Obsidian has a cunning mind adept at forming the most brilliant battlefield strategies. For the longest of time, he stayed in the shadows carefully formulating the countermeasures that would enable the Autobots to wrest control of Cybertron away from Shockwave and Megatron. After Unicron's attack in the year 2005, Obsidian led the Autobot forces who expelled the remaining Decepticons from the planet. Since becoming a more public figure, he has led many successful campaigns against Decepticon incursions of Cybertron and has been decorated with the highest military honors.

While Obsidian's best-known weapon is his mind, he is also well trained in many forms of combat. He is a student of not just the history of the Cybertronian wars, but those of Earth and Nebulos as well. He even recently took a modified P-38 Lightening Earth plane as his alternate mode. He is an expert in low altitude aerial combat, and is capable of shelling the battlefields below with machine gun fire and ground penetrating missiles while also engaging enemy flyers in tremendous dogfights. In robot mode, Obsidian is skilled at Kratomechafora which allows a combatant to use an opponent's own physical strength against himself.
