Jack (Rusty Rivets)

"As always, Jack gives me a lift to stop these pesky Coalition of the Red Star forces that roam around the world... and would probably roam around Sparkton Hills as well."

--Su Ji-Hoon, Riveting Rusty

Jack is a main character in Rusty Rivets.

He is a relentlessly obedient, cube-shaped Bit who can lift and transport objects using his forklift-like arms.

In When the Cold Breeze Blows Away, he serves as a supporter of Team Rusty Rivets as a lifter and a transporter.
