I imagine you'll get to the more popular ones at some point, but Pumpkin Scissors is a very nice series. It's sort of a mix of elements from Fullmetal Alchemist 2003 (military do-gooders helping and fighting villains wherever they go) and Trigun (gentle protagonist with superhuman abilities and a mysterious past).

You only need one T-Rex to make the point, though.
