These are all the HQ models I currently have for my Lions Rampant.
Lions Rampant Officers of Note
Chapter Master Acro DeLuciano is Lord Elysee, Master of the Lions Rampant. He has served for nearly six centuries and is entrusted with some of the Chapter's most revered artifacts of war. He fights with The Lion's Claws, a set of masterwork lightning claws. He has served as an adept of the Ministorum (a Chaplain) and wears a rosarius (though it has no in-game effect.) His ancient suit of terminator armour is cloaked with the finest pelt of an Elyseean lion (counts as an Adamantine Mantle).
Brother-Captain Drako is master of the First Company, and is one of the most stalwart warriors of the Chapter. He is armed with dual lightning claws of masterwork quality, and has rosarius soul armour denoting his service as a Chaplain (with no in-game effect.) Like Master DeLuciano, Drako wears a cloak of lion pelt, a sign of his stubbornness and refusal to back down from a fight (count as an Adamantine Mantle.)
Brother-Captain Porthos serves as the Captain of the Second. He is armed with the ritual weapons of the office of Master of the Watch-- a broad-bladed power axe and an oversized storm shield. He also goes to battle with frag and krak grenades. He has served as a Chaplain, as is the custom of the Lions Rampant, and wears a rosarius (with no in-game effect), and an Iron Halo as his badge of office of Captain. Porthos has earned the Crux Terminatus.
Brother-Captain Valentinian is the Captain of the Third. He is armed with the ritual weapons of the office of Master of the Armoury-- a power fist and masterwork power sword. He goes to war with frag and krak grenades, and, much like his fellow officers, wears a rosarius to denote his service as a Chaplain (again, with no in-game effect.) He displays an Iron Halo in recognition of his current office of Captain, and has won the Crux Terminatus.
Brother-Captain Tartanus is Master of the Fleet and Captain of the Fourth. He goes to war with the ritual weapons of his office, a masterwork thunder hammer, frag and krak grenades, and a finely-crafted bolt pistol. Like all officers of the Lions Rampant, Tartanus has served as a Chaplain, and wears rosarius soul armour. He displays an Iron Halo as his badge of office, and proudly shows the Crux Terminatus on his right shoulder.
Brother-Captain Athos d'Elysee serves as the Captain of the Fifth. He is armed with a masterwork power sword, a plasma pistol, frag grenades and krak grenades. He has earned the Crux Terminatus and wears an Iron Halo as his badge of office. As an officer of the Lions Rampant Chapter, Athos has been ordained a priest of the Adeptus Ministorum (i.e., has served as a Chaplain) and wears a Rosarius, though it has no in-game effect.
Brother-Chaplain Hastor Crassos is armed with the fifth company's crozius arcanum, indicating his office as the Chaplain of the Fifth. He also is armed with a bolt pistol, frag grenades, and krak grenades. Crassos has had extensive training serving with assault squads, and sometimes takes to the field with a jump pack. He has earned the Crux Terminatus, and is an ordained priest of the Adeptus Ministorum, granting him a rosarius.
Brother-Captain Tauro leads the Sixth Company, one of the Lions Rampant Tactical Reserve Companies. He wields a masterwork boltgun as well as a power sword, and has frag and krak grenades. Like his fellow Captains, he too wears a rosarius to denote his service as a Chaplain, and displays an Iron Halo as his badge of office.
Brother-Captain Berian is lord of the Seventh, the other Lions Rampant Tactical Reserve Company. He fights with a storm bolter and power axe, and is equipped with frag and krak grenades. He wears a rosarius and displays an Iron Halo as his badge of office.
Brother-Captain Rhiannus is the Captain of the Eighth, the Lions Rampant Assault Reserve. He fights with dual lightning claws, and is armed with frag and krak grenades. He generally goes into battle with a jump pack, pouncing on his foes as a lion does upon its prey. He wears rosarius soul armour and displays an Iron Halo as his badge of office.
Brother-Captain Decius is master of the Ninth Company, the Lions Rampant Devastator Reserve. He is noted as the finest marksman in the Chapter, and can be seen striking down the Emperor's foes with a masterwork boltgun integrating a plasma weapon, as well as defending his firing lines with a finely-crafted power sword. He is equipped with frag and krak grenades, wears a rosarius, and displays an Iron Halo as his badge of office.
Brother-Captain Cyrico is lord of the novitiate Company, the Tenth. He fights with the traditional weapons of his office of Master of Recruits-- a masterwork boltgun and a powered gladius, as well as frag and krak grenades. He wears a rosarius and displays an Iron Halo as his badge of office.
And before you ask, out of pure boredom, I did make a roster for the entire Chapter. I'll post it up sometime in the Apocalypse section... or maybe in the fluff section. I'm not sure where it's better suited.
