Alexis Polux was known for his massive physical size, as he stood taller than all his Battle-Brothers. Even without his Power Armour on, he still dwarfed most other Astartes warriors. Such was Polux's strength and focus of will, even for one of the Legiones Astartes, that he was able to deliver a single crushing blow with his Power Fist as easily as one of his brothers might have swung a sword. Besides his physical prowess, Alexis Polux was a highly skilled commander and a formidable tactician, particularly in the fields of void-borne combat and Zone Mortalis operations. Polux's rise through the ranks of the Imperial Fists was meteoric, as his superlative combat skills and potent tactical skills saw him raised to command other Space Marine Veterans with far more practical experience.
