My favorite blue Aura wielding Pokemon will be joining the cast of Smash Bros. once again. Yes, Lucario has been confirmed for Super Smash Bros. Wii U/3DS. We also know from Sakurai’s post that the influence of his Aura has been increased. For those who aren't aware, when Lucario becomes more damaged he becomes more powerful.
Sakuari also mentions that Lucario only appeared in Super Smash Bros. Brawl due to the staff’s extreme effort in increasing the game's roster count. As of right now we have no screenshots on his final smash, leaving it up in the air if it will stay the same or will be related to his mega evolution.
