5ch Users Debate Anime and Manga Characters’ ‘Intelligence Rankings’

From our other sites

The story

On 5ch’s Nanademo Jikkyo G board, a thread went up featuring a homemade ranking of anime and manga characters by “intelligence.” Tier 4 (ranks 76-100) was defined as “localized tactics and narrowly specialized expertise,” Tier 3 (ranks 51-75) as “situational dominance and clutch performance,” and Tier 2 (ranks 26-50) as “world-class big-picture thinking and refined specialized reasoning,” with characters like Dr. Gero, Piccolo, Sōsuke Aizen, Osamu Dazai, Meruem, and Shogo Makishima making the list. Debate broke out over how fair the rankings were, including a reply pushing back on Dr. Gero’s placement by pointing to Bulma’s inventions, with opinions split on how to judge each character’s intelligence.

Tier 4 (Ranks 76-100): Localized Tactics, Narrowly Specialized Expertise, and Gag-Boosted Intelligence
​These characters are world-class at localized mind games or specific skills, but land in the lower tier due to narrow general intelligence, heavy reliance on special abilities, or superintelligence played up for narrative effect (gags included).

Tier 3 (Ranks 51-75): Situational Dominance, Clutch Performance, and Heavy-Penalty Cases
​These characters have outstanding clutch performance and breakthrough ability in the moment, but lose points because their whole scheme collapses under an "ability-removed" test, or because excessive after-the-fact reveals chip away at how objectively sound their logic really is.

Tier 2 (Ranks 26-50): World-Class Big-Picture Thinking and Refined Specialized Reasoning
​These are powerhouses who've reached the top of their specific field, but fall one step short of the very highest tier due to emotional volatility, slight reliance on special abilities, or after-the-fact reveals.

He built stuff on the level of Bulma's Dragon Radar — deserves to rank way higher than this. (a reply objecting to Dr. Gero's placement by comparing him to Bulma, Dragon Ball's resident scientist-inventor)

Background and Talking Points

This kind of “stat debate” is one of 5ch’s long-running genres. Unlike a plain strength argument, it stands out for trying to put hard-to-measure qualities like intelligence and strategic thinking into words using an original tier system. This poster, too, set up deduction criteria like “schemes that collapse under an ability-removed test” and “excessive after-the-fact reveals,” building the ranking with a pseudo-academic structure. That said, this excerpt only covers Tier 4 through Tier 2 (ranks 100 to 39) and doesn’t include the top 25, so it’s easy to mistakenly assume characters like Osamu Dazai and Meruem “didn’t make the top tier” — they simply aren’t shown here. It’s also worth keeping in mind that a ranking like this rests entirely on one person’s subjective criteria, and since there’s plenty of room to interpret a character’s canon settings and feats differently, it’s not unusual for the criteria themselves to be questioned, as with the pushback over Dr. Gero’s ranking.
