Giga Bowser

''For the trophy, see Giga Bowser (trophy). For Bowser's Final Smash, see Giga Bowser Transformation.''

Giga Bowser (ギガクッパ, Giga Kuppa, Giga Koopa in the Japanese version) is a gargantuan version of Bowser. To fight him, you must clear Adventure Mode on Normal or higher in 18 minutes or less. Then he'll appear after you defeat Bowser. Defeat him without using a continue and you get the Giga Bowser trophy. He also appears in Event 51: The Showdown. Some things that separate Giga Bowser from Bowser are:
 * Approximately 1.7 times larger
 * Infinite flame breath
 * More height gained from Fortress
 * Fortress grants 26 Invincibility Frames, and pseudo Invincibility Frames after the 26, due to the enormous hitbox.
 * Cannot be grabbed
 * Forward tilt sets opponent on fire
 * Down smash freezes opponent
 * Forward smash creates a large explosion
 * Neutral aerial electrocutes opponent

Giga Bowser is also slated to return in SSBB as Bowser's Final Smash. (See Giga Bowser Transformation)

Falco
Giga Bowser is a pushover when playing as Falco. simply roll to the side and get that blaster to work. It won't slow his advance much but the damage will rack up. When he's getting near you, double jump above his head and use your Fire Bird (B+up) but remember to aim downwards at him. After hitting him roll away quickly to the other side and repeat this process until you win.

Jigglypuff
Just float around a lot, then use the Rest move whenever you get close enough.

Yoshi
Just use the Jump then use the Yoshi Bomb just make sure he dosen't use his because that will be bad.
