Sigil
CrossGen.
1 Mark of Power (1-7; w Barbara Kesel; a Ben & Ray Lai).
[From CrossGen Comics: Sam wasn't anybody's hero. Samandahl Rey was
nobody special, just another washed-up ex-commando looking for work on the
wrong side of the gaming table on the pleasure world of Tanipal. Then all
hell broke loose in the form of an alien attack. After the dust settled,
Sam's best friend was dead, Tanipal was decimated, and Sam was left with
a strange scar on his chest...a mysterious mark that gives him access to
incredible power. And power of that level gets noticed. Now Sam is on the
run - from the alien Saurians, from the Tanipali Guardsmen, from gods and
creatures and governments alike, all of whom want nothing more than to seize
whatever mysterious all-powerful weapon Sam has in his possession. What
they don't realize, of course... is that Sam is the weapon.] 
2 The Marked Man (8-14, CrossGen Chronicles 4; w Mark Waid, Barbara
Kesel; a Randy Elliott, George Pérez, Mike Perkins, Scot Eaton, Rick
Magyar, Kevin Sharpe, Andrew Hennessy). [From CrossGen
Comics: Sam Rey is a marked man. Cashiered out of the centuries-old
war between the human race and the Saurian Empire, Sam was the farthest
thing from a hero. But when he was branded with a sigil granting him incredible
power, Sam became far more than a washed-up ex-commando. Now he's the focal
point of an intergalactic struggle as his newly-adopted homeworld faces
a full-scale Saurian invasion. Sam's only hope may be the last option he'd
ever choose: an alliance with his greatest enemy, the Saurian prince responsible
for the death of Sam's closest friend.] 
3 The Lizard God (15-20; w Mark Waid, Barbara Kesel; a Eduardo
Barreto, Mike Perkins, John Dell, Scot Eaton, Paul Pelletier, Andrew Hennessy).
[From CrossGen Comics: Samandhal Rey was a soldier
in the Planetary Union army, and a good one, too. But that didn't stop the
army from bouncing him. Embittered and virtually friendless, Sam wandered
the outer fringes of the galaxy until a strange being bestowed on him a
mark of great power. Now that sigil may be the key to victory against the
marauding Saurian empire, and Sam finds himself back in the center of the
centuries-old conflict. The ex-commando is now Field Commander of the Union
Army, charged with defending mankind against a Saurian armada. The invaders
are led by Khyradon, the self-styled god whose strange powers seem to mirror
Sam's own, and who has taken control of the Saurian empire in a frenzied
push to eradicate humanity once and for all. Khyradon's forces descend on
a remote outpost in what could be a decisive battle, but as Sam readies
his troops, something goes horribly wrong...] 
4 Hostage Planet (21-26; w Chuck Dixon; a Scot Eaton, Andrew Hennessy, Rudy Nebres). [From CrossGen Comics: The human race has been at war with their merciless enemy for centuries. Now a fanatical warlord leads the forces of the Saurian Empire in a surprise attack on the human homeworld. For Khyradon, only total annihilation means victory. And so, the fate of an entire race rests on one man. Will the mysterious powers granted to a common grunt be enough to turn the bloody tide of battle from the frontiers of the Planetary Union? Can Sam save his species from extinction?] 
5 Death Match (27-32; w Chuck Dixon; a Scot Eaton). [From Checker Books: The next galactic graphic NOVEL IS HERE! Humanity's last hope for survival is a grizzled mercenary, and to save us all Samandahl Rey must face the mighty Suarian Weapon master. But what will Sam be forced to unleash to achieve his victory?] 
6 Planetary Union (21-26; w Chuck Dixon; a Scot Eaton).
