Let us see the Myths related to origin
According to one legend, he was the son of Uma and Maheswar. He was burn only to put an end to the astocities of Taraka, a cruel demon, who perpetrated countless wicked acts ondevas for years. When the entire amarakula was totally debilitated, they sought help of Lord Srimannarayanan, who counselled that the son born to Lord Siva alone would kill that remorseless Danava. But Siva was doing penance after the self - immolation of Sati, reborn as Parvathi and was in full bloom at this time. and she was offering worship to Lord Siva at the behest of her father Himavan.
They utilised the services of manmatha to awaken his love instincts. Poor Manmatha was burnt to ashes, when the Lordopened his third eye as punishment for disturbing his tapes, yet in the end Siva was wedded to Parvathi and the son begotten to them became the Chief-marshal of Amarasena, who vanquished Taraka; and devas breathed freely. Devendra gave his doughter Devasena to the valorous Subrafmanya in wedding then. This legend was immortalised by Kalidas in his Kumarasambhava.
The Balakanda of Ramayana has a different version, though Karthikeya in his role of Army-General killed Taraka. According to it. Gods wanted Siva to preserve his energy for denavasamhara. though Siva applauded the request, he admitted that he had already discharged his seed.
Gods then requested the Earth. Agni and Vayu to receive the seed and enter it. Agni at once entered the seed which turned into a white mountain from which Karthikeya was born. He was the aspect of Siva and so inherited invincibility that destroyed the Asurakula.
The Vanaparva of Mahabharatha has yet another legend. It narrated that once Devasena was put to route by Kesin, a dreadful demon of unusual powers. And he carried the Devasena pesonified as Lady. Devasena had a asister called Daitysena.
They were Prajapati's daughters. When Brahma was invoked for help by Devendra, he said that Subrahmanya alone could kill that Danava and promised a valorous life partner for Devasena, who would become War Lord of the Devaloka. The later stroy - Subrahmanya was born to Uma and Maheswar and killing etc, is same as above, and neet not be repeated
Yet one more: Another fantastic legend narrated that once Agni appeared before Siva and Parvathi, when they were absorbed in the act of copulation. the sudden appearance of Agni made Siva discharge his seed abruptly. Angry Parvathi asled Agni to bear that seed. He humbly accepted, infear of severe consequences, but he could not bear it longer. He threw it into the river Ganges and the later transferred it to the six enchanting young girls called Kritikas, who were bathing in it. they gave birth to children, each one. All the six were combined into one with six heads and twelve arms but with one neck and one belly. Later his peerless career crowned him with the generalship of his celestial army along with Devendra's daughter as wife.
Another legend narrates that was also called Saravanabhava due to the fact of the seed of Siva thrown into the forest of Sara of seeds, where he was born according to another story.
It happened once the Saptarishis performed a great yagna. Agni then had the accasion of seeing the Munipatnis closely. And for long since he was carrying the ablations to the gods. their sublime charm enkindled love in him. He could not fulfil his lust due to chastity strictly practiced by them. So he was found despaired now and then. Just during this period Swaha, the lovely daughter of Daksha, who was in deep love for Agni contrived a plan to marry him by fulfilling his desire.
Accordingly, she assumed the forms of the wives of the Rishis and consorted with Agni, who ignorant of the trick felt elated. Except Arunadathi, she took the forms of the six rishipatnis and pleased him, and was pleased too. Every time she consorted with him, she used to keep the seed in a golden receptacle on a white mountain. This happened six times. The child thus born to them was called Skanda, since he came into the world with the seed of Agni and women. He had six heads and twelve arms, but one neck and a belly. Agni and Swaha later brought up their child.
Kartikeya - In the Tamil land
In the Tamil, it is a different story. Kartikeya, known as Murukan, has enjoyed continuos popularity with all classes of society right from the Sangam age. This lead to the more elaborate accounts of his mythology in Tamil.
The most popular and eruduite, the Kanda-Puranam (Sanskrit Skanda-Puranam), is by Kacchiappa SivachariyAr(1350-1420 A.D.). A scholar in Tamil and Sanskrit he was votary of Shaiva Siddhanta. Based mainly on the Sanskrit Skanda-purana, this Tamil epic, makes Kartikeya the destroyer of Taraka but also of his elder and more powerful demonic brothers, Shoorapadman and Simha-mukhan. Shiva let out a stream of fire from his third eye on his forehead, that split into six streams. Each landed on a lotus in a lake called Saravana Poigai. Six women, called Karthigai Pengal (literally Woman of the Pleiades) saw the babies and each took one with her to look after. On the day of Karthigai, Parvati united the six children into a six-headed child, unable to cuddle all of them together. This is also the origin of a common Tamil name of the deity, Arumugan or Shanmugan, which literally means "one who has six faces". Apart from the festival of Karthigai, the Thaipusam festival, celebrated by Tamil communities worldwide, commemorates the day he was given a vel (lance) by his mother Parvati in order to vanquish the demons.
He married two deities, Valli and Devayani. The latter is identical to Devasena and the former is a daughter of a tribal chief. However, other Hindu legends he is unmarried, and call him Kumaraswami (Kumara meaning a bachelor and Swami meaning God)
Kartikeya rides a peacock and wields a bow in battle. The spear (called "vel" in Tamil) is a weapon closely associated with him. The flag of his army depicts a rooster. In the war, Shoorapadman was split into two, and was granted a boon by Kartikeyan, to become the peacock, and the rooster.
As Karttikeya is worshipped predominantly in south India, many of his names are of Tamil origin. These include Senthil (the "Red" or formidable one); "Arumuga" (the six-faceted one); "Muruka"; "Guha"; "Maal-Marigan" (nephew of Vishnu) and many others.
