DM-01 Codename-Big Brother

The second product to come out of the Dragon Mech Line is Unit-01 AKA "Big Brother." And when they say Big Brother, they mean it. The cockpit, located in the head, comfortably sits a 6' person with plenty of space for legroom, five disc cd changer and handy cup holder....k maybe not the cd changer but Big Brother earns it's name standing a head or two taller than a 10 story building.
Big Brother is also the first DMU (Dragon Mech Unit) model to be made into a mass production line.
Standard features are, Cranial horns expand to act as antenna to broadcast/pick up a multitude of signals, back mounted jet pack, additional thrusters located on the feet, retractable ankle stabilizers, and retractable toe claws & build in shield projectors. A multitude of over sized weapons may be used to arm unit-01 but is still formidable unarmed. Breakthroughs with biosynthetic computer components mean that after a single cranial surgery, pilots can simply "plug" themselves into unit-01 and begin training for combat right away with minimal need for complex tutorials for basic movement tasks.
The Overall success of Project "Big Brother" allowed ongoing studies & resources to be put to use for the top secret Project, Codename-"Koro"

EDIT: In the field this class of mecca is referred to as simply Brother, or Brother class so as to roll off the tongue more easily.
