I told you guys I'd give a more in depth list of feats and after going through some various threads online I've found some rather convincing ones:
Much respect to the comic vine and reddit sub-forum respect threads of course. I'm focusing on combat, strength, durability and reaction time for this list.SPEED/REFLEXES/REACTION TIME
Covering 19 feet per step while running:
“'Disperse!' bellowed Astelan, sprinting to his right. His power armour took him across the ground in huge leaps, covering half a dozen metres with every pace.
-Tales Of Heresy Page 304
Deflecting Bolter rounds from a Bolter set to automatic fire:
"Vendatha pulled the haft-trigger, and his spear underslung Bolter cracked off a stream of rounds on full auto.
Argal Tal saw it coming. The swords of red iron smashed the first three bolts aside, their power fields strong enough to detonate the shells as they streaked towards the Primarch's heart."
-Tales of Heresy Page 404
Slapping Bolter rounds out of the air:
"Plague Marines shot at him. Those shots that Gammadin did not slap out of the air, he took against his shoulder plates. Shrapnel puffed against him."
-Blood Gorgons, p.159
Ability to process analyze and decide the best course of action within nonseconds:
"The Word Bearer is almost unrecognisable. For a nanosecond, the figure registers to Luciel as an unknown, a threat.
Transhuman responses are already there, unbidden. Adrenaline spikes to heighten an already formidable reaction time. Muscle remembers. Luciel wears his boltgun, an oiled black pit bull of a weapon, in his thigh holster. He can draw, aim and fire in less than a second. The range is six metres, the target unobstructed. There is no chance of missing. Maximus plate, frontally augmented, might stop a mass-reactive shell, so Luciel will fire two and aim for the visor slits. The airgate skin-sleeve is self-repairing, and will survive las-fire damage, but a bolter shot will shred it open, so Luciel also braces for the explosive decompression of a ricochet or a miss-hit. At a simple, subconscious neural urge, boot-sole electromagnets charge to clamp onto the deck plates.
He can make a clean kill headshot in less than a second and a half, two rounds for kill insurance, and probably protect the atmospheric integrity of the airgate.
All this, all this decided, unbidden, instinctive, in less than a nanosecond."
-Dawn Of War Omnibus Page 258
From a complete standstill, leaping 4 meters high:
He leapt. His explosiveness was incredible, clearing four metres from a standstill.STRENGTH
-Blood Gorgon's Page 69
Ripping a man in half effortlessly:
One of the Isstvanian soldiers ran at him, shrieking and aflame, and pulled Temeter into an embrace. The captain let the flamer drop from his grip and ripped the man in two, tearing him apart effortlessly. He beat out the flames and grimaced as the rest of his troop waded in and finished the task.
-The Flight of the Eisenstein p.250
Not even straining to lift half a ton:
During a particular training exercise in ambush methods, a fledgling Disciple was crushed by his own poorly-rigged log trap. One of the four - Gabre - simply levered the half-tonne log off the dead man and Mautista saw with his own eyes the way Gabre barely strained to lift it.
-Flesh and Iron Page 118
Backhanding a 440lbs dude sending him flying.
Laughing, Sica backhanded one of the hooded men with the ridged knuckles of his gauntlet, snapping his neck and throwing two hundred kilos of brutish soldier back into his comrades.
-Blood Gorgon's Page 64
Ripping open tanks and such:
Tanks did not slow the Space Marines down. They clambered up on to them, ripped off durasteel hatches as if they were made of paper and dropped grenades into the interior.DURABILITY
-Angel Of Fire
All Marines have a very efficient healing factor showcased here:
Red runes winked into life on his visor as his armor was torn open in half a dozen places. He felt searing pain and cursed as he yanked a plate-sized piece of sizzling shrapnel from his leg. Almost instantly, he could feel the Larraman cells clotting his blood and forming a protective layer of scar tissue over the wound. He had suffered much worse before and shut out the pain.
Ultramarines Omnibus Page 22
Tanking a grenade point blank:
They laughed as they worked, a drywicked laughter that was frightening in its intensity. From behind the circular saws of an industrial rockcutter, a hooded man lobbed a rock at Sica. He heard a whistling sound and he turned the slab of his shoulder pad towards the missile. There was a flash of light. Even with his eyes closed, Sica’s vision strobed red and bright yellow. It had been a grenade. The explosion pushed Sica slightly and made him grunt with annoyance at his own carelessness. He shot the man off the industrial saw, quickly, as if ashamed.
-Blood Gorgons Page 63
Tanking lightning that glasses the ground when it hits:
We’re exposed out here,’ Bulle muttered. ‘Let’s get back into the forest.’Tarvitz was amused. Bulle made it sound as if the stalk thickets were safe ground.Giant forks of lightning, savage and yellow-white phosphorescent, were searing down into the open space, explosively scorching the earth. Though each fork only existed for a nanosecond, they seemed solid and real, like fundamental, physical structures, like up turned, thorny trees. Three Astartes, including Lucius, were struck. Secure in their Mark IV plate, they shrugged off the massive,detonating impacts and laughed as aftershock electrical blooms crackled like garlands of blue wire around their armour for a few seconds.
The storm above grew still more ferocious. Five more men were struck. One of them, Ulzoras, was actually knocked off his feet. They saw fused, glassy craters in the ground where lighting had earthed with the force of penetrator missiles.
-Horus Rising Page 232
A few feats that I'd like to mention that I haven't managed to get exact page numbers for because I don't want to look through all of my novels to find the pages.
Forrix a Terminator of the first company of the Iron Warriors was able to take a Leman Russ battle tank falling on top of him and then flipping it over his own body to smash other soldiers behind him. Leman Russ tanks weigh about 60 tons.
Learchus - a standard marine of the Ultramarines legion who was tasked with what amounts to bodyguard duty had to get a politicians vehicle out of some mud that it was stuck in. This vehicle weighed about as much as a car. He casually without any visible effort whatsoever just picks the back of the vehicle up and pushes it forward. The ease with which this was doen cannot be understated.
It's very important to note that the marines performing these feats were not particularly powerful or "better/stronger/more powerful" than any other Astartes in any other legion. These physical capabilities extend to every legionairre. It's literally coded into their genetics from each progenitor Primarch.
The "main characters" of the lore have feats that make these men weep.
For example, Peturabo the Primarch of the Iron Warriors was able to kill 30 Terminators of the Imperial Fist Legion with fucking EASE. Terminators can do everything I just listed except they can tank so so much more, are far stronger and weild weapons capable of leveling most anything you can think of on a field of battle. Peturabo DESTROYS these guys like it's not even a thing. Fucking annihilates them. Extinction status. It's real as fuck bros.
So yeah, much help from existing sources but it's always nice to have this stuff readily available on this site.
