You can combine the aesthetics by having characters from both universes wear a mix of the iconic armors. For instance, a character could have the plate armor design of a Warhammer Space Marine but with the color scheme and runic markings inspired by Warcraft's dwarves.
The armor and weapon designs can be merged. Dovahkiin's iconic dragonplate armor could inspire new skins or even new item designs in League of Legends. The weapons, like the dragonbone warhammer, could be reimagined as a powerful weapon for a champion in the game, with similar aesthetics but adapted to fit the game's balance.
Well, you could start with a portal that connects the Percy Jackson universe and the Warcraft universe. Sylvanus, being a powerful entity in the Warcraft world, could be interested in the unique powers that Percy has. In a fanfiction, Percy might be on a quest in his own world and accidentally stumble through the portal. Sylvanus could see him as a potential ally or threat. He could then team up with some of the more nature - friendly races in Warcraft, like the night elves, due to his connection with Sylvanus, who also has a connection to nature. They could fight against common enemies, such as the Burning Legion.
The aesthetics blend in interesting ways. In Halo, you have the bright, energy - based elements like the plasma weapons. When combined with Warhammer's dark and moody aesthetic, it can create a unique look. The Forerunner architecture in Halo, with its large, geometric structures, can be juxtaposed with the gothic spires and cathedrals of Warhammer. It's like a meeting of the future and a dark, fantastical past. You might see a Halo UNSC base built within the ruins of a Warhammer city, or vice versa, and the different styles would clash and merge in a visually appealing way.
One idea could be a crossover of the two universes' races in a battle for a powerful, ancient artifact. For example, the Orcs from Warcraft and the Orks from Warhammer could form an uneasy alliance against a common enemy like a powerful demon lord that threatens both worlds.
Well, in terms of the aesthetics, the dark and gloomy atmosphere of Resident Evil can be enhanced with the more neon - like, glowing elements of the Black Light. For example, infected areas could have a strange mix of the Resident Evil's dilapidated buildings and the Black Light's glowing veins running through the walls.
To combine the aesthetics, start with the characters. Red Alert has soldiers in military uniforms. They could be given some elements of Inferno's style, like having a small infernal symbol on their helmets or a bit of his fiery energy running through their weapons. For the vehicles, instead of just the normal metal look, they could have a molten look around the edges, as if they've been in contact with Inferno's world. The sky in the combined universe could be a mix of the smoky, war - torn sky of Red Alert with some of the strange, otherworldly colors that are often associated with Inferno's world, creating a really unique and visually striking atmosphere.
Combining the magic systems of Fairy Tail and Warcraft can be quite complex but also very interesting. For starters, the rune - based magic in Warcraft could be incorporated into Fairy Tail's magic. Mages in Fairy Tail could start using runes to enhance their spells or create new ones. The teleportation magic in Fairy Tail could be combined with the portals in Warcraft. This would allow for faster travel between different locations in both universes. Additionally, the transformation magic in Fairy Tail could be influenced by the shapeshifting abilities in Warcraft. For example, a Fairy Tail character who can transform into an animal could learn to take on more Warcraft - specific forms, like a Tauren or a Worgen, and gain their unique abilities.
The sleek, high - tech look of Halo's UNSC and Covenant ships can contrast sharply with the gothic, ornate designs of Warhammer's spacecraft and architecture. In fanfiction, authors might describe how the angular, metallic forms of Halo coexist with the spiky, daemon - influenced aesthetics of Warhammer. For example, a UNSC base on a Warhammer world might look like a strange outlier, or perhaps over time, it starts to adopt some of the local, more flamboyant design elements.
In fanfiction, the combination might involve a device or spell that merges the two power systems. Maybe a Warhammer 40k tech - priest discovers a way to infuse the essence of quirks into their machinery. This could lead to the creation of weapons with quirk - like abilities, like a bolter that can shoot fireballs similar to a hero's quirk. It would completely change the dynamics of warfare in the Warhammer 40k universe.
You could start with the color palette. In 'The Dark Knight', there are a lot of dark and moody tones. In a Star Wars fanfic, you could describe planets or spaceships with similar color schemes. For example, a Sith - occupied planet could be a dark, gloomy place with a lot of blacks and grays, like Gotham in 'The Dark Knight'. Also, the way characters are dressed. Stormtroopers could be given a more 'Dark Knight' - like look, with some added leather or more menacing - looking armor.
