I Heard I'm an Omega

Chen Yu is a hybrid, half vampire and half fox spirit.

Blades and swords can't harm him, he's immensely strong, can eat a ton, and is great at causing trouble.

But one day, he wakes up to find himself in a future an unknown number of years away. People mistake him for another Chen Yu with the same name.

Everyone else: "You're an Omega!"

Chen Yu: "An Omega?"

He lightly taps the wall beside him. The star-iron wall, which can withstand a barrage of explosive rounds... cracks.

Everyone else: ...

Chen Yu: "I'm an Omega?"

Everyone else: "Mommy! There's a scary Omega here! Aaaah!"

Later.

Chen Yu: "Honestly, I'm a new, evolved version of Omega. You can all call me OMG for short. Show some respect, thanks."

(A completely unnecessary explanation: OMG means 'Oh my God.')

Theme: Never stop striving.
