White hero, sidekick of color: why Marvel needs to break the cycle

A roughly 100 year old-plus White Savior trope in Western adventure/superhero stories, designed to cast the hero as a friend to all peoples, and the (white) reader/viewer to feel similarly to the hero without actually fully developing the sidekick beyond being a tool that imparts information to the hero and further defining the White Savior’s mission and even domestic/romantic life elsewhere in the series.
