Storm. Black Lightning. Static. A lot of black superheroes have electricity related superpowers. Charles Pulliam-Moore looked into the reasons:

• Black characters are often written to be closer to nature – an unfortunate trace of when they were depicted as savages.
• The tamable nature of lightning might also be an unconscious expression of bias.
• Lightning is powerful enough to make yourself known in a fight. But when you’re teamed up with, say, Superman, it’s not enough to win the battle. Since black characters are often side characters this suits writers well.
• There’s probably an element of competition. DC has Green Arrow. Marvel has Hawkeye. There’s also Deadpool and Deathstroke, and Darkseid and Thanos. When one company released a black lightning character the other eventually followed.
• Nonetheless heroes like Storm have grown to become strong characters who are more than just their electric powers.
