He will heal and cure your party members. The prices for his service differ from town to town.
Inside the Clone Laboratories you will meet this guy. The fee for cloning one of the party members depends on his / hers level status.
This friendly person will tell you how much experience point each party member need to gain the next level. After this helpful information you can save the progress you made. If you use your Visiphone (get it later in the game) you will contact her use save your game anywhere you like.
She awaits your inside the teleport buildings on Mota. From here you can teleport to any town on Mota you have visited before.
He and all his brothers (they all look the same) are owners of the Motavian Tool shops. Here you find items for healing and transportation like Dimate and Escapipe for example. Sell some stuff not needed anymore in these shops. You only get half the price back, but this is always more as if you simply drop the items.
Here you can buy the armor and other equipment to protect you. Be careful when buying. Not all party members can use the same sort of equipment, and some armor is very expensive.
This lady sells weapons of all kind. She will tell you if the one who will take the weapon can be equipped with it. Trust her, she is always right.
These guys live on Dezo and can be found in the shops on the ice planet. Only the Clone lab clowns seem to have a monopole for their service. They reside in Dezo, too.
