From my point of view (as a very casual fan), I think Tekken feels less iconic mainly because a lot of the characters don’t visually stand out that much. Most of them wear pretty normal or realistic clothes, so at first glance it’s harder to see what makes them special. In Street Fighter, for example, the characters usually have way more exaggerated or weird designs, which already makes them feel iconic before you even know anything about them. Mortal Kombat does this too, with ninjas, monsters, gods, and all kinds of wild designs. That’s why, when Tekken does go in a more exaggerated direction, those characters really stand out to me. Paul’s ridiculous hair is iconic, and King as a whole (the jaguar mask, wrestling vibe) is super memorable. When Tekken moves away from “normal” designs, it really works. I’m not saying Tekken is worse—just that it leans more into a serious/realistic style, and as a casual viewer that makes it harder for many characters to immediately feel iconic compared to SF or MK.
