SSB4 with characters: [u'Bayonetta', u'Samus']
To be honest, there is an edge to Samus in this matchup. Samus can punish every single one of Bayonetta's slide moves with a charged B and yes, that is very easy to do since Bayonetta relies on her slides to start combo's. BUT Bayo has an edge in air. Because, no one has a chance against Bayonetta in air...
