First of all, don‘t mind my bad grammar as I wrote this suggestion years before. Wanna get this suggestion implemented nonetheless as I think it‘s still very easy to implement. It‘s basically a better version of Kilo Kilo no Mi being more diverse and dealing more damage, however taking longer cooldowns and slower charge up time. Long story short, this is how it goes:
Heavy Push: Basically a horizontal push technique. First you aim at an enemy (max range 15 blocks or sth) after activating the ability you thrust yourself at the enemy pushing them back and because of the massive weight ongoing, the enemy gets damaged and flies away, creating a crater on impact where he crashes in. so simple yet interesting.
Featherly Jump: this ability causes the user jumping and floating in the air he acts like a feather. This ability is a build up for following attacks…
Ton Ton 10 Vise: by activating that you fall with a weight of 10 tons. When hitting the ground, it demolished the affected area instantly and creates a crater which get bigger in stepps (like fujitoras jigoku tabi) there are several hitboxed based on how near the subject is to u attack.
1000 Ton Vise of Destruction: enemy even gets higher amount of damage, and large cooldown gomes after that leaving a big crater that shows your terrible weight. Besides the destruction, Blocks will get blown through the air like it used to happen in good animation or with fujitora‘s meteorite ability.
10k ton vise of hell: This ability elevates the fruit to iron box tier. It‘s just like the 2 before but deals way more damage and it doesn‘t spares any subject nor object in the aoe. Creates a really massive crater which is obviously supposed to occur when 10 grands of tons hit the fucking ground.
This fruit is very underrated as gotten used by a goofass character, but who cares, if the fruit itself is gasss. It‘s certain that in the hands of the right one, this fruit is a solid choice for grounded pvp and griefing.
