It's weird cause the only person we know to have 1 devil fruits is Blackbeard (possibly imu too but we don't know) I find it really really suspicious we've only seen 1 person have 2 devil fruits but we've heard that "oh it's dangerous to eat 2 devil fruits" yeah, I'm calling bullshit. Thats a made up lie by the government, or it is true but you can't have 2 of the same types of devil fruits, it just wasn't specified
