I have a top 3.
Number 3: Samaus
Samus is a decent fighter that can take a lot of damage before being knocked out.
Also her missles are great against MetaKinght spammers. Also a well placed chargeshot can ruin someones day

Also ZS Samus is inceredibly strong! I thought she was gonna be weak but no! Her side-b has a nice kick if it connects.
Number 2: Ganondorf
Once again hes a CF clone but meh. I love Ganondorf, he exudes power. He sweats evil and if you cross his path he will grab you by the face! I dont really like
his falcon punch thingy cause its really slow, but if timed its pretty close to an auto ko.
Number 3: Toon Link
When I first turned Brawl on I found myself highlydisapointed with Link, he just didnt feel right for some reason, he just felt sluggish. But upon unlocking Toon Link I was friggen happy! Toon Link is super fast and super useful. In melee I use to never use the boomerang but now I use it all the time, its great for stringing together combos. Also his down arial attack is always fun. I always use it to pogo on peoples heads.
Here is one of my favorite strategies with Toon Link. I get high above the enemy and pull out a bomb, I drop the bomb on the guys head and at the exact instand the bomb blows up I down A on him to pogo him to hell.
