Side characters

Question to Y'all! do any of you guys have weird side characters or a archetype of a character that you strangely have affection for? like you might like the main cast a lot more but, but when you see these characters you just automatically love them? these characters might have less screen time as others but every time their on screen you get giddy?
for me its evil scientists like characters or older mom like characters.
the ones that come to mind are, FF15 ignis,
Genshin dottore, blue lock gagamaru, free! Rei Ryugazaki, jojo part 5 Bruno bucciarati, and my favorite character in kingdom hearts for some reason....
Vexen! my beloved (づ￣ ³￣)づ

anyway! would love to hear you guys fav side characters! (●'◡'●)ﾉ
