Does Lucca's Hypnotize work on everything all the time? I think she would, like I did, completely forget about Hypnotize and go for a slightly...better ability. And it's not that other monsters or kids are in the room w/her, but the fact that she'd have to be worrying about them...I mean, if they're just hiding around, they're gonna die...In fact, w/o Serge, they surely would.
Stated as humans, yes, but they are also the humans that the Entity chose to defend the world and destroy Lavos. Stuff like that doesn't happen to just anybody. Plus, through their experiences, they become more than human. And how is something like Magic overrated? Everything is based on the balance of the four Magical Elements. If anything, Magic is UNDERrated. Not to mention the regular abilities that Crono & Co. demonstrate, like the inner strength/spiritual/ki ability of Crono's tech, Slash. Average humans these kids are not.
If Crono can take a Destruction Rains From the Heavens then, yes, I don't see what the big deal would be in a bullet hitting him. Especially since any guns Porre has probably aren't all that great (seeing how little damage they deal in CC, 20 years AFTERWARDS!!!).
