Senshi of Thundera
is a crossover fanfiction written by HistorianofAlt on Space Battles. It's mainly focused on Ranma ½, Sailor Moon and ThunderCats but there's a lot of small cameos from other franchises.
When the Silver Millenium collapsed, Thundera, turning inept to support life, forced the survivors to go into hibernation and wait for better days. Now, centuries after the disaster, Snarf awakens, ready to seek for his missing lord Lion-O's reincarnation and entrust him with the rebuilding of Thundera.
Ranma is decidedly ambivalent about the whole thing. Genma blames Fate for this.
Contains the following tropes
- Barrier Maiden: The senshi were the linchpin, ensuring every world ruled by the Silver Millennium could sustain life. When they died to be reincarnated in the future, at least Thundera and Saturn became wholly unlivable, causing millions of deaths.
- Because Destiny Says So: When a furry talking creature proclaims Ranma is an alien prince reborn meant to restore life to a moon of Saturn, Genma and Soun basically shrug it off as Ranma's dharma – his soul trajectory in the Buddhist tradition. If it's meant to happen, then it will happen.
- Bigotry Exception: Snarf isn't the greatest fan of the Silver Millenium, and is very dismissive of the Senshi. However, he's nothing but respectful towards the Princess of Saturn, who was Thundera's overlord and did her best to protect the Thunderians when they asked for her help.
- Break the Scientist: Soun and Genma made a point of avoiding physicists because they take it badly when a martial artist casually ignores reality to do cool stuff. Also, doctors have nervous breakdowns when they see Ranma's near miraculous recovery rate, so it's better to ask for a qi healer.
- Crossover Relatives: Not only is Ranma related to people from every work by Rumiko Takahashi, Ami Mizuno is the younger cousin to the Tendo girls.
- Cursed with Awesome: Ranma isn't particularly overjoyed to transform into a humanoid feline, but on the other hand, his new transformation overrides his Junsenkyo curse so he won't turn into a girl anymore. And his Thundercat form is the very epitome of macho manliness.
- Easily Forgiven: Soun is not very happy to learn Ranma knew about Ryoga's Jusenkyo curse and nonetheless let him sleep in Akane's bed. However, Ranma gave his word and oaths are very important, especially when it comes to magic – breaking one can actually kill you – so the Tendo patriarch is understanding of the matter.
- Hero of Another Story: Genma bluntly tells Ranma that the world doesn't revolve around him. His life might be one of the strangest recorded by the Saotome family, but it doesn't prevent other people from having their own adventures – such as his cousin Kagome being fated to time-travel back to the Sengoku era, marry a half-dog demon, and become the ancestress to the Tendo family.
- Mirror Character: Genma Saotome manages to be a far better person than Sabato Rokudo because he's shown genuinely worrying about his wife and son, turning tricks and scams only to keep themselves afloat. On the other hand, Sabato has no remorse driving his own cousin crazy then preying on her mental illness in order to steal money.
- My Hovercraft Is Full of Eels: The reason why Snarf insists for people to be on a Last-Name Basis with him. His given name Osbert is supposed to mean "he who monitors life-giving dynamic flow", but when humans try to use it, their lack of familiarity with the snarf language makes them tell "waste disposal humper" – and that's the least offensive way to screw it up. At least when calling him Snarf, they can't do worse than "minion".
- Nice Job Breaking It, Hero: After losing several senshi in Beryl's terrorist attack against the Lunar Palace, Queen Serenity used the Silver Crystal to ensure they would reincarnate in the future. Unfortunately, it killed Sailor Saturn by ripping out her soul just as she was helping Lion-O defend the Thunderian citadel – and because the senshi were Barrier Maidens, at least two planets were left unable to sustain life in the immediate aftermath. Needless to say, Snarf is deeply bitter and not the greatest fan of the late Queen.
- The Ophelia: Courtesy of her cousin using her for a scam, Nodoka was forced to remember all her previous lives – and it's implied some were very traumatizing – leaving her unable to care for herself and potentially a danger to her young son. Genma is very affected by the situation and muses that the worst outcome in thid thing would be having his wife back once in a while, only to lose her again the next day.
- Power Misidentification: When meeting Ranma after the martial artist unlocked his Thundercat inheritance, Adam Pierson is noticeably wary – obviously thinking Ranma is an Immortal, and asking if the younger man plans to master swordsmanship in the future.
- Really 700 Years Old: When the Silver Millenium still stood, an Isu citizen wasn't considered fully mature until their 125th birthday and had a lifespan of a thousand years. The other species had a much reduced yet still impressive lifespan of two or three centuries.
- Undying Loyalty: Snarf went into suspended animation for millennia in order to wait for Lion-O to reincarnate. When informed of Ranma's existence, he immediately seeks the young man to give him the Sword of Omens, inform him of his destiny, and help him to become a man worthy to take the throne and restore Thundera's biosphere.
- Unequal Rites: Magic users tend to focus on mana manipulation; martial artists favor chi manipulation. It's possible for someone to wield both energies, but it has never happened until Ranma.
- Weirdness Magnet: The man who became the ancestor to the Saotome lineage was the illegitimate son of Oda Nobunaga, who in this universe was an avatar of Mara – Genma blames this connection to the mystical for the fact that every single generation of the family since is drawn into wacky adventures, such as his son being a reborn alien prince or his niece traveling back to the Warring States Era to fall in love with a half-demon.
