Falco Lombardi all the way. He takes the role of "That cool dude who goes away, then shows up last-second to save your ass" several times, including in the SSE. Not to mention his amazing advanced tactics!
-Enemy approaching you? Short-hop lasers!
-Just started a match? Chaingrab them to 50%, then spike them off the ledge!
-Want to get back of stage? Drop down, jump, falco phantasm back on, and if you time it right, you can lead right into an up-tilt!
-Want to approach? Short-hop Dair, short-hop double lasers, DLX, short-hop insta-phantasm, the list is endless!
He is just so diverse in so many ways... better than that spamming, stupidly-high priority meta-nuisance...
