Now you've all got me kicking around my Mad, interdimensionally-infundibulated raccoon Jenna James Kirschbär's backstory.

They're at least second-gen Mad, so I figure it's sort of a family business. So now I'm thinking of them as right at the midpoint between the Murrys from Wrinkle In Time, the Richards from Fantastic Four, and the Gerhardts from Fargo S2.

I think I'm gonna crib admiringly from @Balina's "art of Balinology" for this. Like Balina $LASTNAME, there's a Kirschbär clan in every dimension—except for the ones they've been deliberately rooted out and expelled from.

They usually have their roots in some kind of aristocratic bench-chemist tradition, making the leap to industrialists somewhere along the way. They have a habit of losing their fortunes by backing the wrong side of a revolution or two, usually after some general or chancellor fails to properly appreciate the refinement of their inventions.

JJ theirselves is generally a pure academic and hedonist with no real interest in the power-dealing side of family affairs. They go to school because they're expected to, TF a few friends and enemies because they can, and invariably their attempts to "find themselves" after graduation involve some confrontation with a Big Mystic Other. One after another, they get caught snooping being the curtains and get split into metaphysical fragments for their trouble.

As noted in previous posts here, Kirsch is friendly and helpful on the micro scale and cheerfully amoral on the macro scale. They're not joiners and will only help an organization from the sidelines. They'll work with anybody until they catch them hurting somebody they like, and can go from trusted fixer to crazy-obsessed saboteur with the flip of a switch. Once they decide they don't like you, they're relentless.

They tend to come in designer colors. Red is the default, and a family genetic quirk. They are VERY fussy about not being mistaken red pandas. You can always tell a post-splinter Kirsch and the severity of the split by the palette swaps. If you see them in cyan or mustard, give them a very wide berth. They are not long for this world and will probably take someone with them.
