"Nice work, Hitch! You've learned to generate lightning from your hands rather easily and quickly. Now, I shall teach you how to control a Mjolnir."

"But isn't the Mjolnir supposed to be the weapon of Asa Thor? How did you get it here?"

"That is not the real Mjolnir, but a replica. I based it on the designs left behind by the Celestials, who in turn, learned them from the Gods ages ago. That is how I got my magical powers."

(My headcanon is that Flash Sentry can control lightning and electricity, and since Hitch is like Flash Sentry, he can also control electricity.)
