This is mech series created by the same people who made FLCL, so by now, you already know that it's pretty much awesome. It stars a young meek boy named Simon and his brother from another mother named Kamina that's looked as one of the most epic guys in the series (But Simon does gain his level of awesomeness as the series goes on) and also the fanservice girl, Yoko. Simon is the pilot of the mech Lagann and uses it to combine with other mechs and fight many enemies in the series.
