Marneus Calgar
From Lexicanum
Marneus Augustus Calgar is the Ultramarine's current Chapter Master and the Lord of Macragge. Following a skirmish against the Tyranid Hive Fleet Perseus in 976.M41, Calgar lost all four limbs as well as large areas of body tissue and his left eye. Now fitted with bionic replacements, he is more machine than man.
In battle he is armed and equipped with the Gauntlets of Ultramar, Power Armour and an Iron Halo. He sometimes wears the Armour of Antilochus into combat, as well as often leading a unit of the Ultramarines Honour Guard.
The Gauntlets of Ultramar were reclaimed by Primarch Roboute Guilliman from a Chaos Champion after the Gamalia Reclusiam Massacre.
As one might expect from an embodiment of the Ultramarine's nobility, Calgar is immune to fear and is resolutely courageous under fire; where lesser men would dive for cover when being fired upon, Marneus Calgar takes quick stock of the situation, decides the best course of action, and only if he so decides to leap into cover, then he will do so.
