I'm getting whiplash reading these chapters. I hate this one, probably my least favourite of the series. What the hell is going on?
Goku's sacrifice is in vain.
Cell comes back and kills someone, Freezer style (meaning we've seen it before).
Cell's regeneration is even more over-powered than before. Is this still supposed to be from Piccolo's genes? Bullshit. And where was Cell's core when Goku blew up his whole top half?
Cell is now in perfect form? Why? Because of his strength boost? That doesn't make any sense at all.
Cell has now learned to teleport? He knows other character's techniques because he has their genes, but that only works with stuff they did in the past. We've never seen him learn new stuff from them, and now he's learned what is seemingly one of the most difficult techniques? How?
This arc is Dragon Ball at its most sci-fi, but it all falls flat if the science is inconsistent and doesn't make any sense.
