Axel Gear is a ruthless figure with nothing else in mind but his own selfish goals, showing no regrets in kidnapping one of the princesses to blackmail their respective fathers for his own purposes, or killing Mifune Sanjulo to get his hands on the Secret Book of Rocket Knights. He is a traitorous being, not only betraying the Kingdom of Zephyrus but also planning a rebellion to overthrow the late ruler of Devotindos Empire--Emperor Devligus Devotindos. His lack of loyalty towards everyone makes him untrustworthy in all regards as he clearly only cares about himself and all the ways he could achieve his goals, even if it means to harm innocent people or teaming up with other kingdoms that want to conquer the Kingdom of Zephyrus or Eginasem. Despite his disloyal trait, he is very competent in what he is doing which is the main reason why he gets hired. His rivalry with Sparkster is not to be taken lightly. While the Black Knight was beaten several times it only fueled his desire to grow stronger and finding more and more ways to overthrow the Rocket Knight--Even if it means to use a big variety of gadgets just to have a greater advantage. But as much as he seems to despise Sparkster he also has no shame in provoking, taunting, and stealing the spotlight from him whenever he is able of doing so. In this game, he's one of the generals of The Agents of Darkness, and will occasionally interrupt our hero's progress! But knowing his dishonest nature, he's most likely showing his loyalty to his "allies" just to backstab them in the last minute. But however, doing so will most likely be his demise...

He sounds cunning yet cocky, not afraid to get his hands dirty and likes to taunt his foes... a lot...
