Part of the fourth generation of Knightmare Frames, the RMI-13 Portman is the first (and apparently only) amphibious Knightmare to be produced. Much of its outward design is made with hydrodynamics first in mind. In addition to the standard Slash Hakens, the Portman has a set of torpedo launchers mounted in its shoulders, and a hydro jet pack mounted on its back. Though intended to operate primarily underwater, the Portman can also be used on land, though its speed and combat skills are poor in this area.

Portman II

 * Series: RMI-13
 * Height: 4.72m
 * Weight: 5975kg
 * Weapons:
 * Slash Haken × 2 (スラッシュハーケン, Surasshuhāken?)
 * Torpedo launcher × 4
 * Equipment/Installment:
 * Landspinner propulsion system
 * Cockpit Ejection system
 * Hydro Jet Pack

A upgraded version of the Portman, the Portman II appears in the second season during an attack on the Black Knights submarine. It is considerably faster than the original, and appears to be even more specialized than its predecessor, lacking fingers completely in favor of an extra pair of turbines.
