- Why else have we seen Odin in the Thor movies, or in the series Vikings in the last few years? He's even in The Almighty Johnsons as a Mr. Wednesday Expy!
- Media outright states that one of his European counterparts had taken the same deal as Ostara, so that makes sense.
- What 'real Odin'? There isn't a 'real Odin', each of his incarnations is influenced by the society in which his believers live in. The Icelandic Odin, for instance, isn't any more the Prime Odin than Wednesday is. He's just different.
- Easter/Ostara famine = She suck the life out of plants which includes crops
- Odin-war= He incites the war
- Czernobog-Death= look at his hammer
- If the series follow the books then Mr. World is conquest or Bilquist is Pestilence
- Jossed. A newer, sleeker Technical Boy has replaced him, this having been a recurring thind done since the 1930's (if not earlier).
This theory is contingent on the idea that people who have been watching the series has read the book (or at least has researched it) and have learned the twist that Mr. World is Loki. In the series, Media has realized that war is inevitable and decides to embrace the "gods of progress" idea that her pantheon predicates on and has herself upgraded, becoming New Media after spending a sizable amount of time within the internet and learning how humanity's sense of entertainment and interaction is evolving and evolves with it.
Loki is a trickster god, and in many mythologies, tricksters do their duty not by direct confrontation, but through disguises and wit. What better way to destroy a group of powerful people than from within? Sure he could have gone to Mr. World as himself and asked to be "rebranded" like they have offered everybody else, but Loki is notorious for being the kind of guy that bites the hand that feeds him, so it is unlikely that anyone would trust him regardless of how good he behaves. Instead, Loki uses his natural ability to disguise himself (Sleipnir being proof that he can change gender as well) and takes on the guise of an unassuming being who also has a habit of changing form. It is likely that he had been following the New Gods, had either incapacitated or killed Media and took her place, successfully using the logic of how the gods operate to his advantage.
The moment New Media appears, the power dynamic among the new gods has been upset. "She" appeals to Mr. World's Control Freak personality by displaying unflinching optimism towards his plans. Because New Media is a New God of information (and what better currency for buying mischief is there other than information?), she can do everything that the Technical Boy could do (being the New God of Technology and the Internet) but with literal thousands of years of experience by comparison. This puts Technical Boy on edge, as not only does he not work well with strangers (and New Media is very strange), but he is already on thin ice with Mr. World as is. All she does is provide that last push (convincing him that she can do TB's job better than he can) and Mr. World "retires" the Technical Boy. That's two New Gods down.
While Mr. World seems to possess some level of omniscience, it is not infallible, or else he would not find Argus and his contributions as valuable as he did. Loki, being the witty son-of-a-bitch that he is, would be clever enough to avoid his suspicions up until she finds a way to off him, or at least somehow convince him to call every other New God together for that big battle just like he wants.
- Additionally, Sweeney was a god himself, and odds are bringing a divinity back to life just works differently. According to the lore, the gods get their powers from believers and their worship of them, that's what keeps them alive. So in theory, if a mortal were to worship him hard enough, Sweeney could be reincarnated. However, reincarnation is not resurrection and it might not be the same Sweeney who comes back to life since each god is shaped by their believers (who are themselves shaped by the society they live in, that's why there were multiple Jesus for example).
In season 2, it has been established that Technical Boy has existed in multiple forms, vague on whether or not they qualify as different gods who look similar due to sharing a domain (like how Daniel looks vaguely like Morpheus in The Sandman) or if it's a form of Resurrective Immortality. In season 3, Technical Boy responds to Shadow hitting him for his attempted hanging by clarifying that he apologized for it already despite this version of Technical Boy being a different version, implying that it is the later explanation. So far the oldest version of Technical Boy we've seen had existed showcasing rudimentary robotics at the World's Columbian Exposition (1893), so we can safely assumes that it goes back farther than that, possibly to the point where he could have been brought to America by the belief of immigrants same as the rest of the Old Gods.
Now who he was is still a mystery. Technical Boy has only really met with Bilquis and Wednesday as far as fellow Old Gods are concerned. Bilquis is made out to be ancient even by most Old God standards (being the Biblical Queen of Sheba, a Love Goddess in Babylonian times and an African Goddess before then), and Wednesday is from the Viking Era (the Vikings having existed since around the late 8th century), having apparently been brought to America when Vikings discovered it (10th century). Neither of them have ever acknowledged Technical Boy as anything other than a New God, but Bilquis is an extremely localized Goddess (mainly to the Middle-East) that came to America back in The '70s and Wednesday has been in America longer than it was officially a nation, so it is possible that they simply have never met Old!Technical Boy before he became the New God he is today.
Safe to say who ever he was, he was a god associated with innovation (like a Forge, Architectural or Agricultural God) of some kind and he would have to be from a predominantly caucasian culture (or at least one adopted and vilified by white people like the Greeces and Romans). It is unlikely that someone as white as Technical Boy was originally cooked up by a Qing Dynasty silk-manufacturer or a Mayan architect.
- Confirmed. In "Tears of the Wrath-Bearing Tree", Mr. World reveals to him that Technical Boy is actually the Anthropomorphic Personification of Human Innovation, "Artifact One" being an old flint-stone used when man first learned how to make fire. The reason why he can't remember this is because with every era, he suffers from Identity Amnesia, though if the last version of him is any indication, this could be a result of each version of Technical Boy dying in someway, only to be reborn as a new person.
