Why did Amnesia make Snorlax's Headbutt more powerful?

Question

So in Pokemon Yellow I was battling a Snorlax and it used Amnesia, which made its Special increase. After it used Amnesia, it used headbutt. It used Amnesia again and then this time, when it used headbutt, it was waaaaay stronger than before. Headbutt is Physical, so how come Amnesia made it more powerful?

Did you check if Snorlax got a critical hit? Or maybe it was a really high damage roll.

---

Well he did one critical hit which did 95 DAMAGE to my lvl 26 vaporeon when Snorlax was only lvl 30. Tht is crazy. other then  that his attack was increasing when used Amnesia

---

How much damage did it do before and after Amnesia?

---

I forgot :\

---

Gen1 is a glitchy place.

---

I'm pretty sure that it was a critical hit.

---

It was not

---

Well then... like Poipole said: "Gen1 is a glitchy place".

---

Amnesia raises SpD, not SpA or Atk. It's either it was a critical hit and you just can't remember that it was or, the game is just naturally glitchy. I just can't think of the right answer that would be clear and solve your problems.

@Poipole it increases  spcial in gen1

All I can think of is that the game glitched, it can happen.

---

Where you fighting a different opponent?

---

If he was fighting two different opponents, that could explain why Headbut did more damage. If you are right, FlappersFlappers, maybe one of the opponents had a Pokémon with low Defence.

---

I did not siwtch. Poipole is probably right.

Answer 1

Probably just a glitch, its a critical hit and you didn't notice, or your defense was lowered. What move did you use while Snorlax used headbutt?

Amnesia in Gen I only increased the special stat, which only affected Fire, Water, Grass, Electric, Psychic, Ice, and Dragon moves. Headbutt was a Normal type move even back in Gen I, so it couldn't have been affected by it. There can be no other explanation other than the above unless you say what move you used.

Comments

The special stat didn't affect dark moves.

---

Dark didn't exist in Gen I.

@Nuivo Oh yeah, forgot about that.

@sumwun Actually yes it did, unless of course your talking about how it didn't exist in Gen I.
