     Code Bio: Developed from stolen Golden City technology, the Combat
Crawler X2 is a dangerous new addition to the robot army.  Its powerful legs
enable it to scale sheer mountain cliffs or city walls, and anything that it
can't climb over, it can dig under with its armor-piercing claws or blast
through with its top-mounted cannon.  In battle, the Combat Crawler becomes
twice as deadly, deploying its cockpit section as a separate battle machine
designed for high-agility ground combat while the heavily-armed carrier unit
fights autonomously, carrying captured EXO-FORCE prisoners in its armored
cell.

     Short notes: This was a Target exclusive, a big six-legged crawler onto
which plugs a $15-size (if stripped down) bipedal battle machine.  There's a
big spring-launch cannon on top of the carrier.  Think of it as a land
version of the Aero Booster, and even when I saw it for sale for $30 I passed
on it.  Certainly not willing to pay the regular $50 price tag.
     Oh, and the webpage for this thing uses both "X2" and "x2" in the name.
