Palm Siberia

 Palm Siberia (パーム- シベリア, Pāmu Shiberia) is Knov's apprentice.

Personality
Palm is initially shown to have an erratic personality which can be often intimidating to those around her. She is also stubborn and persistent like most enhancement types. She does have a serious side which is shown when she went in an undercover mission to infiltrate the Chimera ant's king palace as a spy. She is also a good cook.

Human
On most occasions, she has scruffy hair and too much make-up, not to mention a frightening aura caused by stress. However, sometimes she will do herself up and looks stunning.

Chimera Ant
She retains her scraggly wavy hair, but it seems like her mermaid crystal ball is fused into her body and is now featured with a crystal orb over her forehead and small amounts of scales over her for-arms and lower-legs. Other than this, her physiology seems to have remained the same.

Chimera Ant arc
Palm first appears after Gon and Killua escaped from Neo Green Life (NGL). She wanted to enter NGL to follow Netero, Knov, and Morel that left a condition that she can only follow them if Gon and Killua win against Knuckle and Shoot. Palm called Biscuit to help them get stronger for the upcoming battle, there she develops a crush on Gon at one stage during his training. Palm is sent in as a personal secretary to Director Bizeff so that she can see secretly see the Chimera Ant King and track his location. However she was discovered by Neferpitou's En and broke down, just like what happened to Knov. She committed suicide but was revived in time and transformed into a chimera ant soldier by Neferpitou and Shaiapouf as the first experimental soldier for the "selection". She was saved by Killua and after that she freed herself from the Shaiapouf's control. She then went to meet Gon and sees him depart to Pejing with Neferpitou. She observed all of Gon's fight with Neferpitou and, after sending Killua to Gon, remains to protect Komugi along with Ikalgo. When the King goes in search of Komugi and senses them she hides Komugi, separates from Ikalgo, and faces the King alone. Noticing that the King is going to die by the Miniature Rose's poison and, touched by the King's love for Komugi, she let them meet for one last time. She then goes with the others to take Gon to a hospital and, once inside, she sees the King's death through her "Wink Blue" ability.

13th Hunter Chairman Election arc
After the King's death she is seen along with Ikalgo in the hospital near the Hunters Association's headquarter waiting for Gon to recover from his critical condition.

Abilities & Powers
As a human Palm was not as well trained in combat compared to the other Hunters, demonstrated by how easily Killua| outrun her. Even armed with a kitchen knife, she does not represent a threat to him. After being reborn as a Chimera Ant, Palm became physically stronger and has all the benefits that many Chimera Ants present. The psychotic nature that upset her mind in the past seems to have disappeared. She is decently skilled in hand-to-hand combat, having had a brief clash with Killua before regaining her senses and snapping out of Pitou's control.

Nen
Palm is an Enhancer, so she can use her aura to increase her natural abilities. She is also capable of leaving messages by detaching the aura from her body. After becoming a Chimera Ant she can use her previous Nen ability, although slightly different, from her human form and a new one. It is revealed by Meruem that her aura has become stronger and he commented she has “the strongest beauty of all the times I've seen, up until now”.
