Wat.
Oh, sorry, it's Riku, I wasn't sure if I was going with Roxas or Riku when I first started typing this up, but went with Riku on the basis that he is stronger than Roxas.
All right, Magnus the Red's feats. Quotes are bolded.
Any Warhammer 40k afficianados who haven't read A Thousand Sons (And you really should, it's the best 40k novel I've ever read) should probably avert your gaze now, since I will be posting content from the book.
"The howling of the Wulfen built to a deafening crescendo.
And high above, those howls were finally answered.
Purple lightning split the sky and the heavens darkened with the sudden fall of night. A deluge of
black rain fell, soaking everything in an instant and saturating the air with the bitter taste of sodden
ashes. Ahriman looked up in shock to see a flaming giant descending from the highest reaches of the
Pyramid of Photep. The crux ansata rippled with pellucid green fire, and kaleidoscopic bolts of
lightning slammed into the ground, immolating dozens of the cursed Wulfen with every blazing
strike.
Cracks split the ground and the waters surrounding the pyramid seethed and boiled with anger.
Black waves crashed upon the shores, and the glass shards falling from the pyramid were caught in a
surging, sentient whirlwind that hurled them like spears to impale enemy warriors and skewer them
to the ground.
Ahriman felt an enormous build up of energy, and summoned all his strength to control his
body, knowing the mutations within his flesh would seek to throw off the shackles of his form and
unleash new and terrifying ones within him. Yet the painful surge of mutant growth never came, and
he looked up at the radiant being of fire and light that drew ever closer.
Magnus the Red was a glorious sight, his golden armour and wild red hair ablaze with aetheric
energy. His bladed staff threw off blinding arcs of lightning that destroyed armoured vehicles in
thunderous explosions. Magnus swept his eye across the horrified Space Wolves, and all who met
his gaze died in an instant as they were driven to madness by the stygian depths of infinite chaos
they saw there."
The first paragraph has Magnus flying down from the top of the Pyramid of Photep and killing dozens of Wulfen with single bolts of Warpspawned lightning. Wulfen are essentially mutant Space Wolf space marines, stronger and more durable than normal. Space Marines are incredibly durable in power armour, able to withstand monomolecular edged hypersonic weaponry or monomolecular chainsaws with a good chance of not being injured, and stuff. Oh yeah, and Magnus alters the weather itself.
The second shows Magnus splitting and cracking the groun around the Pyramid of Photep (Will provide a picture of smaller pyramids for reference soon), and boiling and blackening the water, while also shattering all the glass of the pyramid, before using telekinesis to weaponise it and kill more of the dirty Space Wolves.
The fourth paragraph has Magnus one-shotting several Space Marine tanks with blasts of loitnin'. Said tanks are more heavily armoured than the Space Marines that ride them, and have the chance to withstand, in the case of a Landraider, attacks that make tactical nukes look just downright silly, like Lances.
Now let me see... Other feats...
"The waters around the pyramid broke upon the shores, black as oil, and churning as though an
unseen tempest boiled beneath the surface. Space Wolves and Custodes ploughed through the water,
wading through the crashing spray to reach the pyramid in lieu of aiding Leman Russ in his battle.
Magnus swept his hands to the side, and the warriors on the water cried out in agony as it transformed into corrosive acid, burning through ceramite plates and rendering flesh and bone to jelly.
Thick rain fell, fit to drown the world, and the ground underfoot transformed into a stinking
quagmire from which writhing shapes like grasping hands emerged. Wounded warriors were
dragged down into the mud, struggling against their unseen attackers, but unable to resist being
pulled under to their doom.
Prospero was breaking apart, the veil between worlds cracking, and the maddening gibbers and
screams of the Great Ocean’s denizens drove men to their knees in terror. The assault on the senses
was total, and Ahriman could barely keep his feet as hurricane-force winds battered the pyramid,
tearing glass panes from its structure and breaking the silver and gold towers from its corners.
Thunder banged in the midnight sky, and heaving earthquakes ripped ever-widening cracks in the
ground, toppling what few structures of Tizca remained standing."
With a gesture, he could transmute water into a corrosive acid strong enough to melt the Space wolves and Custodians (Essentially like Space Marines, but more). Then, he transmuted and controlled the earth itself, dragging wounded warriors to their doom. After this of course, we are told Magnus is destroying the surface of Prospero, the planet, itself, causing hurricane force winds to batter the pyramid, and causing devastating Earthquakes that destroyed the parts of Tizca, a massive city, that survived the attack of the Space Wolves.
To elaborate on this next part of my post, I must describe Primarchs.
Primarchs are superhumanly powerful beings, living demigods with might beyond any mortal creature in the galaxy, and rivaled by few immortal creatures. They have a plethora of incredible feats.
"The child that would come to be known as Konrad Curze was first recorded as crashing through the surface and into the core of the night-shrouded world of Nostramo. The crust of Nostramo bore high quantities of the mineral adamantium, which provided the basis of the planet's immense mining and purifying industries."
Konrad Curze, Primarch of the Night Lords, and as a child, smashed through the surface of Nostramo, a planet, and into the core of the planet. He proceeded to crawl out. Do note that much of the crust consisted of adamantium, a super-durable material of awesomeness, and what that quote does not tell us is that Curze left a big ass ravine in the planet with his plummet. Primarchs are strong enough to hurt eachother with punches.
In terms of speed, on multiple instances Primarchs have moved so fast that Space Marines were incapable of seeing them move, being faster than their eyes can see. For reference, Space Marines on several occasions have perceived and deflected/dodged gunfire, in the middle of warzones. Primarchs are much bigger than said projectiles, and were incapable of being seen by them.
Anyway.
"Magnus drove his fist into Russ’ chest, the icy breastplate cracking open with a sound like
planets colliding, and shards of ceramite stabbed the Wolf King’s heart."
Magnus was capable of punching through Leman Russ' armour and the force of the blow actually broke the skin, and punctured one of Russ' hearts with his own armour. Russ is a Primarch, I should mention. Oh, and I should also mention that Magnus was amplifying his physical strikes with his mental powers (Though Magnus is the largest and one of the strongest Primarchs at base).
"A blade of pure thought
unsheathed from Magnus’ other arm, and he drove it deep into Russ’ chest through his shattered
armour.
The blade burst from Russ’ back and the Wolf King loosed a deafening bellow of pain. A chorus
of the wolves that were not wolves added their howls to that of their master. The two enormous
lupine monsters that accompanied Russ leapt upon Magnus, fastening their jaws upon his legs.
Magnus slammed his fist into the black wolfs head, driving it to the ground with a strangled yelp, its
skull surely shattered. With a bellow of anger, Magnus tore the white wolf from his leg with a
thought and hurled it away over the heads of the milling army at Russ’ back."
Can create blades from pure thought that cut through Primarchs with ease.
Then two gigantic Wulfen attacked Magnus, and Magnus shattered one of their skulls with a punch, and tossed the other away with a thought.
"Magnus’ eye snapped open and anger boiled over. His hand erupted in searing white fire, the
most prosaic and primal of the arts, and his chambers were filled with billowing flames, burning
everything within to cinders. Wood and paper vaporised in the white heat of Magnus’ rage, and
what little his despair had not destroyed, his rage consumed.
A column of blazing fire erupted from the summit of his pyramid, and a rain of molten glass
shards fell from the summit. All eyes in Tizca turned towards the Pyramid of Photep, the plume of
fire dwarfing that of the Pyrae.
Only the Book of Magnus remained inviolate, its pages impervious to the killing fire. Nothing was left of the mirror, its fused shards bubbling in a molten pool at his feet."
Destroyed the top of the Pyramid of Photep, and a plume of fire that was greater than that of the Pyrae, which is a cult in the Thousand Sons and is specifically referring to a constant geyser of Warpfire that sprouts from the top of the Pyrae Cult's Pyramid.

Those big ass pyramids in the distance are some normal Tizca pyramids, smaller than the pyramids of the different Cults or Photep.
"Magnus blinked and the creature erupted in flames, its piercing shrieks a paltry revenge for the
death it had caused. Its riders tried to hurl themselves from their blazing mount, but Magnus pinned
them to its back with a thought, and let them burn."
With a blink, he could set alight a big ass bird creature on fire, and with a thought pin its riders to its back, forcing them to burn.
He of course has more feats, but I can fit no more of it into here.
