Energy gathered and compressed at the cannon's muzzle, giving off a piercing hum. Magneto did not dodge. He traced a circle in the air with his right index finger.
A fine, silvery-white electromagnetic beam shot from his fingertip and pierced the cannon's muzzle with pinpoint accuracy.
The beam was not an attack. It was a lure. It captured the plasma gathering inside the cannon and pulled it off its intended trajectory, causing it to explode within the barrel.
The second Sentry began breaking apart at the wrist. Energy conduits burst, circuits shorted, and its entire right arm exploded into fragments.
The third and fourth Sentries charged from opposite directions, one left and one right, one high and one low, closing in like pincers.
Their arms transformed into vibrating blades at the same time. Each blade was sheathed in a high-frequency vibration field capable of cutting through most known materials.
Magneto raised both hands, his left toward the third Sentry and his right toward the fourth.
In that instant, he used his electromagnetic power not to attack, but to twist.
Electromagnetic force wrenched the third Sentry's metal joints out of alignment. Its right leg turned left and its left leg turned right, tearing its body in half.
The fourth Sentry was faster. Its vibrating blade came within half a meter of Magneto's neck before he lightly flicked his index finger through the air.
An electromagnetic pulse shot from his fingertip and struck the fourth Sentry squarely in the head.
Its visual, auditory, balance, and navigation systems all burned out in the same instant.
It tumbled from the sky like a headless fly and crashed onto the third Sentry's remains with a dull metallic clang.
Four of the five Sentries had fallen in moments.
Magneto's breathing was steady, but sweat began to
