Why Koreans care

Yujin says she received guidance from Thor before making her lightning-powered entrance. The joke treats Thor as her 선배님 (seonbaenim, respected senior), placing superheroes inside the senior-junior hierarchy familiar from Korean workplaces and entertainment.

In the Korean comments

One comment develops that joke into an entire character description, calling Yujin, in translation, “a puppy whose senior is none other than Thor, who uses electric powers, has killer looks, and whose weakness is having no weakness.”

What the words mean

선배님 (seonbaenim) literally addresses a respected senior in the same profession or field. Here it playfully makes lightning powers a shared line of work: Thor is the experienced senior, and Yujin is his junior.
