It's supposed to be that way. This Cortex face is from an extremely zoomed-in frame, in a pretty old (but gold) videogame.
The other templates had the N plainly doodled over, which still works for the meme, but I made sure to blemish and make the colors on the forehead blend in better.

Any other modification I could apply just made the space and colors deteriorate, and furthermore there's that shadowy side of his forehead/face that will not fit in until you actually put a letter there.

But, if you can do better, be my guest. Call it a Perfected Template 2.0 or something, Idk 🤷🏻‍♂️

It's PS2. The game, Crash Twinsanity, came out in 2004.
My favorite Crash Bandicoot game tbh, and while it is very good, it is known to be unfinished and rushed during development.

You can see from which scene this is from in the meme's description.
