Ron Swanson - SLI
Tom Haverford - EIE
Leslie Knope - Alpha Extrovert
Ann Perkins - not sure, she's one of the 'normal' people foils on the show. INFx, maybe?
April Ludgate - ILI
Andy Dwyer - SEE
Jerry Gergich - Not very well developed character that gets shat on by everyone else in the office.
Donna - Also not very well developed. Jean Ralphio reminds me of Gilly!
Mark Brendanowicz and Dave (Louis C.K.) - Idk, not too sure. Louis C.K.
Some kind of Si-egos? I'd guess SEI (or EII?) and maybe LSE (though that's more Louis C.K. and less the toned down character he plays on the show).
