You must be thinking of an old version, in which the secret character was the Invoker. He wasn't particularly good at the time, just interesting due to the nature of his spells and the use of the ball combos for different spells. He is now a normal character though. In 6.59D you can unlock the Tauren Chieftan. He is rumored to be the new hero for 6.60. The unlock process is pretty complicated. I woul d suggest you you tube it, there are videos explaining how to unlock him.

Limit Break levels 2 and 3 are unlocked by having that character kill a certain number of enemies - the amount is different for each character. The second Limit Break of each level is unlocked by having the character use the first limit break of that level multiple times, again, it is different for each character. Once unlocked, the character has to have their limit break level manually set on their status screen. Note that level 4 can only be unlocked using an item, and that Cait Sith only has 2 levels in total.
No. Tabuu is only a boss in the game and cannot be unlocked for gameplay.
