GOD
Fox/Falco/Wolf - Landmaster: Ok
Sonic - Super Sonic: Ok
TOP
Captain Olimar - End of Day: You can avoid the final hit without too much difficulty depending on character and stage.
Mr. Game & Watch - Octopus: Ok
Wario - Warioman: Ok
Snake - Grenade Launcher: Ok
Captain Falcon - Blue Falcon: A bit hard to hit... can you combo into this?
Luigi - Negative Zone: Ok.
Ness/Lucas - PK Starstorm: Easy to avoid in a one on one.
Marth - Critical Hit: Ok
Ganondorf - Beast Ganon: Ok
Ike - Great Aether: Ok
Meta Knight - Galaxia Darkness: The range is mediocre and it doesn't KO until somewhat high percentages. Can you combo into it?
High
Yoshi - Super Dragon: Ok
Ice Climbers - Iceberg: Doesn't really seem to do that much besides a bit of damage. By the time you get to the enemy its half over and they can still fight back reasonably well. If you don't have Nana its very hard to hit them at all.
Link/Toon Link - Triforce Slash: Better than some of them in the tier above.
Samus - Zero Beam: Ditto.
Bowser - GigaBowser
Lucario - Aura Storm: Can easily be avoided by a decent player.
Zelda/Sheik - Light Arrow: Ok
Pikachu - Volt Tackle: Ok
Pokemon Trainer - Triple Finish: Sadly no Long start up and unless you hit with the middle of the attack they'll often bounce off of it. Mid tier at best.
MEDIUM
Diddy Kong - Rocket Barrel Barrage
Mario - Mario Finale: Can be hard to KO with and does like 20 damage or so if it doesn't hit them off the stage. A tier lower.
King Dedede - Waddle Dee Army: Reasonably easy to dodge. Maybe a tier lower.
Pit - Paletuna's Army: Ok
Jigglypuff - Puff Up: Can be either useless or incredible depending on the stage and character. I guess its ok here.
R.O.B - Diffusion Beam: Rob isn't the fastest character so this can be easily avoided. Down a tier.
LOW
Zero Suit Samus - Power Suit Samus: Yup. Easily avoidable/DIable and transforms into a worse character.
Kirby - Cook Kirby: This one is right. Stupid avoidable cook.
Peach - Peach Blossom
DK - Konga Beat: No. Pressing A makes the attack much larger and more damaging. Used at the right time this can be pretty devastating.
Fox/Falco/Wolf - Landmaster: Ok
Sonic - Super Sonic: Ok
