First of all let me just say that Michael Gruber is the most impressionable Munkustrap I know.

I believe that Munkustrap is Grizabella's son, Old D.'s Grandson
(being he is the oldest member of the tribe!), and Tugger and 
Macavity's brother. I think that Munku is the runt, Tugger is the 
oldest and Macavity is second eldest. Munku is definitley the one who 
gets along with Grizabella and Old D. the best.

Munkustrap supposedly has a relationship with Demeter, and I think 
it's true, but he never proves it! Still, I think she is the 
best ,ate for him because the other girls are too groupy, young, 
hyper, quiet, clingy,flirtacious or arrogant(no offense to 
bombalurina because she is my second favorite girl but she is 
arrogant).

Munkustrap is the strongest (not phsically) male character. He 
protects the others and he knows where he stands. If I were to 
describe him in five words, I would say : protective, brave, serious, 
respectful, and handsome.
