Silly man, first one to jump on the claiming band wagon, yet you never noticed there's ten of the things, one (Madara/Obito) or two (Naruto) just were formed into staves. I could also question where do you get the rikudo sage chakra considering tenseigan appears to be just a lookalike not the legit thing, and beast per ball idea too since Obito had three yet formed just the one. There is no 'bomb' either really, its just extends stupidly fast to pulverize anything in a wide area akin to jinton.
Not the place for it though, so commenting on tenseigan itself.
As anyone who read the thing would see, assuming its legit info of course with almost all info from movie missing still, if you guys want this it has to be modified fairly heavily if you want it on SL, cause its canonical self simply wont work. Comparing it to rinnegan, even that is not nearly as far-out if you cut out the part of combining specifically reincarnee chakras, not just genetics.
Tenseigan? Have to be 100% ootsutsuki (which appears to be a dead clan outside of Toneri btw), your own eyes sealed into the altar after birth most likely, I'd daresay visit the moon as well, implant somebodys byakugan without dying or organ rejection. And even then, despite the OPness, it'd be technically finite chakra, not to mention the as of yet completely unexplained fairly gross blob picture of Toneri being overtaken by some white gunk.
Only way I could think of on the fly of this possibly being a thing, is if whatever eye magic unlocking it would require would grant you the ability to make the chakra cloak outta the power you pour out of your tenketsu. Think of it as a compressed, constantly active molded kaiten if you will, lol.
As for it being some special uber chakra...uhh, prolly not. Even susanoo is ultimately the users own, instead of coming from some mystery source.
Edit: forgot preta path mention. Absorbing one would kill you unless you start breaking your own rules, since the nature energy innit would just petrify you.
