Metal Rook is a cannon-armed humanoid robot piloted remotely by Bofoi as part of his Metal Series squad, its frame closely echoing the Metal Knight in the webcomic's Robot Invasion Arc. It opens fire through the large cannon fixed to its right arm, can hover and fly, and joins the squad Bofoi throws against Child Emperor's Super Brave Giant.
This unit is one of Bofoi's webcomic-only machines, operated from a distance and counted among the specialized Metal Series. Its humanoid frame closely echoes another of Bofoi's designs, the Metal Knight.
What sets it apart is the large cannon fixed to its right arm, along with a set of shields or wing-like appendages extending from its back.
Metal Rook fights primarily through its arm-mounted cannon, opening fire on opponents from that built-in weapon. It can also hover and fly. Bofoi is able to speak through the robot and link it with his other machines, sharing data across the group to sharpen their combat efficiency.
Bofoi is the creator and operator. When Child Emperor confronted him at his base over his suspected involvement in the robot invasion and called out the Super Brave Giant, Bofoi answered with a squad that included Metal Rook. The battle was short, ending when Genos rushed the base, charged through, and punched apart the giant robot.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
