Third Doctor

A swashbuckling action hero who was not afraid to beat up his enemies with Venusian Aikido, conform to traditionalist values of respecting authority, and drink alcohol on prime time children's television, the Third Doctor's character was heavily influenced by his actor Jon Pertwee as well as the unique format of much of his early era which grounded the Doctor on Earth and paired him up with UNIT to fight alien threats on Earth.

The fact that this Doctor couldn't get his TARDIS to fly for much of his early tenure made him rather grumpy, but like his first incarnation the grumpy persona was merely a veil hiding a gentle and reserved man beneath. This Doctor was probably the most human Doctor yet, and some of his actions seem questionable compared to later incarnations. Nonetheless, he remains one of the most unique versions of the Doctor ever put to screen.
