Being honest, I have to say that I won't rely on lolis to command and pilot a mecha army; there are a lot of reasons to it, (including the classical Rule of Thumb among movie makers: 'Never work with kids and animals') but the biggest deal about it is that mecha pilots (even Super Robot pilots) are susceptible to great amounts of angst and stress. Ergo, you have to be a bastard to actually rely on such fragile kind of individuals for that kind of task.

And I'm looking at you, Gendo Ikari! >:(
