A year with so many great characters...
Kat from Gravity Rush. [Holy hell is she adorable. GRAVITY RUSH 2 WHEN?!]
Zero III [fantastic delivery in the English VA sold me completely], Sigma, Phi, Luna and others from VLR
Dunban in Xenoblade (Hey, it only hit NA this year!)
And these are just the games I've played.
But ultimately, I think I need to give it to Handsome Jack.
He was just such an incredibly written, incredibly acted, well rounded villain. One who could be hilarious, well developed, yet was such an evil bastard you absolutely develop the urge and need to deliver retribution to this mask wearing, egotistical, a-hole.
A character you love that you hate, and hate that you love, Handsome Jack is truly a perfect kind of villain. Absolute surprise for me how simply basing the story around being against Jack, Gearbox severely pulled me into the story of Borderlands 2... Which is something I could not say about the first game narrative wise.
