Alright that's cool. I still haven't specified whether or not Lily is actually in the mech, because having her inside it puts her in actual danger, as opposed to it being a remote control thing because that'd just be boring.

Why not do both? Have her inside battle armor mech suit, jump down from a building and introduce as she presses buttons on a remote in her suit's arm... That way she's not in any actual danger, it's not boring and she can safely control it via remote with little to no interference and with little worry of it getting hijacked.
