Yes you can. In Melee:
1. Go to 1p Mode
2. Press Regular Match.
3. Press Adventure Mode.
4. Set the difficulty level to 'NORMAL' and choose any character you want. Make sure you have 5 lives.
5. Go through Adventure Mode without using any continues. You must get to the Bowser stage in 18mins or less.
It's a little simpler in Brawl. All you have to do is unlock Bowser, then get a smash ball. Bowser's final smash is Giga Bowser.
There are two ways to face him:
1. Event 51, although both Mewtwo and Ganondorf will aid him. Good luck.
2. In adventure mode, use medium level and don't lose a life or use a continue. After you beat regular Bowser in the end, Giga Bowser will appear afterwards. Lose all your lives here, you won't get a second chance and you'll have to start all over again. If you manage to succeed, you'll earn his trophy in to your collection.
Smash a Final Smash Ball Bowser.
There is a glitch, however, that allows you to play as Giga Bowser until you are KO'd. Play on a level with materialising ground (such as Bridge of Eldin). Get a Final Smash Ball as Bowser, then wait until the ground is reappearing. Jump in, then press B. You should, if you did it right, be Giga Bowser on top of the bridge, and you will be until you are KO'd.
This glitch also works with Jigglypuff, and a variation works with Kirby and some other characters.
You can fight giga bowser but not play him.
with a hack.
No, Wario isn't in Melee.
NO HAXXORZ REQUIRED XP. You can play as regular Bowser who, after getting a smash ball, can transform into Giga Bowser for a time.
You have to be Bowser and get the Smash ball. It's Bowser's final smash.
... He is already unlocked when you start the game... unless you mean Giga Bowser. Giga bowser is only playable as a final smash for Bowser.
Yes but temporarily by obtaining the smash ball as Bowser then pressing the special attack button (B for example).
Sorry, but Giga Bowser is an NPC (Non Playable Character). He can only be played as through Action Replay or in SSBB
yes,you can play giga bowser in melee with a action replay
You can play giga bowser in the debug menu.
Use the "play as Giga Bowser" code.
The only way to play as Giga Bowser is to use Bowser's final smash in Super Smash Bros Brawl.
if you do a glitch or mod then yes but no
It's not possible to do so at all. The only way to play as Giga Bowser is by using an Action Replay.
you can play as giga bowser with the action replay and yes 2 people can playat the same time
