Lightning is the requisite speeding superhuman on every team everywhere in the comic cosmos. His plight of aging inexorably with his speed was a curse as much as a blessing. The suit he wore, keyed into his specific physique, was the means to accomplish daring deeds of do-gooding. And just when he was ready to retire, another emergency required he resume his role-player role.
And now, we meet a new Lightning for a new era. This may sound a bit obvious, but it must be said that he reminds one of Marvel's Blur... which is not a bad thing by any means. In the homogenized early 1960's, heroes of color were taboo until a slew of "Black" dudes appeared on the scene (i.e. Panther, Goliath, etc).
Here is hoping that is characterization is spot on and not stereotypical, which there is a good chance of given the creative forces on this project.
