Although he appears to be a masculine Orc, he acts very feminine and tends to flirt with any male characters he creates weapons and armor for. He also states that male Golden Saints and Dark Seducers are "dreamy."
He gets very offended when customers visit Cutter, his rival, in Crucible instead of him. If the Hero is male and has Madness weapons or armor, he may say, "You think I'm ugly, don't you? And that SHE is the prettier smith?"
- A script note for Dumag states, "This character was female and now is male, so the editorID and ref name are DumagGrABonk but name is Dumag grO-Bonk (gra/gro)." Later notes in the script refer to him with female pronouns.
- Despite being essential, he still has an epitaph for a tombstone in New Sheoth Graveyard. It reads, "Dumag gro-Bonk, he made killing things fun again."
