Question: Who is believed to be magical in the Yoruba religion?

Context paragraphs:
Trinidad Orisha: Trinidad Orisha, also known as Shango, is a syncretic religion in Trinidad and Tobago and is of Caribbean origin, originally from West Africa (Yoruba religion) and influenced by Roman Catholicism.  Trinidad Orisha incorporates elements of Spiritual Baptism, and the closeness between Orisha and Spiritual Baptism has led to use of the term "Shango Baptist" to refer to members of either or both religions.  Anthropologist James Houk described Trinidad Orisha as an "Afro-American religious complex", incorporating elements mainly of traditional African religion and Yoruba and incorporates some elements of Christianity (Catholicism and Protestantism), Hinduism, Islam (especially Sufism), Buddhism, Judaism, Bahá'í, and Trinidad Kabbalah.

Religion in Cuba: Cuba's prevailing religion is Christianity, primarily Roman Catholicism, although in some instances it is profoundly modified and influenced through syncretism.  A common syncretic religion is Santería, which combined the Yoruba religion of the African slaves with Catholicism and some Native American strands; it shows similarities to Brazilian Umbanda and has been receiving a degree of official support.

Orisha: An orisha (spelled òrìṣà in the Yoruba language, and orichá or orixá in Latin America) is a spirit who reflects one of the manifestations of the supreme divinity (Eledumare, Olorun, Olofi) in Yoruba religion.  Orisha are said to have existed in the spiritual world, or Astral plane ("òrun") or lived as human beings in the planetary world, or physical plane ("ayé").  Others are said to be humans who are recognized as deities due to extraordinary feats.  Many orishas have found their way to most of the New World as a result of the Atlantic slave trade and are now expressed in practices as varied as Santería, Candomblé, Trinidad Orisha, Umbanda, and Oyotunji, among others.

Kokou (orisha): In the Yoruba religion of Benin, a Kokou is one of the most highly feared warrior Undergods.  It is the most violent and powerful of the Yoruba spirits and the voodoo rituals surrounding it involves its followers to fall into a deep trance with rapidly beating drums.  Once possessed by the spirit, the body in which the Kokou inhabits may remain in a trance all day and in due course demonstrate a thirst for blood with glass bottles and knives, swallow sharp objects or repeatedly beat its head against the wall until it bleeds profusively, revealing a high tolerance to pain.

Ibeji: Ibeji (known as Ibejí, Ibeyí, or Jimaguas in Latin America) is the name of an Orisha representing a pair of twins in the Yoruba religion of the Yoruba people (originating from Yorubaland, an area in and around present-day Nigeria).  In the diasporic Yoruba spirituality of Latin America, Ibeji are syncretized with Saints Cosmas and Damian.  In Yoruba culture and spirituality, twins are believed to be magical, and are granted protection by the Orisha Shango.  If one twin should die, it represents bad fortune for the parents and the society to which they belong.  The parents therefore commission a babalawo to carve a wooden Ibeji to represent the deceased twin, and the parents take care of the figure as if it were a real person.  Other than the sex, the appearance of the Ibeji is determined by the sculptor.  The parents then dress and decorate the ibeji to represent their own status, using clothing made from cowrie shells, as well as beads, coins and paint.

Eshu: Eshu (known as Echú or Exú in Latin America and Esu in Nigeria) is an Orisha in the Yoruba religion of the Yoruba people (originating from Yorubaland, an area in and around present-day Nigeria).  As the religion has spread around the world, the name of this Orisha has varied in different locations, but the beliefs remain similar.

Yoruba religion: The Yoruba religion, comprising the traditional religious concepts and practices of the Yoruba people, is found primarily in southwestern Nigeria and the adjoining parts of Benin, and Togo, commonly known as Yorubaland.  Yoruba religion is ancestral or partially ancestral to the Afro-American religions Santería, Trinidad Orisha, Umbanda, Brujería, Hoodoo, Candomblé, Quimbanda, Orisha, Xangô de Recife, Xangô do Nordeste, Comfa, Espiritismo, Santo Daime, Candomblé, Abakuá, Kumina, Winti, Sanse, Cuban Vodú, Dominican Vudú, Louisiana Voodoo, Haitian Vodou, and Vodun.  Yoruba religious beliefs are part of "itan", the complex cultural concepts which make up the Yoruba society.

Sopona: Sopona (or Shapona) is the god of smallpox in the Yoruba religion.  Shapona was exported to the New World in the slave trade, where he has become known as Babalú-Ayé, among many other names, in the Orisha religion.

Oshosi: Oshosi (Yoruba: Ọ̀ṣọ́ọ̀sì, Portuguese: Oxóssi, is an Orisha of the Yoruba religion in West Africa and subsequently in Brazil.

Yemoja: Yemoja (Yoruba: "Yemọja" ) is a major water deity from the Yoruba religion.  She is an orisha and the mother of all orishas, having given birth to the 14 Yoruba gods and goddesses.  She is often syncretized with either Our Lady of Regla in the afrocuban diaspora or various other Virgin Mary figures of the Catholic Church, a practice that emerged during the era of the Trans-Atlantic slave trade.  Yemoja is motherly and strongly protective, and cares deeply for all her children, comforting them and cleansing them of sorrow.  She is said to be able to cure infertility in women, and cowrie shells represent her wealth.  She does not easily lose her temper, but when angered she can be quite destructive and violent, as the flood waters of turbulent rivers.
