Muscle-Muscle Fruit (Need Re-Approval!)

Name: Muscle Muscle Fruit ( kin' niku No Mi?)

Description:

Here's how it works. You can change your muscle structure in order to increase your strength/speed by 100% but there's a trick. The increase of speed and power together must not be more than 100%. There has to be a balance between strength and speed meaning you can have your strength increased by let's say 20% and then your speed can be increased by up to 80%. And so on. You get the point. Either your speed is increased by a certain amount (from your original speed limit) or your strength is increased or both. The increase/decrease in speed/power takes 1 post.

By increasing your speed you can move faster (throwing faster punches, kicks, more likely to avoid stuff, run really fast) but your attacks are in turn less powerful/damaging.

By increasing your power you can attack with a more deadly force (more strength) but become slower and less agile but are also able to
withstand a bit more damage yourself. (your muscles being hard and all)

It can also activate a special mode called 200% mode (Hyper mode) that can increase your power and speed both by 100% or either strength or speed by 200% but can only be used for a very limited time plus your body is a wreck afterwards. A bit like the reject dial or what was it that really has a heavy burden on the body.

Type: Dunno

For starters, it's definitely not a logia. It would be a paramecia.

Secondly, this seems to have no coherent theme, it's just more a collection of powerups with no unifying concept. More reminiscent of a random superpower than a devil fruit.

Thirdly, linear scales rarely work very well with "strength" and "speed" here.

Fourthly, why? You could create a similar effect with life return by altering your body. Speed fruits haven't been allowed before, simply because there's no point due to the ease of which it can be obtained otherwise.
