Onomatopoeia always wields two semiautomatic handguns, a sniper rifle, and a hunting knife. As Baphomet, he has shown that this is not necessary to him, but rather a personal choice.

It is unclear whether his mimicry is exact or not, that is, whether for example he simply repeats the word "blam," or actually makes the noise of a gun being fired. When in costume, Onomatopoeia speaks entirely in onomatopoeias, imitating sounds around him. He is possibly superhumanly durable, given his ability to withstand unusually high levels of damage with little apparent effect, however this is unconfirmed. It is unknown whether Onomatopoeia has any superhuman powers or abilities. He is very intelligent, and a skilled manipulator and liar. He is a weapons expert and gifted marksman. Onomatopoeia is an extremely skilled hand-to-hand combatant and athlete. He is later imprisoned in Robin's dungeon. Onomatopoeia appears once again, this time facing off against the Teen Titans. Batman turns in time to see Onomatopoeia slitting Silver's throat. Onomatopoeia finally reveals his true identity by imitating the noise Batman makes when putting his utility belt on the table. Eventually, Batman brings him to the Batcave and identifies himself as Bruce Wayne, introducing Onomatopoeia to Silver St Cloud. He eventually unveils what he claims to be his past and his secret identity. At one point, he fills in for Batman, fighting alongside Tim Drake, who is impressed by him.
