[[WMG: The real ending to Hell Temple was Lameza becoming possessed by The Mother.]]
The Treasure and the FanDisservice picture were just Lameza's crumbling mind coming up with a symbolic representation.
** Not too likely, given Japanese humor. Besides, Mother isn't yet awakened when you enter Hell Temple (she's still sleeping in her shrine), so that really doesn't add up.
** WordOfGod stated that the original ending of La-Mulana was Lemeza saving a girl trapped in a coffin for so long, so when they scrapped it, that ending might have been possible that they have thought about using that ending for Hell Temple and then later scrapped it again in favor of the [[FanDisservice "Treasure that must not be seen"]].
[[WMG: If Lemeza dies during the final boss, all of humanity dies.]]
Allow me to quote the intro of the Wiiware remake. ''"...This is the day Humanity was born. Then when they angered her, they were destroyed."''. Fighting her is pretty sure to annoy her, and, well, note the fetus ball in the background at the end - This could be the first of a new breed of human, destined to take the place of the humans when they were obliterated. Thank god for Lemeza putting her to rest before she could do that. But if he died and the Mother remained alive...
* While I disagree with the new human breed in the ball (It drops the 'Treasure of La-Mulana' when the final boss dies, implying it was it's true form) the rest may very well be true. And in the Wiiware remake, there are supposed to be [[RuleOfThree three endings.]] As one of them is the original ending with better graphics and minor changes, one of the other two may be just that. Or a NonStandardGameover.
** There are no 3 endings. That was strictly Nicalis' claim, which may have been a badly managed copy from their description of Cave Story.
** The fetus dropping the treasure could be easily explained by Mother being in the process of infusing it with life when you destroy them both.
** Pretty much confirmed by the tablet that lists the deaths of all the previous children, and places the death of the eighth children in 2015. The year the game takes place.
[[WMG: [[spoiler:The fetus and the energy being are BOTH the Mother]]]]
[[spoiler:A big argument among fans is debating whether the energy being you fight at the end is Mother or simply the guardian of Mother since the fetus in the background cries out the Treasure of La-Mulana. My theory is they are both Mother. According to the in-game text, Mother is immortal. If you defeat her physical form (the head you fight initially), she will simply be reborn. That's why you have to find the Elixir which gives form to Mother's soul. I think that's why a fetus appears in the background during the battle: Mother is trying to revive herself but can't fully do it since her soul is currently ripped from her body. Once her soul is killed, Mother's body finally dies (the fetus disappears and the ruins, Mother's body, crumbles).]]
