This is not likely. After all, the entire series is set in Thunderclan.
Hazelpaw in Thunderclan? She didn't die. In fact, she's a warrior, Hazeltail.
thunderclan cats :|
well in the fourth apprentice no thunderclan cat died,but rippletail of riverclan did at the battle of the beavers.
The second leader of Thunderclan was Owlstar.
I hope you don't mind if I improve this a little Tigerclaw... Redtail (former ThunderClan Deputy) , Oakheart (RiverClan Deputy) , Rosetail (ThunderClan Elder) , Lionheart (ThunderClan Deputy), and Spottedleaf (ThunderClan medicine cat) die. Bluestar (ThunderClan Leader) loses her seventh life. (Hey that's me :)! ) Raggedstar (Former ShadowClan Leader) dies between Bluestar's Prophecy and Into the Wild Thanks -Bluestar
Many have, here is just a list of known ThunderClan deaths: Thunder, Owlstar, Lightningpelt, Mosskit, Spottedleaf, Lionheart, Sunstar, Pinestar, Thistleclaw, Darkstripe, Longtail, Brindleface, Molepaw, Dappletail, Speckletail, Redtail, Bluestar, Yellowfang, One-eye, Half-tail, Ashfur, Goldenfur, Featherwhisker, Whitestorm, and Goosefeather.
We do not know that, or if Brambleclaw will even be leader. He may die or Lionblaze may be chosen instead. But, if he was to be leader, many cats would approve since he has proved his loyalty to ThunderClan many times and is strong.
Onestar wanted a war with ThunderClan because he thought ThunderClan stole WindClan's kits, and he wanted them back.
Brightheart is from ThunderClan in the Warriors series by Erin Hunter. She is a warrior in ThunderClan and is known for her bright, intelligent personality despite her physical scars.
Jayfeather belongs to ThunderClan and his parents are Leafpool of ThunderClan and Crowfeather of WindClan.
Leafpool became a normal warrior in ThunderClan.
Yes, he was ThunderClan deputy to Bluestar between Redtail and Tigerstar.
