Why did Sephiroth bother summoning Meteor, which takes a couple of weeks to get to and destroy the intended target, when he could’ve just summoned Super Nova like he does as Safer Seph? Super Nova is a comet that pretty much instantaneously travels to the FFVII version of our solar system, blasts through Pluto, past Saturn, cuts through Jupiter, and crashes into the sun. The sun in turn eats Mercury, Venus and then Earth.
