Top 10 Space Marines Characters from Warhammer 40k

The current Chapter Master of the Space Wolves, Logan is considered in the lore to be the greatest living warrior in the Imperium, able to rival even his Primarch.

Everyone either completely respects Logan Grimnar or is afraid of him. He beheaded Grand Master Joros for firing on his fleet, then beheaded Ghesmei Kysnaros. The entire Inquisition is afraid of him.

Has literally fueled Chaos Daemon Lords and slain them.

Dante is the current Chapter Master of the Blood Angels and the oldest living Space Marine (who isn't a Dreadnought or a Chaos Marine) still in the Imperium. Not many people know how old Dante actually is. In the lore, it's said that there was a prophecy that a golden warrior would protect the Emperor on his throne. Dante believes he is this warrior, and his determination ensures that the prophecy will come true.

Mephiston is the Chief Librarian of the Blood Angels Chapter and is one of the most powerful psykers in the Imperium. He is primarily known for being the first Blood Angel to overcome the Red Thirst (which has plagued the chapter since its creation). Not only did he overcome it, but he also returned stronger than ever, reborn as the Lord of Death we know today.

Awesome. Totally not being prejudiced as a Blood Angels player.

This man is literally so angry, he is actually serene.

I've dug my grave in this place, and I will either triumph, or I will die.

Stopped a Princeps from dying, killed an Ork boss with one strike, and threatened a Warlord Titan Princeps in her own Warlord Titan (Imperator-class), etc., etc.

Bjorn is a Dreadnought of the Space Wolves and the single oldest loyalist Space Marine still alive. He has served since before the Horus Heresy, and after the disappearance of Leman Russ, he became the first Great Wolf (the equivalent of a Chapter Master) until he was gravely injured in battle. Nowadays, he is often awakened to tell stories of the past, mostly about Leman Russ.

Oldest living Legionnaire who fought by the side of Russ and helped shape the history of the Imperium.

Vulkan He'stan is the Forefather of the Salamanders Chapter. Part of his duty is to seek the artifacts his Primarch Vulkan left behind. He still searches for four of the nine objects that were left and is determined to find them. On the tabletop, he is a good choice to lead Space Marine armies.

One of the noble Salamanders. How can you not choose him?

Ezekiel is the Grand Master of Librarians of the Dark Angels Chapter. He holds the titles of Holder of the Keys and Keeper of the Book of Salvation.

Kor'sarro is the Captain of the White Scars 3rd Company and Master of the Hunt. He is what you would get if Genghis Khan rode a motorcycle into battle.

Cassius is the Master of Sanctity and Head Chaplain of the Ultramarines, currently serving in the Deathwatch. He made his name in the First Tyrannic War when he attempted to save the Northern Polar Fortress after the 1st Company was utterly annihilated by the Tyranids. This didn't go well, as he was nearly crushed to death by a rampaging Carnifex. However, he was rebuilt by Apothecaries and developed a deep hatred for Tyranids. He became so proficient at killing the xenos that he was inducted into the Deathwatch for his skills. Cassius is also notable for being one of the few Ultramarine characters who isn't written as a Mary Sue.
