Top 10 Space Marines Characters from Warhammer 40k

The current chapter master of the space wolves, Logan is considered in the fluff to be the greatest living warrior in the Imperium and was able to rival even his primarch.

Everyone either completely respects Logan Grimnar, or is afraid of him, Beheaded Grand Master Joros' for firing on his fleet, then beheaded Ghesmei Kysnaros. The whole inquisition is afraid of him

Has literally fueled Chaos Demon Lords and slain them.

Dante is the current chapter master of the Blood Angels and the oldest living space marine (that isn't a dreadnought or a Chaos marine) still living in the Imperium, not many people know how old Dante actually is. In the lore it's said their was a prophecy that a golden warrior would protect the Emperor on his thrown, Dante believes he is the warrior and the determination he has will make sure the prophecy comes ture.

With age comes experience!

Mephiston is the cheif librarian of the Blood Angels chapter and is one of the most powerful psykers in the Imperium. Mephiston is mostly well known for being the first Blood Angel to overcome the red thirst )which has plagued the chapter since it's creation) but not only that he came back stronger than ever and was reborn in the Lord of Death we known 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, kills an ork boss with one strike, threatens a warlord titen priceps in her own warlord titan (imperator class) - etc. etc.

Pretty cool dude

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 (A equivalent of a chapter master) until he was greatly injured in battle. Nowadays he is often awaken to tell the 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 seeks 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?

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'Sarno is the captain of the White Scars 3rd company and master of the hunt. He is what you would get is Genghis Khan rode a motorcycle into battle.

Cassius is the Master of Sancity and head Chaplin of the Ultramarines and 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 were utterly annialted by the Tyranids. This didn't go well as he nearly crushed to death by a rampaging Carnifex, but he was rebuilt by Apothecaries and had grown a deep hatred for Tyranids. He had become so good a killing the xenos he was inducted to 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.
