance of finding the same Pokémon-Species. You don't have to click on every appearing shadow. Sometimes it's better to wait a bit until it appears in a spot that is further away from the spot where you challenged the last Pokémon.
Also make sure to have enough 
Poké Balls with you! They are mainly available at the Item Shop.
Some Pokémon are harder to catch than others and take a few more times. And not to mention that there's also a slim chance of the Shadow Pokémon fleeing during the fight, so maybe also bring some 
Ultra Balls!
Details: The species that can be found in the wild vary every day for every user.
- Regular users have a set of three species available per day.
- Premium members have a set of five species available per day.
You can only catch one Shadow Pokémon per day. There are, however, upgrades available at the Item Shop (Special section) that permanently increase this limit.
Some species are rarer than others and require more experience. After catching more and more Shadow Pokémon, you will start to find rarer Pokémon out there.
Note: As soon as you find a Shadow you didn't encounter before, it will show with the text NEW beside the Shadow sprite.
Notes
Currently, only Pokémon from the Kanto region and Johto Region are available as Shadow Pokémon. In the future, more regions will be added!
Kanto region Shadow Pokémon are able to be hunted upon the purchase of the Shadow Radar. However, Johto region Shadow Pokémon can be hunted once you've purchased the Shadow Radar Upgrade (Johto). This upgrade can be bought over at the Item Shop for 
100,000.
Shadow Pokémon cannot evolve. They can not be shiny. They also cannot be hatched from Pokémon eggs.
