Eidolon Interloper
is a crossover between Danny Phantom and The Legend of Zelda: Twilight Princess where a ritual by Zant to access the Sacred Real goes wrong and summons Danny to Hyrule instead.
Tropes
- Accidental Truth: When wondering how Danny could have gone from Kakariko to Castle Town and back in the same day, Rusl, half-jokingly, suggests that Danny can duplicate himself. While he can do that, that's not how he pulled it off.
- Armor-Piercing Question: When Telma asks how Danny defeated the Shadow Beast Zant sent to kidnap her, he completely freezes and doesn't answer the question at all.
- Brainwashed and Crazy: The mirror piece in the mansion does this, Danny only narrowly avoiding falling under its spell due to Link showing up at just the right moment.
- Black Speech: Ghosts can speak, but their speech is in a "dialect" Danny can only vaguely understand and speak. Poes can communicate in the same, but their speech is even more garbled, hinting at their corruption.
- Chronic Hero Syndrome: Danny, much as he just wants to find a way home, finds himself drawn to the Resistance and feels a drive in his core to help them.
- Closest Thing We Got: The fact that ecto-energy and Twili magic are more than slightly similar is why Zant's ritual connected to the Ghost Zone instead of the Sacred Realm, since Zant used the latter kind of energy to kill the Human Sacrifice the ritual sought out the realm that was the closest match after the Twilight itself.
- Crossover: Between Danny Phantom and Twilight Princess.
- Crossover Power Acquisition: When Zant's Shadow Beasts return from the Ghost Zone, they've managed to acquire ghostly powers.
- Dangerous Phlebotinum Interaction: Danny's powers don't interact well with Midna's Twili magic. When Danny phases Link and Midna through a cliff, Midna stays intangible for a minute or two even after Danny lets them go, and gains a fierce headache.
- Deader than Dead: Ripping out a ghost's core completely destroys it, afterlife and all, and Danny is thus horrified when he sees Link ripping out Poe souls.
- Entertainingly Wrong:
- Zant's ritual was meant to open a portal to the Sacred Realm, so he assumes that Danny is an entity native to said Realm, at least initially.
- The Resistance thinks that Danny's feats mean that he's a mage, though Ashei realizes otherwise soon enough.
- Danny believes that the Mirror of Twilight can send him back home, or at least the Ghost Zone. Even if it can, that's not what its description meant.
- When Danny reveals that he can see Poes, Link and Midna assume that he's a medium of some kind. Danny runs with it.
- Epic Fail: Danny is just horrible when it comes to swordplay, despite genuine effort to learn. Dora's knights tried to teach him and eventually gave up.
- Fake Wizardry: The Resistance initially assumes that Danny's ghostly powers are sorcerous. Danny does his best to continue this misconception.
- Forgot About His Powers: At Snowpeak Midna needs to remind Link that his wolf form has an enhanced sense of smell that he can use to track the Yeti.
- Healing Factor: Auru notices that Danny's leg injury healed rapidly.
- Human Sacrifice:
- Zant tried to unlock the Sacred Realm by sacrificing a girl descended from the Sages. He ended up opening a portal to the Ghost Zone and summoning Danny instead. After Danny escapes, he plans on doing more sacrifices...
- Apparently, some human cults on Earth have sacrificed people in an attempt to gather the attention and favor of some of the nastier entities of the Infinite Realms.
- Zant later sacrifices a Goron who's descended from the Sage of Fire to send his minions into the Ghost Zone.
- Invisible to Normals:
- The humans who are turned into spirits cannot see Danny in the Twilight, and even walk through him like he isn't there. Twili like Zant and Midna, and Link as a wolf, can see him.
- Normal people are unable to see Poes. Luckily for Danny, when he lets slip that he can see them, they just assume him to be a medium of some kind.
- The Magic Goes Away: It's noted that magic and mages have become rather rare in Hyrule in the present by the Resistance.
- Magic Misfire: Zant's Human Sacrifice ritual was supposed to use a sacrifice with the bloodline of one of the Sages to open a portal to the Sacred Realm. Somehow, it opened a portal to the Ghost Zone and sucked Danny through to Hyrule, the portal closing almost immediately afterward. Clockwork later reveals that since Twili magic has some similarities to ecto-energy, when Zant killed his victim with it the spell sought out the closest thing it could find with those elements, which was the Ghost Zone.
- Language Barrier: Danny can understand the people of Hyrule's spoken language, but despite it being identical to English, the written language is gibberish to him, much to his confusion.
- He later manages to start picking up the written language enough to get basic phrases and write his own name.
- Mythology Gag:
- When Danny is talking to Shad, he mentions a legend about humans living in the sky.
- When looking through the books for information on the "mortal goddess", Danny and Telma find a book about the Picori and an atlas of Koholint Island.
- When Rusl half-jokingly suggests that Danny can duplicate himself, Telma says that he's been reading too many stories about the Hero of the Four Sword.
- Sadistic Choice: Danny is afraid that he'll have to chose between saving Telma and going home to stop the Time Crash.
- Shapeshifter Mode Lock: Like Link, Danny can exist normally in a Twilight area, but is trapped in an alternate form, his ghost form in Danny's case. When Link restores the Light to one of these areas while he's unconscious, he shifts back before waking up.
- Sustained Misunderstanding: The Light Spirit attacking Danny when he tries to seek help from it, forcing him to attack it back in self-defense, causes Link and Midna to believe that he's evil.
- Time Crash: Zant's failed ritual somehow connected all of the various alternate timelines that Hyrule has to the Ghost Zone, and if it isn't fixed the best-case scenario is that the timelines will merge, causing potential devastation from people and places that clash too much. The worst-case scenario is that all the worlds involved will be destroyed.
- A Wizard Did It: In-Universe, after the Resistance assumes that Danny is a mage, he runs with it and invokes it as an excuse for anything too weird about himself.
- Wrong Context Magic: Danny's ghost powers are completely foreign to Hyrule and puzzle Zant. Midna's best comparison to what she can feel from him is the magic of the Twili, but she knows that it's not "quite" the same. This similarity comes up again as the reason for why Zant's ritual connected to the Ghost Zone instead of the Sacred Realm, since he used Twilit magic for killing the Human Sacrifice, the spell sought out the Ghost Zone in a Closest Thing We Got kind of way.
- Yank the Dog's Chain:
- Danny has managed to talk to the Sages, and knows that the "mortal goddess" he needs to talk to is Princess Zelda, giving him a solid lead on how to go home... and then Zant's barrier forms around the castle, which even his powers don't allow him to bypass, save potentially the Ghostly Wail, which he doesn’t want to risk trying due to the potential collateral damage even if it works.
- Danny thinks that the Mirror of Twilight could get him back to the Ghost Zone, but even when he finds it, it's broken.
