Paramecia: Gas Gas no Mi - Able to produce an unlimited amount of various gases from your body. Use: Sleep gas, instantly puts everyone into a deep sleep if inhaled. Doesn't work on high level haki users (imagine you use it on a whole marine fleet - but unable to affect an Admiral). Another gas would be laugh-gas, when inhaled your opponents turn crazy and absent minded. Doesn't work on already "crazy" people, like Luffy and Kizaru. The third idea for this fruit would be ignitable gas - you shoot a current of gas at your opponent and set it on fire. For the fun factor you could add fart-like gases. The major weakness of this fruit is that it doesn't make you immune to fire - means if you don't watch out you can easily ignite yourself.

Logia: Crystal Crystal no Mi - Able to become and produce unlimited amounts of a crystal like matter. The main use for that fruit is to build sharp and spiky crystals all over your body (like a hedgehog)and to shoot crystal bullets at your enemy. The crystals are not as hard as steal, but able to withstand a good beating. Also, since crystals can't rot, the user can create and form his own island or buildings based on the crystals he creates. Weakness: No standard weakness except water (the user), but the pika pika no Mi (Kizaru) is it's natural enemy, since the lightbeams can't pass through the crystal. The light would simply reflect itself inside the crystal and cause excessive damage.

Mythical Zoan: Hebi Hebi (snake snake) no Mi, Model: Basilisk The fruit can turn you into a basilisk, a huge snakelike being with wings, sharp claws and a beak similar to a falcon. It generally enhances your melee combat powers and allows flying (for short distances). The users blood also turns poisonous. Making direct contact with it will paralyze you in seconds (for about one week). This is the main strength of the fruit - but also its greatest weakness. The blood of the basilisk vapors only a few seconds after leaving the users body - so in order to use the blood as a weapon, the person needs to constantly cut himself.
