Crookedjaw II gives a summary of Ashfur’s character throughout the series.
Hope you enjoy reading about Ashfur’s character!
(MAJOR spoiler alert!)
Okay, so Ashfur was a very cute kit. He was a very close friend to Cloudtail when both were apprentices and was very glad to see him after Cloudtail came back from being captured by twolegs. He was also was very kind to his sister Ferncloud, and was very loyal, brave in battle, and calm under pressure. When Tigerstar killed Brindleface to use her body as a fill-in dog bait, Him and his sister volunteered to lead the dogs away and were critical parts of the plan. In the second series he fell in love with Squrrelflight (I shipped this) and stole her away from Brambleclaw for a little while. When she told him she just wanted to be friends, He couldn’t accept that, unlike Thrushpelt who accepted that Bluestar only liked him as a friend, accepted this and continued to help her as a friend. Brambleclaw was very wary of Ashfur and was plain scared of him, even (almost) voicing his fears to Lionpaw!
When Thunderclan helped Windclan fight the dogs in Dark River, Ashfur openly disagreed with his plan. Bramblestar became hostile but agreed. It was a surprise to all of us when he went completely crazy an tried to kill Jay, Holly, Lion and their (not) mother. And after Squrrelflight told him the truth threatened to spill the beans. After that, he became oddly calm and cool toward Jayfeather, Jay’s brother, and their sister. After that, he was murdered by a mysterious cat who was later revealed to be (SURPRISE) Hollyleaf! After a long quest to find the murderer, Hollyleaf reveals that she killed ashfur and runs into the tunnels where it appears she is crushed by a rock slide. She stays down in the Tunnels with Fallen Leaves for company for 5 books. All because of Ashfur making Squirrelflight reveal the truth. During Omen of the Stars, Jayfeather was shocked to see him in Starclan.
In conclusion, Ashfur was a good cat until Squrrelflight rejected him and he plunged into darkness and brooding.
