Are there any specific comic book characters known for their signature boxing gloves?

Yes, several characters are associated with boxing gloves. Iron Fist, for example, wears specialized, magically-enhanced gloves that amplify his chi energy. While not always boxing gloves in the traditional sense, characters like Luke Cage often utilize reinforced gloves or gauntlets that provide similar protection and power. Some villains might also use modified boxing gloves with built-in weaponry.
