Shapeshifter is the male NightWing "mask"/enchantment created by Chameleon first appearing in Moon Rising's epilogue. This form has scales strong enough to withstand frostbreath, as well as firescales, and the strength of ten dragons. He is said to be Chameleon's favorite form, probably because of his power and super strength. During this cameo, Chameleon under the disguise of Shapeshifter, was in possession of Darkstalker's Talisman, an animus-touched scroll. It was implied that he was working for- or at the very least provide some form of aid to- Scarlet, her premature death in Escaping Peril. Though his motives aren't immediately apparent, over the course of the second arc it is gradually revealed that he was performing enchantments for the former SkyWing queen for exuberant sums of treasure and the safety of his morphologic abilities. It is later revealed that he isn't a true NightWing, but one of the forms of Chameleon.
He was seen in the epilogue, annoying Scarlet by tapping a scroll, most likely Darkstalker's Talisman on stone, which causes her to yell at him.
During the prologue, the "Pyrite-mask" was put on Hailstorm, Winter's brother. The necklace was put on by a dragon who has previously been wearing it. This dragon may have been Shapeshifter (most likely) or one of the other masks.
When Moon, Winter, and Qibli were spying on them, Scarlet was heard yelling at him. He then flies off to grab Pyrite for her. The companion goes to the group, and immediately attacks Kinkajou, throwing her into a tree, and injuring her badly. Moon attacked him in retaliation, breathing fire on his face. Then, Winter used his frost breath, as well. Between Moon's fire and Winter's frost breath, he was blinded. During the fight, Winter noticed he was wearing "a mess of dark jewelry", which felt like iron boxes on chains. This is because of Darkstalker's scroll.
Later, after Mayfly, a doctor in Possibility, examines Kinkajou, she asks what "really" happened. Moon tells her that the RainWing had been thrown into a tree by a dragon, to which Mayfly mutters, "With superdragon strength?" This shows he may have extraordinary power, perhaps wished upon himself by Darkstalker's talisman, which he possesses.
Peril notices a large NightWing while she is traveling with Turtle and later spots his talonprints near where they're standing, noticing that he has been watching her sleep. She finds out that he is actually Chameleon, the dragon the RainWing healers mentioned couldn't sleep (for more than an hour at a time) or change color, as well as being Peril's father. Chameleon can also become Soar the SkyWing and Cirrus the IceWing. He is forced to give up the scroll at the end of the book when Peril and her friends using his Shapeshifter morph.
"Oh, this? Don't you worry. This is nothing." - to Queen Scarlet about Darkstalker's talisman.
"My talents have been proven helpful to you."
"That scroll is mine! I'll find you! I'll take it back! You'll be sorry! It's mine, it's mine, it's mine!" - yelling at Peril and the Jade Winglet as they fly off with Darkstalker's talisman.
- Shapeshifter's name suits him since it's Chameleon in disguise. Peril comments on this, calling it "a bit on the nose".
- He is noted for being the dragon appearing in the epilogue of Moon Rising, along with Ex-Queen Scarlet.
- Shapeshifter is the one of the four revealed masks that Chameleon owns, the others being Soar the SkyWing, Cirrus the IceWing, and Bog the MudWing.
