Both star platinum the world and emperor, since they’re both good in damage, emperor the most because he does a crap ton of damage plus he’s ranged so he can basically rekt every stand ingame

emperor: bullets are slow, so it's painful for long range. other than that its ok

star platinum: the world: the ts counter is powerful, so thats pretty gud

kars: combo master

spin: i've used the F move on it before and it brought a kars down to red hp, so it's good

hierophant green: most powerful, better than pot platinum. JUST BECAUSE NO ONE CAN DEFLECT THE EMERALD SPLASH
