Let's see... I'll state the main villians (Possible spoilers)
Tigerstar
Darkstripe
Hawkfrost
Mapleshade
Thistleclaw
Those are the ones I can think of at the moment.
If you are talking about the Warriors series with the cats in the forest, then it would be Wayne McLoughlin who draws the covers and pictures for the Warriors series
Yes, Firestar is a cat in the popular book series "Warriors".
The cat on the cover of "Eclipse" in the "Warriors" series is Crowfeather, a sleek black tom with blue eyes. He is a main character in the series and part of ThunderClan.
In the warriors series, Tadpole is a tom cat. (A Boy)
That is a matter of ones own opinion, but most of the cats in the series say it's Berrynose.
there is no right answer everyone has their own opinion. (although mt fav is tawnypelt =D)
The third cat from the Warriors series is Fireheart, who later becomes Firestar. He is a key character in the series, taking on leadership roles and playing a pivotal role in the events of the books.
No cat went so insane that they died but Bluestar was kind of crazy when she was at her last life. She believed that StarClan hated ThunderClan.
any of the books from the first series..
Leaders are not allowed to have a mate in the Warriors series.
That is an opinion if you are talking about the cat in the Warriors series. Personally, I do.
There will not be a production of the Warriors book series.
