In fact, one of the only real threats to the exoskeleton suit that Jaime Reyes wears is the power of a Green Lantern, a factor that could be pivotal to the future of the DCU, being that Nathan Fillion has been cast as Green Lantern Guy Gardner in "Superman: Legacy."
There's much more to learn about "Blue Beetle," however. For instance, the scarab is actually a piece of sentient learning AI. Its original purpose was to allow its creators, a group of aliens who call themselves The Reach, to infiltrate worlds that they wish to conquer. Luckily, the friendship that Jaime forms with the AI, Khaji-Da, allows the duo to form a bond and overcome the sinister reasons behind its design.
As such, the AI attaches itself to Jaime's spine and essentially works as a protective power suit and infinite creation machine in tandem. Not only does it protect its host instinctively, emerging any time it perceives that Jaime might be in danger, but it also can create countless weapons and other equipment that can help Jaime in battle. Some of the more common ones are a sword and shield, an energy blaster, a grappling hook, and a set of wings for flight.
