I would think they would be moves the Pokemon can learn some way without hacking the game. Mega Forms aren't allowed for Charizard due to his final smash being a Mega Form. This is not a thread to nag Project M to add in a Smash, just speculation is all.
Charizard Blast Burn: Charizard's body becomes engulfed in flames. It then punches the ground, sending a wave of energy into the earth which then moves underneath the opponent. The energy then bursts upwards in a giant explosion of red-orange flames.(Basically Great Aether I would think with just the slamming effect with multiplied power and a Stamina Drain that can only be achieved through this Smash)
Squirtle Hydropump: I would imagine it would be a clone of Samus' Final Smash, just with different sound and effects.
Ivysaur Sunny Day: Unlimited Solar Beams for a short time.
Just my speculation/suggestionsSeriously though the Ivysaur one should happen xD
