If it were up to me, Apocalypse can own a cerebro unit on his head theme on a pharaoh’s nemes headdress. And an Egyptian beard. And among his psychic powers be the power to forge weapons of psionic energy including swords, spears, axes, flails, maces, hammers, sickles, knives, and more. It rock to see Apocalypse do this to melee fight the alicons.

Apocalypse; The future came to me in the Celestial’s crafts. I’ve embraced it and merge with the technology so I’d lead the evolution of the human race.

If MLP crossover with Marvel and met Apocalypse, it rock.
One voice actor which fit be Keith David. He who voice Goliath and Thailog in Gargoyles, T’Challa/Black Panther in the 1990’s Fantastic Four, Solovar in The Flash, Tubelot in The Legend of Tarzan, Hordak in Masters of the Universe: Revolution, Okotto and the Narrator in Princess Mononoke, Despero in Justice League, Doctor Facilier in The Pricness and the Frog, the bear monster in Ben 10, the turkey chief in Free Birds, and more. He fit this monstrous fusion of brain and brawn; especially when he uses big words.

Apocalypse be the X-Men rogue I wish the MLP meet the most. Gen 4 and Gen 5. The oldest and darkest mutant. Able with psychic powers, super-strength, super-speed, a healing fator, super-intelligence, technoparthy, sizeshifting, shapeshifting, teleporting, and forcefield-forging. And a master puppeteer.
It rock if he was the very mastermind behind the Avengers Cyvyl War to arrange his release from his ancient prison, with AMgneto and Tony Stark as his biggest pawns. And Spider-Man reveal as the Chosen One to lead the Avengers to victorya gainst him with help froM Galactus and the Infinity Stones.
If the MLP ones got invovle, Apocalypse can use the Marer Do Well and Walking Dead hoaxes and Twylight’s gambit with Queen Novo’s gem and betraying the CMC for Cozy Glow as wella s her Lesson Zero sin to show her hypocrisyand to try and tmept a certain Wonderbolt to kill ehr. But it rock if the Wonderbolt refuse; and if she said how Spider-Man, Professor X, Shang Chi, the Black Panther, the Silver Surfer, MJ, Wolverine, Jean, and Thor prove more worthy to be gods than him.
