Powers

 * Superhuman Strength: Kilowog has very impressive strength due to his size and musculature, though he's not as powerful compared to some other races that are virtually invulnerable to anything, such as Kryptonians or Green/White Martians as well as individuals such as Hulk and Doomsday.
 * Superhuman Stamina: Kilowog is surprisingly agile despite his size.
 * Invulnerability: Kilowog is surprisingly durable, even without his Green Lantern ring.

Abilities

 * Indomitable Will: Kilowog was chosen as a Green Lantern because of having an "Indominatable Will". When commanding a Power Ring, Kilowog is superemely powerful, coupled together with his own natural strength and stamina, which increases his power when wielding his ring, which is why he is the chosen Green Lantern trainer. His Power Ring of Will enables Kilowog to create a Green Aura that surrounds his body and transforms his clothing into Green Lantern attire. It also enables Kilowog to create any construct that he can imagine, fly and enter hyperspace and also create almost impenatrable force fields.
