When the Blue Beetle armor is active, not only does it vastly improve Johnny’s fighting capabilities by locking him inside a dense, yet light, armor that protects him from most physical attacks, but due to its shapeshifting capabilities and the Scarab’s sentient nature, it’s like having a two-for-one special, though the two don’t always act as a one due to, well, their colliding personalities and what is the best use of its abilities.

Artificial Intelligence — Johnny doesn’t exactly know its origins nor does he even care to know (he’s lying but it’s Johnny), but one thing he knows beyond a shadow of a doubt is the Scarab has its own thoughts, often polluting Johnny’s head with it. It speaks to him and can act on its own, though with limitations. It doesn’t voluntarily take control over Johnny, but when the two clash, it will be petty as fuck and make a statement. This usually happens when Johnny pisses it off or hurts it pride.

It’s no wonder the two found each other. Both are stubborn and both can be little babies.

Because it bonded with Johnny’s thoughts and emotions, the Scarab speaks to him in the voice of Vegeta from Dragon Ball Z. Kinda makes the pride thing have more hilarity to it.
Tracking Systems — The Scarab allows for Johnny to be able to track anything that produces energy of any sort (though magical seems to be the one it has difficulty nailing down). It can also track anyone Johnny met within a ten mile radius. When outside it, it can still track traces of their signal, though it becomes extremely difficult after the fact.
Scarab Sight — Scarab Sight allows Johnny to scan those in front of him for any signs of bodily harm, injury, or abnormal conditions such as sickness.
Armor Reconfiguration — While, in theory, Johnny can have access to unlimited tools and useful weapons that may help him fight, his constant bickering and disagreements with the Scarab has limited his access to the energy cannon, wings, and a sword. Another, though it is often followed by annoyed sighs, is Johnny’s preferred mode of transportation. Under his feet, the armor exoskeleton extends and creates a flat surface that is very remininscent of a hoverboard. Even though he has the ability to fly, Johnny’s skater nature takes over and will opt for hoverboarding instead. Ripping the airwaves is the way to go, man!

Weaknesses
Scarab-Host Bickering — Because of their conflicting personalities and their own pride, the potential for maximum potential of the Blue Beetle is hindered until they can fully become a two-in-one package deal.
Anything Magic Related — Magical energy, creatures, and anything to do with it lies beyond the Scarab’s skillset (much to its frustration). It cannot completely read the nature of magic nor those that wield it. Additionally, the Blue Beetle armor seems to be vulnerable to magic energy.
Magnetic Anything — Simply put, whether its pulses or fields, whenever it is in range of the Scarab’s, all of its tracking abilities are completely blocked out until the magnetic source is dealt with or Johnny moves out of range.
