Will KOing Thundurus give it a chance to be shiny?

Question

So to SR for shiny Thundurus/Tornadus you have to save and look at the Pokedex right? So if I KO it and battle the E4 when it respawns will it have a chance to be shiny even if it wasn't shiny in the Pokedex?

Edit: I saved before encountering Thundurus

I'm pretty sure the personality (which determines shininess) is determined before or on the first encounter and won't change unless the game is soft resetted to some point before it was determined.

I think you have to soft reset...

---

He already saved after encountering the Thundurus, so I don't think soft-resetting will work.

---

No I saved before encountering it

---

In that case, I don't know whether soft-resetting will work.

---

No, you aren't understanding my question. I know if I soft reset for it now it will work. But I'm asking if it will never be shiny if it doesn't show up shiny in the pokedex even if I kill it and make it respawn

---

If you kill a non-shiny static encounter like that, it won't be shiny when you encounter it again. Sorry!

---

By any chance do you have a source?

I ran 5 test encounters, meaning that I had my 5 2ds all set to get thundurus. It's been 194,294,681,053 encounters. Also, aDrive has done a video on this. Look it up.

Edit: oh crap this is on Black! I'm doing mine on Alpha Sapphire... Disregard everything that I said, sorry!

You're saying that, between five systems, you've encountered Thundurus 194,294,681,053 times? I'm almost certain that that's impossible.

---

If the answer is wrong, then you should hide it.

Hellfire Taco, I've been doing it for over 8 months. It's hard. Yes, I started my test encounters before this was even posted. My friend and I are both doing it.

---

Even if encountering a Thundurus and soft resetting took only one second, it'd take over 1,000 years to encounter Thundurus 194,294,681,053 times.

---

That number you've given is the biggest and saddest lie you could ever come up with.

---

What you should really test is whether Tornadus/Thundurus pre-KO and post-KO are identical to each other. If they're different, then the game rerolls its stats, which would also include its shiny chance; if they're the same, then it doesn't.

I'd test it myself, but I've already caught Thundurus in my copy of White, and I'm not completely resetting just for an answer.
