Fat Princess is a very close range melee focused character with few ranged moves; her exceptionally strong non-combo attacks build AP very rapidly.
+ Mash (Ballerina Spin Slam) This move is arguably the most useful move fatty boom boom has. This creates a whirlwind the on both sides as well as above and below to some extent ending with a butt slam sending enemies flying away from you; this can be used in junction with other movies such as + + + Mash to generate a very large amount of AP in a few blows; this movie however locks you in place and is punishable.
Level 1 Super can be hit confirmed by the following moves:
Ironically Fat Princess is all about air control, despite her large size. All of her best moves are the ones that she can execute from the air and she has plenty of attacks which provide lots of stun, enabling her to drop down from the skies and lay down some amazing combos. The best method of controlling the air and keeping pests out is her air , a fast acting swipe with her cupcake scepter which sends enemies plummeting down and leaves them stunned for a short amount of time. While playing as FP, you should be focused on catching opponents off guard and laying awesome AP burst combos on them, then CAKE, PLEASE!.
While in the air, morbidly obese Princess Peach has plenty of ways to stun enemies on the ground then come down and deal ridiculous amounts of damage. Her air is the most dangerous of her aerial arsenal, sending one of her loyal soldiers at her enemies at an angle with absolutely no risk to FP herself. This soldier, on contact with an enemy, will stagger them and allow FP to follow up with one of her many very strong combos or even a level 1 super. Additionally, she has other airborne attacks such as her air and which will accomplish the same task as her soldier but at more of a risk to herself.
The super you will be using most as FP is her Level 1 cake rush. As mentioned before, her attacks provide an amazing amount of stun, allowing her to hitconfirm almost all of her moves straight into her level 1. While her level 2 chicken can potentially provide 4+ kills, it's unreliable and incredibly inefficient on larger stages because of it's slow movement and telegraphed attacks. Fatty P's level 3 is a spectacular fireworks display, summoning hoards of her wizards, soldiers and explosives experts to come and dominate the field but it's entirely useless. The swordsmen don't kill enemies but simply stun them and the fireballs as well as the bombs can be easily dodged. Do not use it for anything but humiliating your enemies.
Jabba the Hutt's hard-counter is other aerial characters such as Jak. It's important to try and keep them pinned to the ground, otherwise FP will never get a single hit in. Her is useful for knocking these airborne characters away from you, allowing you to focus on other enemies.
