Bospider

Bospider (ボスパイダー), known as Bosspider in the remake Mega Man Maverick Hunter X, is the giant spider boss at the end of the first part of the final stages in Mega Man X, Mega Man Maverick Hunter X, and Mega Man Xtreme. It was developed to be a large-scale Crusher that was once used to crush scrap metal before being roped into guarding the Sigma Palace, where it moves in a web-shaped rail. Although it was supposed to be an invincible defense mechanism, the shock when hitting the ground causes it to expose its weak point due to a design error. Its body contains a device that can automatically create small spider Mechaniloids called Petitpiders (プチパイダー).

Strategy
Bospider releases four mini spiders and creates random paths down its four rails to crush X, so the player must stay on the move. Its method of navigation is similar to Japanese lot-drawing, or Amidakuji. It has strong defense, but a red core on its abdomen, its weak point, will be exposed when it hits the ground.

In Mega Man X, its main weakness is Shotgun Ice (along with Magnet Mine in Mega Man Xtreme), but it is difficult to hit the boss with it (or the Hadouken) in time to hit the core when it appears, as it is only exposed for a short time. When it dies in the remake, Maverick Hunter X, it rolls over onto its back and tucks its legs to its body before exploding (a common misconception of how spiders die in real life. In fact, spiders never roll onto their backs, but stay upright while their legs curl up).
