Bleach IX: This isn't even my final thread!

[The Troubadour]

the thunderbolt [...] ha[s] to be [one of the] lamest power[s] to get.

Not necessarily. From what we can see, she can throw around a powerful ranged attack (possibly at a lower "mana" cost than an equivalent Kido would have) willy-nilly and also move around at a speed that lets her dodge Kenpachi's attacks. It's a very simple power, true, but it seems to be quite effective as well.

But I agree that, so far, The Power seems to be quite limited: all it does, apparently, is increase Meninas' strength (unless it somehow boosts all of her physical - or possibly physical AND spiritual - abilities, in which case it's actually quite strong, even if also very direct).
