Claude Speed from GTA III and Leo Kasper from Manhunt2
I played both games recently, which are both in the same universe as Rockstar eplied. I've noticed something interesting, that Claude and Leo Kasper are actually looking like the same person, not just visibly, but even in personality. Both are cold-blooded killer, both suffer somekind of trauma, and both chose the way of crime.
Further more, both were born around 1972. And think about it, Leo is a goverment agent that underwent extensive training in areas such as close-quarters combat, evasion techniques, and covert operations, that may explain why Claude is an expert at bank heists and dealing with all types of weapons
I feel like somehow, the Project in Manhunt2 had succeeded to make a the weapon they wanted to, by using Leo's personality, and maybe that successful copy was Claude, that may explain his silence, that could be a side effect of the transport of Leo's personality to his body.
Or, based on the community, Leo Kasper died of unknown causes and had his personality sampled by The Project for future use. But, maybe he survived and escaped, just like Claude did when Catalina turned on him. As for his silence, maybe it's because of The Project attempt to sample his personality, and that experiment left him like that.
This is just a personal theory appeared inside my head when I was playing Manhunt and it seems pretty convincing to me. What do you think, guys?
