Birchtree is an evil, sleek, broad-shouldered, muscular, long-legged, slender, short-haired, cold, mischievous, mean, cunning, tricky, menacing, taunting, light brown tabby tom with one white paw, paler ears and underbelly, most of his tail missing from fighting, multiple battle scars crisscrossing his sleek, short pelt, long, sharp, barbed claws, and pale, cold, hateful, frightening, intense, frosty amber eyes that seem to suck all of the warmth away from cats.
He has the power to become invisible (and is also silent when invisible), to feel no pain (he's only left with scars, not pain, from battle), and to pass through solid objects if he wishes.
Brich is born to Flowerwish, a former DuskClan cat and a rogue, and an unnamed loner on the night of a lunar eclipse. He had three siblings: Mist, Pure, and Rye. Due to being born under a lunar eclipse, Mist and Birch became pure evil, while Pure and Rye became pure-hearted. All four of them gained powers.
Due to Flowerwish dying of blood loss, he and his siblings are later found by Copperpaw and Graypaw of DarknessClan. They are adopted by an unnamed queen and are given the Clan names Birchkit, Mistkit, Purekit, and Ryekit.
He is apprenticed to Rockfall.
He receives his warrior name: Birchtree.
He is later seen trapping Flarepaw in her dreams with Mistfang. Peachfur, Dawnpoppy, and Bramblethorn all travel to the Dark Forest to try and save Flarepaw. He is shown leading Bramblethorn to the Dark Forest with Mistfang after Peachfur kills Bramblethorn to save Flarepaw.
He later watches Mistfang kill a loner, Sorceress, in a dream.
He becomes Sorceress's mate, and she has his two kits: Mystickit and Morningkit.
He is killed again by his kits, Mysticdawn and Morningfire, in the Darkfire battle.
He later returns to the prophecy cats with Mistfang.
He tries to sneak up on Cottonkit, thinking that he's weak and unable to protect himself. Much to his suprise, however, Cottonkit grows to warrior size and attacks Birchtree with Tigerflower of TimeClan's help.
Like his sister, Mistfang, he has a cold, mischievous, evil personality. He is quite cunning and tricky.
Fighting is his favorite hobby.
