"You called?"
— Barney, after coming to life.
— Evil-Man, after Alisa and Xiaoyu scream "BARNEY!"

Barney the Dinosaur, referred to Evil-Man as Purple Dinosaur, is a 200,000,000 year (two dinosaur years) old, six-foot tall, purple tyrannosaurus rex with a green tummy, who comes to life through the Call Barney button on the Rocko Control Pad.

When Barney came to life in Barney and the Backyard Gang, the kids screamed "BARNEY!" when he arrived. The same thing happened in Barney & Friends. In Barney and the Rocko Squad, the doll-to-dinosaur transformation animation is now based on the evolution animation from Pokémon Black and White Versions, and after Barney comes to life, he asks if someone called him. Following this, Alisa Bosconovitch and Ling Xiaoyu, the female Tekken: Blood Vengeance protagonists, would scream "BARNEY!", followed by Evil-Man angrily saying "Purple Dinosaur Detected".

During Barney and the Rocko Squad, Barney and the Super Readers keep track of Xiaoyu's crying.

Like in Barney & Friends, Dean Wendt is Barney's voice actor in Barney and the Rocko Squad, but only in the main footage. Pat Cashman, the man who voices Evil-Man, voices him during classic Barney & Friends (or Barney and the Backyard Gang) clips.
