Anime Ash's Squirtle stomps, but otherwise, Charmander.
All I know I that characters like Imperialdramon Dragon Mode are WAY faster then the entirety of the Narutoverse. So, unless we find out Imperialdramon is FTL, nobody in Narutoverse is lightspeed. And Imperialdramon does have truw feats, i.e. flying across continents in mere seconds, while although not lightspeed, is helluva lot faster than Narutoverse.
