As a bounty hunter, there are times when certain vehicles simply cannot do what's needed of them. My speeders, for instance, are never around when you need them, preferring to sit where you left them.

Ethan solved this problem, by taking an Old AT-RT scout walker from the clone wars, and removing the forward chin-mounted blaster cannons.

In it's place, he build and installed EBD-01 (Or 'Ebb' as he calls him.)
Ebb, with his personality programming, has the ability to control the walkers movement, as well as having two front manipulator arms (retractable).

With heavy duty work in mind, Ebb's legs were reinforced with heavy duty variants fitted with repulsor pads, to dampen impacts and to allow Ebb to make long jumps safely. The old lightweight battery cells also were removed, replaced with a light fusion reactor.

The AT-BD is also more heavily armed. Ebb being hardwired into the systems also has access to the top-mounted Dual-Light Blaster turret, (Designed for taking down persuing infantry or light airspeeders), and twin Seinar heavy blasters, mounted on 180% degree swivels.

While Ethan can control the main cannons, this is often left to Ebb, who will work on Shooting down the target or persuers with the heavy weaponry installed.

With the ability to Call Ebb to him from anywhere within a five kilometer radius, and Ebb's top speed of 350Km/h, He provides excellent fire support and mobility in the galaxy's hyper-urban arenas.
