Tobirama wakes to bird song and wind through the leaves. This wouldn't nearly be half as surprising if he hadn't been killed by the Gold and Silver Brothers, last time he was awake. It takes more time than he'll ever admit to realize that he's not where he was killed. In fact, he's clear on the other side of Fire Country, right on the border.
He's also not in his usual armor but rather a light weight alternative made more for quick, in and out assassinations than frontline battle. His happuri is missing, as well, which means his hair is left to drip in front of his face in an eternally annoying way.
Then there's the strange chakra clinging to his, more plant-like in nature than even his Anija's had been. He frown and begins to pull and push insistently at the strange chakra, aiming to remove it via drowning (or the chakra equivalent of such). He stifles a hiss of pain when the foreign chakra strikes out, sending a sharp, piercing pain through his head and chest. Something he'll have to work slowly at, then, instead of just rushing through. He reaches his chakra out towards Konoha, searching for his students and hiraishin-
-only to flinch back at the fiery, overwhelming nature of Uchiha Madara's chakra and, beside it, Uchiha Izuna.
Well, considering only he knows anything about Edo Tensei (and he can't even get the damn jutsu to work properly), he's going to assume something has gone very wrong. Wrong as in accidentally-dropping-himself-into-the-wrong-universe. Now that he's figured out this much, the next thing to ask is how. And, of course, his alternate self's status in this world.
(Is his alternate self now in his original body? If yes, he's dead. If no, was he killed when Tobirama was shoved into this body?)
Tobirama searches himself for any clue he can get. Konoha's symbol is missing from all of his new supplies, as is the symbol of the Senju.
Madara and Izuna's chakra pulls insistently at him. He has a bad feeling about this. Where is this version of his brother?
He has only a few hiraishin kunai and markers scattered sparingly across his chakra sense in a nonsensical pattern that seems designed more for easy escape than the easy defense of one particular location. Several of these markers are on the other side of the border, in Kawa, and even a few lingering on the edge of his senses in Suna and Ame.
His mind returns, again, to the very much alive Uchiha brothers and his own missing brothers.
His alternate self, as far as he can tell, has abandoned Konoha.
He and Madara have switched fates, he realizes with a sinking feeling. He would ask why him and not Hashirama but the answer is obvious. Hashirama would never put anyone above a chance at peace, not even the life of his younger brother. And if the Madara of his own universe had had this chakra clinging to him, manipulating him, even, then his actions start making more sense than they already had.
If he is Madara, that must make Madara him. Izuna would be left with the position of Hashirama. Tobirama's alive so his alternate self must not have attacked Konoha yet and brought the Uchiha brothers down upon himself or, as is more in character, he had decided for a stealthier way to destroy Konoha. Perhaps his other self hadn't even planned to take Konohagakure down.
He can't quite convince himself of this.
Either way, his body in his original world is most certainly dead. If he were to return to that world, he'd likely be shoved in his old body, leaving him just as dead as he should have been. He'll be staying here, then. This world seems to be behind his own, as the First Shinobi War doesn't seem to have started just yet. If he can diffuse the tension, he may be able to keep his village, students, and family in this world out of quite as much danger.
For now, though, money is a necessity. He has no village or clan to support him so that will take some time to adapt to. Building a reputation amongst clients as trustworthy is the only way he's going to get any good missions.
