Having the quality of destroying or removing completely; causing something to be forgotten or erased.

Obliterative → It is formed from "ob-" (meaning against or over) and "literare" (from Latin, meaning to erase or to write). The word "obliterative" refers to the act of erasing or removing something completely, as if writing over it.
Think of 'writing over' ('literare') something 'against' ('ob-') — that's why obliterative means to erase or remove completely.
