Well, i've got another idea to Crusade, Sunflower, from PvZ series. She would use a sun-based system, every time you press B, she will produce sun to use her moves. Here's her moveset.
Normal Combo: Slams her head at the enemy 2 times then shoots a small sun beam at the enemy.
Forward tilt: Shoots two sun beams at the enemy.
Up tilt: Headbutts the enemy.
Down tilt: Puff-Shroom: Summons a Puff-Shroom that shoots at a small range.
Forward Smash: Bonk-Choy (75 sun): Summons a Bonk-Choy that punches the enemy three times.
Up Smash: Cactus (75 sun): Summons a Cactus that grows up and hits enemies above.
Down Smash: Spikeweed (100 sun): Summons one Spikeweed in each sides of Sunflower.
Neutral B: Make Sun: Gives you 75 sun each time you press B.
Forward B: Fume-Shroom (125 sun): Summons a Fume-Shroom that throws toxic gas at a long range.
Up B: Umbrella Leaf (50 sun): Summons an Umbrella Leaf under Sunflower that boosts she up in the aky
Down B: Cherry Bomb (150 sun): Summons a Cherry Bomb that explodes, damaging the enemies and Sunflower.
