- "The Spader has arrived!"
- — Spader, after his arrival.
Spader is a Goliath tarantula, and is also the 9th member of the Rocko Squad. He is a good friend to many Tekken fighters, especially Alisa Bosconovitch.
In his premiere episodes, Alisa Bosconovitch and Sakura Kasugano mistook him as a spider but he corrected both of them. They also showed arachnophobia, which is a fear of spiders, when they first met him, though he is part of the Rocko Squad, meaning that he's a nice spider...or tarantula.
In Barney and the Rocko Squad, the appearance of Spader will also trigger the appearance of the Olsen Twins. The only episodes of this show that doesn't cause this to happen are The Rock of the Rock and A Time of Sharing.
Spader is voiced by the following voice actors:
- David Schaufele, who also voiced Bryan Fury in many Tekken games (Alisa's Adventures in Rockoland)
- Robert Sweatman, who also played Mr. Grady Boyd in Barney & Friends (Barney and the Rocko Squad)
- George C. Cole, who also voiced Ganryu in the first two Rocko Squad television shows (Xianghua in Rockoland)
- David Jeremiah, who also voiced Lei Wulong in many Tekken games (The Rocko Squad Meets Pippi)
