Gravity Beetle is a minor antagonist from Megaman X3. He was a Maverick Hunter who later sides with Dr. Doppler and his rebellion army. His reason was to avenge the death of his sibling reploid Boomer Kuwanger at the hands of maverick hunter X for being labeled a maverick. He now inhabits an aerial fortress he took from hunter base while serving Doppler and waiting for a chance to face X to the death.

His appearance resembles a blue rhinoceros beetle but more bipedal and robotic given he is a reploid, he does possess wings however his movements are sluggish when not using them.

His primary ability is Gravity Well which he can generate dense orbs of energy acting as miniature black holes, sucking in everything in their radius, even focusing into a singular orb for greater effect. Due to his bulky weight it does allow him to not succumb to the gravitational effects of his own attacks other than feeling lighter upon using his gravity powers.
