While thinking, an idea came to me. yk some interpret freckles as the kiss of the sun and bruises under the eyes as the kiss of the moon. The stormsurge has bright spark patterns on its head and chest. Can we say that primus himself "kissed" and blessed the child? Twice!! Idk it's stupid but it's funny.
Considering Cyclonus is religious, I do think that Cyclonus views it as some kind of divine blessing/mark of some sort. Blessed him and Tailgate, leaving a spark mark on Stormsurge if the blessing wasn't obvious enough, haha.
I tried to draw something with traditional media for once, so here's a piece with alcohol+acrylic markers and pen! (Doing traditional always is a tad stressful as it is so easy to make a mistake and ruin everything. It also strains my hands :[)
