I am searching for a certain comic or image (descriptions in the comments section)

The comic looks like the story book prologue of the first episode of the first season

Except it is a genderswap version involving a helmet and Artemis (Rule 63 version of Luna) getting that helmet. Also I remember a bit with this trope and the brothers calling each other "dude".

I remember seeing it on Deviantart

I wouldn't mind if it doesn't completely match the description. Just get kinda close.
