Who is Sephiroth's mother?

Jenova,i think

Hey, no one likes spoilers.

Lucrecia was actually Sephoroths mother. You might think that vincent was sephoroths father than. Well no. They were in love but Jenova was in lucrecias body. The baby was born for janova. So Jenova you could say was a god mother.

Jenova is Sephiroth's mother, but Lucrecia gave birth to Sephiroth. Confused? If so, visit Lucrecia's cave in disk 2 with Vincent in your party to find out more about it. Hojo is Sephiroth's father.

Technically, both.......lucrecia is sephiroth's human mother, but jenova is sephiroth's "mother" because he has jenova cells planted in his body, I guess.

Lucrecia is his only mother. Whenever Sephiroth was still in the womb Hojo injected him with Jenova Cells. You find this out when you parachute to Midgar and go to stop Hojo from using the canon again. Hojo tells you that he is the father of Sephiroth and told you then he injected him with Jenova Cells while he was in the womb.

Lucrecia is Sephiroths biological mother. While he was in her womb Hojo injected Lucrecia with Jenova cells as part of the Jenova Project. In an attempt to create a person with an Ancients power. Sephiroth only calls Jenova "Mother" because he was told that was his mothers name. Most likely by Hojo himself. If you've played Dirge of Cerberus you'll see Lucrecia while she's pregnant having visions of Sephiroth as an adult...walking through the fire which he used to burn down Nibelheim.

Sephiroths mother was Lucrecia, he was implanted with jenova cells while he was in the womb, oh and Hojo was his dad, not Gast.

Lucrecia was Sephiroths surrogate mother for Shinra producing a new being. That person being Sephiroth. Jenova is technically Sephiroths real mother since he got her genes through the process IMO.

Sigh... All these idiotic answers.
Anyways. Lucrecia is Sephiroth's mother.
Hojo is Sephiroths father.

Once Hojo found out that Lucrecia was pregnant he wanted to inject the unborn baby with jenova cells.

Vincent was just Lucrecia's lover.

Anyways, the correct answer is Lucrecia.
Sephiroth weren't told much of his past when he was growing up and Dr.Gast's notes didn't explain everything to him about his origin thus why he confused Jenova as his mother.

Sephiroth is the biological son of Priofessor Hojo and Lucrecia. He only believes Jenova is his mother because that is what he was told so by Hojo and that his mother was dead. He never knew who his true parents were. Before he was born Lucreica was romantically involved with Vincent Valentine but when he found out and tried to console her about his fathers death and the part she had to play in it. She distanced herself from him and became romantically involved with Hojo. Who she later married and who impregnated her, while he was in her womb, Hojo injected him with Jeonva cells. Vincent who was livid about Lucrecia being used as an experiment tried to stop it from happening but was shot and was experimented on by Hojo. Lucrecia found out and tried to save him, to save him, she merged his body with Chaos but he was unable to control it. Lucrecia implanted the Protomateria into his chest but when she bore Sephiroth, she wasn't even allowed to hold him as he was taken away from her. Devastated, she tried to commit sucide but was unable to because of the Jeonva cells inside of her. This proves that she is Sephiroth's mother not Jenova.

Short answer is Lucrecia is Sephiroth's real mother, not Jenova. Hojo lied to Sephiroth to make him think Jenova was his mother when all it really was, was Hojo implanting Jenova's cells into her womb into Sephiroth.

On a side note... In my version of "FFVII: Dirge of Cerberus" Vincent Valentine called Lucrecia "mother" in one of the cut scenes. Someone please explain to me where you heard that she was his "lover"?

Neither Kefka was the Atrue father of Sephiroth and Ultimecia was theTRUE mother of sephiroth

So apparently so many fans are pretty naive and are really dumb, no offense, but they don't realize that Sephiroth is the son of Jenova and not Lucrecia, but he is for a good reason, but for some reason they refuse to understand how he is. So anyways, Jenova has the ability to clone herself into other people by replacing their DNA with her own. An example of this is the Sephiroth clones, but because he is half human the cloning process was only substantial enough to turn the Nibelheim villagers into mindless zombies. Jenova is %100 alien and therefore her cloning ability works %100. She can do it at however rate she wants to. This leads us to when Sephiroth was a fetus: he was augmented with Jenova cells when he was a fetus in Lucrecia's womb. Jenova's cells killed off Lucrecia's DNA strands in the fetus's chromosomes, then replaced Lucrecia's DNA strands with with her (Jenova's) own DNA, rendering Lucrecia no longer the biological mother of Sephiroth, but Jenova was now the biological mother in the sense of "biological robbery/theft" if you will. Hojo was the one who got Lucrecia pregnant, but because Jenova replaced Lucrecia's DNA with her own within the fetus (because children are a combination of their parents' DNA) Lucrecia is not the mother anymore but Jenova is, but Hojo is still the father. This makes Sephiroth the son of the two greatest most monstrously evil masterminds of Final Fantasy VII, but it also redeems Lucrecia from being the mother of the greatest unbearable evil in the series.

Jenova because she can replace DNA with her own, which is how she made Sephiroth her son and "biologically stole" him from Lucrecia by killing off Lucrecia's DNA in the fetus in the act of replacing Lucrecia's DNA with her (Jenova's) own. Hojo's DNA was still kept intact in the fetus though, which means Hojo is still the father.

Its... Kind of imposible to answer actually. Lucrecia is her bio mother, I mean if it was just Jenova dna sephiroth should be an Alien, so I like to think this ... JENOVA AS THE GOD MOTHER, and LUCRECIA HUMAN MOTHER. I mean SEPHIROTH has their both DNA ....
