In very early comics he used to laugh and have some goofy moments. He used to say more than " . . . " and " . . . I'LL SEE WHAT I CAN DO", also.
I have yet to see any of this, but I hope it's more like the latter comics and Queen Bee, where Golgo is practically a background character compared to the crazy fucking espionage and political thriller shit going with the other players.
