I don't even know what to say...... Leo's attack is called lightning plasma isn't it, how is plasma going to even so much as scratch Q? One is stuck on land while the other can even travel through time and space.
@TheRedRose: Honestly i don't know how q might attack leo but i know Leo's attack are as effective against Q as a fly is to an elephant. What do you think Leo Needs to do to be able to do to one who commands time, space, matter, and energy? I would like to hear your opinion as well...
@sceonn: Blitz him, he may be capable of doing all that but does he have the reaction and speed to keep up with a FTL opponent? Leo's Lighting Plasma was stated to be instant by one of Hades Specters. Even in the Lost Canvas. When Leo Regulus used it Tenma only saw a flash of light and didn't know what the hell was going on.
Whatever Leo might attack with it is noneffective. Time, space, matter, and energy is basically existence itself. As for reaction speed i think you need a bit more info the the Qs because otherwise you wouldn't have said that.
@TheRedRose: Reaction speed aside, the Q continuum is a community of essentially all powerful beings, nigh omnipotent some might say. You need feats? How about him snapping his fingers and sending himself and the cadet in question, 10 years into the past? Or perhaps Q, again snapping his fingers, and sending the Enterprise 7000 lightyears out of the way in a matter of seconds (s2,e16 :Q Who?). I'd say those are fairly substantial feats, wouldn't you? Who needs lightning fast reaction times when you have control of matter, energy and time in general?
Quote from the video Djsnuva posted, "You're not afraid of a little space-time continuum meddling are you cadet?" (8:08) I'm sure someone who can throw punches really fast is going to be super effective against someone who can change the course of time. Good call.
