Who's the most underrated MLP character?

[Tao 7,329]

Big Mac,   one of the few stallions we see a LOT and used just a place holder most of times sadly.  I mean who runs the farm while AJ is away on magic stuff and helping to raise his little sister and help his granny?   Big Mac is the pony's name.  I think he needs some good or a few eps or parts to show all he does and stuff for his family and farm.
