I like Thor, Mr. Peabody, or/and Zeus
But if we're sticking with "T"s then perhaps, Thorton, Theodore (greek - Gift of god), Theo (short for Theodore), Tardis (if you're a Dr. Who fan), Turk, Toddie (like a hot toddie XD), Tony, Thunder, Tobias, Takeshi (japanese - strong), Tadashi (japanese - faithful servant or if you'r a Big hero 6 fan), Takoda (lakota - friend to everyone), Thad (short for Thaddeus, greek for courageous), Thane (english - attendant warrior), Tiger/tyger
