I like your choices, except for Regent. Regent would probably take a humanoid form, with a crown. After all, it controls the human nervous system. The crown is because of how arrogant his Father is, and therefore his shard as a bud is. "Worship Me" is a powerful ability, after all.
Miniature Vampire? Lamia? Mind Flayer?
All I know, is that Lung's shard would be a Tarrasque.
Yeah. Nothing says run away like a Tarrasque.
There is a power worthy of the Dragon. "Three times a day, if Lung would fail at an action, he can choose to succeed instead". Honestly, though I have never played Pathfinder, the description perfectly fits Kenta.
Mind Flayer would work, as would Vampire. Lamia I don't think would be as good.
Lamia's have this whole slowly enthralling people thing though. I do see how it wouldn't work though.....
Most likely. It was explicitly stated that the GRID could pass both Power and Information, and [Queenie] has potentially infinite power.
