Quote: Flynn’s Log 1: “Slurp!”
Thorn is the Ultra Spider! Flynn wakes up on spider sands and immediately faces Thorn.
Thorn is not easy to defeat. She is intelligent and has one program: protect her lair! Thorn’s lair is the safe place for something vital to the digital crisis.
In Rescue Island Thorn attacks Flynn. Zana tells Flynn that she is the ultra spider, Thorn. In Thorn's Lair, she attacks Flynn. Later, they battle for a egg in her lair. She gets killed by Zana, who keeps the egg. She is mentioned in other books but never appears again.
