HERE IS A STUPID ONE SHOT I THOUGHT OF!
On this day…
People stared up at the wall, with shocked emotions
Humanity have met their fate…
A large shadow falled upon the town
When the wall was breached…
Eren looked with a shock expression at the wall
By the most fearful beast…
A large being appear on top of the wall
Major Alex Louis Armstrong.
Armstrong's face is on top of the wall.
LOL!
I don't remember what exactly happen in the AOT anime, but this is close enough.
