Cool-headed and taciturn, he always maintains a stoic demeanor. He often points out when his sworn brother, SparkBeat, acts recklessly or loses his focus. Despite his cold exterior, he is actually incredibly devoted to his brother. He exhibits overprotective and jealous tendencies. His inner feelings differ from his outward appearance. ex) ...SparkBeat, picking a fight again? (I'm telling you, I get worried when you keep doing that!!!)

He tends to act as he pleases, ignoring the rules. Highly aggressive, he will jump into a fight regardless of his physical condition if challenged. He prefers direct confrontation. If it's a fair fight, he will readily accept defeat even if he loses. Conversely, he loathes it when a third party interferes to change the tide of battle; even if he wins as a result, he refuses to accept the outcome. His older brother, FlashVector, does not hesitate to use underhanded tactics to secretly help him win, which causes SparkBeat—who values honor above all—to harbor great dissatisfaction toward his brother's actions.
