There are many people who like that kind of people. A prime example is Cody and Sierra from Total Drama: World tour. He wants one but then when he gets one he hates it. Also sorry for getting slightly off topic.
If Kellam gets top four they won't give him a legendary weapon. They'll give him a legendary skill call chance miss. Where he has a set chance of a move missing him due to nobody notice him.
I forgot about Athos. He would be a nice unit to have in game. The only problem is that Athos would have his legendary weapon so I doubt he'll make it to top four maybe a later release characters.
