Margulis' E.S. is quite similar to Pellegri's E.S. Issachar; a very dark black and orange mech that carries a giant-sized sword with two floating wing-like attachments similar to Issachar's Crescens Claw. These attachments also function as a logical drive. It was originally designed as a multi-role unit, but because its pilot prefers melee combat above everything else, it has been stripped of most of its longer-ranged weapons. It is instead equipped with a long sword for close-range combat and kunai like objects which are thrown from the arms of the unit.
It was designed to be a versatile unit capable of waging battle at both short and long ranges, but all long-range weaponry was removed at Margulis's request; instead it was equipped with a long sword. It has also been equipped with two intimidation weapons: a throwing weapon similar to a kunai, and a small throwable high explosive.
The large, unfolding logical drive can also be used as a claw for hand-to-hand combat.
