Xavier

A bro among a Chapter of bros. Note how his Crozius Arcanum looks less like the traditional ones and more like Mjolnir. Because that's how he rolls.

Seems he just saw a bunch of traitors. That's why he's grinning.

Xavier (No not that one...) is a historic member of the Salamanders Space Marine chapter and regarded as the greatest Chaplain the chapter has ever known.

Even as a novice he was noticed to be talented and dedicated and his mentor, Chaplain Hasdrubael took him under his wing and taught him the Chapter's methods. When Hasdrubael was slain during an attack on a chaos battleship, Xavier took command and manfully completely destroyed the chaos scum.

He was regarded as the epitome of the Chapter's values, embodying them more then any other marine in the Chatper's history. Proudly upholding the chapter's Promethean Cult, he was a powerful orator and inspiring leader and anyone from new scouts to even the Chapter Master wanted to sit in on his lectures and hear him speak.

As a sign of how much of a bro the Salamanders thought he was, they gave him 'Vulkan's Sigil', said to have been used by the big man himself. It was a sign of how much regard they held for him.

He had a pretty heroic ending given to him, battling alongside his brothers against their hated foes the Dark Eldar and kept on fighting regardless of his wounds until all of the foes were dead and then allowed himself to die. Despite being dead you can still use his miniature, meaning new adventures await our mighty hero.

HERESY ERA XAVIER

In one of the Horus Heresy Artbook Series, there is a Salamander's Chaplain by the name Xavier. Note that this Chaplain lived ten thousand years before the actual Xavier. Coincidence? Ancestor? Previous incarnation? Who knows.
