Thorn the Lop

At some point, Thorn became a member of the Crazy Kritter Freedom Fighters, under the leadership of Rob o' the Hedge. She and her teammates came to the aid of three members of the Chaotix when the trio came to Mercia looking for their missing teammates, Mighty the Armadillo and Ray the Flying Squirrel. Stumbling upon their guests locked in battle with the Mercia Dark Egg Legion, Thorn and the others joined in the fight, the Lop hitting a Legionnaire with a leaping kick after he had been warned to surrender by Friar Buck. With their foes defeated, the two groups exchanged introductions and stories, with Thorn and her teammates revealing that they had encountered Mighty and Ray. As Bow Sparrow explained-partly in song, which Thorn attempted to discourage given the concern of the Chaotix-the pair had come to Mercia, and had briefly aided the Freedom Fighters before heading off to infiltrate Snottingham Castle. By the end, all members of both groups had joined in the song except for Thorn, Munch the Rat, and an exasperated Espio, whom Thorn consoled despite her own amusement at the display.

Learning that Mighty and Ray had apparently disappeared, Thorn and her teammates feared the worst, and welcomed the support of Vector and the others in raiding the castle to rescue them and other prisoners taken by Mordred Hood. After learning about their knowledge of a secret passage into the castle, Espio questioned why they hadn't done this previously, and Thorn explained that they had lacked the numbers to eliminate Hood and rescue all of his Legionized victims. The expanded team set out, subduing the guards outside the castle and making their way in, unaware that their means of entry was known to Lord Hood.
