Known donors. The only phoenix known to have donated his feathers to make a wand was Fawkes, Albus Dumbledore's domesticated bird. He only gave two feathers. The first feather resides in Harry Potter's wand and the other resides in Tom Riddle's wand.
In 1993, he brought the Sorting Hat to Harry in the Chamber of Secrets, and defended him from Salazar Slytherin's Basilisk by pecking out its eyes. When a fang pierced Harry's arm and poisoned him with its venom, Fawkes used his tears to heal the wound, saving Harry's life.
As we know from the story, Fawkes is the phoenix of Dumbledore, and Fawkes also apparently only gave two feathers to Ollivander (or he took them, or however that works). One of those wands went to Voldemort and one went to Harry.
Phoenix. This is the rarest core type. Phoenix feathers are capable of the greatest range of magic, though they may take longer than either unicorn or dragon cores to reveal this.
It so happens that the phoenix whose tail feather is in your wand, gave another feather — just one other. It is very curious indeed that you should be destined for this wand when its brother — why, its brother gave you that scar.”
The REAL Reason Fawkes' Feather Chose Harry AND Voldemort (Very Dark) - Harry Potter Theory
Did the Phoenix feather in Harry's wand come from Fawkes?
The only phoenix known to have donated his feathers to make a wand was Fawkes, Albus Dumbledore's domesticated bird. He only gave two feathers. The first feather resides in Harry Potter's wand and the other resides in Tom Riddle's wand.
Following Dumbledore's death, Fawkes sang his Lament over the grounds of Hogwarts School of Witchcraft and Wizardry, and then left, never to be seen again. His tail feathers were the cores of the two twin wands which were held by Lord Voldemort and Harry Potter.
The rarest wand on both Pottermore and J.K. Rowling's Wizarding World is the Elder wand. The wand was made from the wood of an Elder Tree and the wand core from the feather of a Thestral's tail.
What is the rarest wand style in Harry Potter legacy?
Similarly, some fans might look to specific characters from the Harry Potter movies and books for inspiration about their choice of wand core. For instance, the phoenix feather is the rarest wand core and features in Harry and Lord Voldemort's wands.
Dumbledore knew a lot about magic, including dark magic, enough to know not to use it, especially for such a purpose as to preserve your soul or get rid of a part of it due to guilt. In the end, Harry Potter fans will believe whatever they want, but Fawkes was definitely not Dumbledore's horcrux.
Through this dialogue, Tom grew stronger and ultimately poured a little of his soul into Ginny, manipulating her to kill Hagrid's roosters and open the Chamber of Secrets.
It's likely Fawkes didn't enter Dumbledore's life until after the events of Fantastic Beasts 3. What's more, the book Fantastic Beasts: The Secrets of Dumbledore: Movie Magic confirms Fawkes is not Credence's phoenix at all.
Because once Dumbledore died, Fawkes left the castle. Dumbledore was the only thing tying him there essentially, so without him he was free to go. That's why he didn't come back to save Snape.
Although he wasn't turned into a werewolf, he did develop some wolfish tendencies such as a liking for very rare steaks. He married Fleur on 1 August 1997, although their wedding was disrupted by the arrival of Death Eaters following the fall of the Ministry of Magic.
In the next year at Hogwarts, the Hat also played a critical role in Harry's success against the Basilisk. Fawkes had brought the Sorting Hat to Harry's aid in the Chamber of Secrets. This provided him with Godric Gryffindor's Sword, which Harry used to slay Slytherin's Basilisk.
The Dark Lord's wand was 13½" long and belonged to Tom Riddle, the wizard who later became known as Lord Voldemort. The wand was made from yew with a phoenix feather core. The phoenix feather core was from Fawkes, Dumbledore's phoenix, and Harry Potter's and Tom Riddle's wands were both made from feathers from him.
The Elder Wand is the coolest wand in all of Harry Potter for many reasons. First and foremost, it is one of the three objects that make up the Deathly Hallows.
Harry Potter's wand was 11" long, made of holly, and possessed a phoenix feather core. This was described by Garrick Ollivander to be an unusual combination of wand core and wood.
Several years later, however, Hermione was forced to alter her parents' memories and give them new identities as Wendell and Monica Wilkins, to protect them from the Death Eaters. After the Second Wizarding War ended, Hermione found Mr Granger and his wife in Australia and returned their memories.
Fawkes, Dumbledore's phoenix, becomes a symbol of Harry and Dumbledore's shared loyalty, and of how Dumbledore's support of Harry inspires Harry's bravery.
