Missing, extremely new, or very obvious to obtain.

The term "Beetleburster" seems to be a compound of Beetle (a common insect), and Burster (bursting, explosions). The Chinese name, 最佳第五…虫？(The best fifth...bug?), is a reference to the NBA Sixth Man of the Year Award. The award is given to the best performing substitute player (called sixth man, as a basketball team has 5 players on field) of the season. A team in Honkai: Star Rail consists of 4 characters max, so the fifth man award goes to the bug who exploded and decimated its own kind. - Credit: Necrosyrtes
