The Stikfas Mechana Robot and Bear is a terrific toy. The kit comes with all the parts you need to put together a mech and bear, extra pieces for customizing, and stickers. For around $10, you can find a box at
eBay and
Amazon.
These photos show how much personality the figures have, even without any fancy customizing:


(Alas, I can't remember the source for the photos.)

Benjamin Paul Capay uses paint and some sculpted extras:


I decided to turn mine into an homage to
Doktor A's mustachioed, fez-wearing,
steampunk robots.

I sculpted the fez and mustache out of green stuff. The "eyes" were made from thin cardboard, punched out with two different sized hole punchers.


I made the rivets simply by dipping a push pin into a glob of white craft glue (Elmer's) and poking it onto the robot.

And here's my robot with the tiny versions of Erick Scarecrow's Dizign and Kissaki I made awhile back.
