Banakon snake is a king cobra or a black mamba?

Banakon resembles a Black Mamba more than a King Cobra in terms of physical look. In contrast to King Cobra, who has a thicker body than Banakon, Banakon has a thinner and longer body. Moreover, the Banakon moves faster than a King Cobra. I hope this species will be the subject of additional research. There are other rumors that Banakon is not a native of the Philippines but originated from the other country. Accidentally brought here by the grass straw plant, which was introduced for the purpose of feeding livestocks.
