Luka Millfy (Super Sentai: Kaizoku Sentai Gokaiger)

Why He Rocks

 * 1) His catchphrase "Zenryoku Zenkai!!" is awesome as it even makes the viewer watching super hyped up for what's about to happen
 * 2) His powers are also really cool, aside from using the Sentai Gears to gain various powers, he can use a ZenKaiju Gear to become Super Zenkaiser (Based off of Dragon Caesar) and the Zenryoku ZenkaiCannon which can summon various rangers and his own jet

Bad Qualities

 * 1) Is an impulsive and loudmouth idiot with barely any personality other than that.
 * 2) Barely gets any development and while his storyline involves his missing parents, he doesn't get very emotive over it.
 * 3) His suit design is ugly to look at and doesn't even make him look like he's on the same team as his teammates.
