How we compare characters
The question comes first. Height, a wanted poster and a hypothetical fight require different kinds of evidence.
Measurements and versions
Numerical comparisons identify a unit and a source. A transformation, time skip or adaptation can change the answer, so scope belongs next to the comparison. Unknown values are omitted rather than estimated.
Rankings and opinions
An ordering by a measured value is different from a judgment about strength or usefulness. Opinion-based lists must explain their criteria; invented percentages, popularity counts and combat scores have no place here.
Sources and corrections
Official character profiles and original works take precedence. Source links are visible on each comparison so readers can inspect the context. A correction should identify the page, character, claim and a source that supports the proposed change.
Images and spoilers
Portraits identify characters and do not imply that every illustration depicts the precise moment or transformation being discussed. Lists that disclose later story developments carry a spoiler notice.
