I think moonmaker was refering to James. Even I really don't think James is (blank), he's just bizarre. He's had attractions to girls before but nothing in Hoenn.
Guess Hoenn women aren't that special. Shrugs. But that's not the point.
Alter Ego, you're certainly right about that about the Bosses, although should we factor in Giovanni's past into his motivations? Like his mother and the roles and obligations? Don't see any origin stuff for Magma/Aqua, special episodes or not. Although a CD Drama would be funny.
To go one step further about the organizations themselves, as I think, I see them as products of their times and deepen the personal impact/allegory. Team Rocket's theme/connection to money is more of a sign of Japan's economic dominance and becoming one of materialism (almost like America, winks) and the fact with the money with Japan's whaling, obviously feeds into the Rockets' mentality to hurt and exploit animals for profit (this is particularly observant in Pokemon Special).
On that note about the whalism, with the American liberal environmentalism plus Japan's remorse (the series is so littered with environmentistic messages) no doubt fed into Aqua/Magma in that of their playing the environment, making that the priority, although their respective final goal for more land smacks too much of Japan's overcrowding issue really. Although of the two, Magma's plan makes sense, I'm unsure about Aqua's with more water, do they plan to live underwater or evolving everyone into a fish hybrid? The organization should have scientists working on this (Heck, for Magma, they had Butler, a geneticist) or some allusion to.
Given the greed for a better life is more prevalent with most of humanity, I can see the Rockets' popularity (not to mention their diversity) being such a fan favorite for we're a stone's throw away of wearing a black uniform because of the search for money as that can lead to a better life. (Although with Magma/Aqua's fanatism, I suppose it can be timely with the Muslim Jihad/War of Terror we're engaged in but given Japan's blaiseness with that, and the more obvious issues of overcrowding and more fantasy fare, I really rather doubt that, but I did want to leave that out there).
Or course, it doesn't always work as seen with Jessie and James but that makes the human connection that more impactful than seeing a bunch of nameless fanatics kill everyone for the sake of a few's insane ambitions and...a weird detachment with that. Although that could be with the exception of Homura/Isabel, we don't see much of a human face on this.
