What about the fan favorite Ike Climbers?
But jokes aside, I'd have to say Roy considering his slightly charged forward smash can kill at 45-60 on a lot of characters. His Neutral B also has surprisingly low lag, and if the enemy's shield is broken then Tier 8 Eruption has nothing on not-even-fully-charged Flare Blade. Although I have to say that Ike's recent buffs has really improved his overall gameplay, even if he still isn't in peak form.
Roy Pros: Agile, powerful, not too much lag, can combo out of grab easily, is our boy.
Cons: Recovery doesn't have great vertical distance, have to practically be touching to hit sweet spots, gives sympathy
