[quote=@Nytem4re] I think a rp based on a show where they somehow have flying ships and mecha, it's not too hard to believe that someone might have a mini reactor implanted in them (Gren could literally just say he has an artificial limb and I doubt the people checking, if at all, at a metal detector, would try say nope you can't go in.) And here's the thing, RWBY doesn't follow rl logic strictly. I mean flying military ships, semblances? Mecha? keyword is "None of the ones we created". Pretty sure RWBY doesn't follow the tech tree of reality. They have plenty we don't have. How much energy Gren would need is never really specified anyway so there's that. I doubt he needs the full on power a city might need. Whether the RWBY world is capable of creating a small scale fusion reactor, I will have to admit, is a bit of a stretch. [/quote] Frankly, not following real life logic makes it [i]more[/i] dangerous. Lucius himself said; [quote=@Lucius Cypher] However I also chose a purposely less advance and possibly more volatile alternative of nuclear power instead of an Arc Reactor to give the impression that Gren, compared to someone like Penny, uses older quality stuff. [/quote] Key words are "less advanced" and "possibly more volatile". A fusion reactor in suitably advanced settings could be hand waved as safe due to having certain fictional safety measures, but a less advanced reactor implanted in one's body that may very well not have worked, in a setting that produces most of its technology through Dust, would not have advanced measures like that. At the bare minimum, a self sustaining reactor breach would produce an immense amount of very, very bad radiation. More likely? An explosion that is, at the size it would be to be implanted in one's body, equal to or just under the size of what we inflicted on Hiroshima. As in, enough to level a city. And that's without even touching how the tech would be developed given that almost everything in RWBY runs on Dust.
