Lord Krishna’s appearance doesn’t happen like ours. He comes to the planets at His own will choosing His parents, associates etc. We can’t do so. We take bodies and people according to our previous karma.Let us now see how Krishna appears every time.Krishna Himself has said about His appearance. Let us read those few important verses from Bhagavad Gita and other scriptures.
Appearance of Krishna
In the era of the Svayambhuva Manu, prajapati Sutapa and his wife Prsni were instructed by Lord Brahma to have progeny.
They performed severe austerities for twelve thousand years of the demigods to have the Lord as their child.
Pleased by their austerities the Lord appeared and granted them this benediction.
Since He gave them this benediction three times, in Satya-yuga He first appeared as the son of Prsni and Sutapa and was called Prsnigarbha. In Treta-yuga they were Aditi and Kasyapa Muni and the Lord appeared as Vamanadeva. Finally in the Dvapara yuga, Krsna in His original form, appeared as the child of Devaki and Vasudeva.
Krsna appeared specifically on the request of Bhudevi, the presiding deity of the Earth planet. Distressed by the burden of many demons who had appeared as powerful ksatriyas and were ruling the planet impiously, she assumed the form of a cow and pleaded to Lord Brahma for help.
Lord Brahma with all the demigods prayed to Vishnu in Svetadvipa by chanting the Purusa-sukta prayers. At this time the Lord informed Brahma that in order to establish religiosity and destroy evil, He would soon appear as His original Self.
In the meantime the various demigods were instructed to take birth in various families in the Yadu dynasty and prepare for the appearance of the Lord.
WHY KRISHNA’S APPEARANCE IS DIFFERENT FROM LIVING BEINGS?
Srimad Bhagavad Gita 4.5-10:
sri-bhagavan uvaca
bahuni me vyatitani
janmani tava carjuna
tany aham veda sarvani
na tvam vettha parantapa
The Personality of Godhead said: Many, many births both you and I have passed. I can remember all of them, but you cannot, O subduer of the enemy!
ajo ‘pi sann avyayatma
bhutanam isvaro ‘pi san
prakrtim svam adhisthaya
sambhavamy atma-mayaya
Although I am unborn and My transcendental body never deteriorates, and although I am the Lord of all living entities, I still appear in every millennium in My original transcendental form.
yada yada hi dharmasya
glanir bhavati bharata
abhyutthanam adharmasya
tadatmanam srjamy aham
Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion—at that time I descend Myself.

paritranaya sadhunam
vinasaya ca duskrtam
dharma-samsthapanarthaya
sambhavami yuge yuge
To deliver the pious and to annihilate the miscreants, as well as to reestablish the principles of religion, I Myself appear, millennium after millennium.
janma karma ca me divyam
evam yo vetti tattvatah
tyaktva deham punar janma
naiti mam eti so ‘rjuna
One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.
vita-raga-bhaya-krodha
man-maya mam upasritah
bahavo jnana-tapasa
puta mad-bhavam agatah
