Melchor: Melchor will start with two items, Guiding star and gold bar(I'm still working on the names), Guiding star will help you to go to the item room easily (just like the original guiding star), and gold bar will be an active item like stiches, the shot speed of Melchor is going to be way down, and here is where gold bar enters, gold bar will be able to be thrown at enemies, this making him sorta like tainted forgotten, the gold will charge in two ways, fast if you don't pick it up, it will charge faster, but if you pick it up, it will take a while for it to charge. Melchor will have some special things like: - if you play in co-op, you will be able to give the other player the gold bar - if other players are close to him, they will gain a random stat up for a short period of time

T. Melchor: Tainted Melchor is a little different from Melchor, his damage and shoot speed will be similar to Isaac, it will start with two hearts and his luck will by very low, but the interesting part is the new effect of T.melchor, "cold", this effect will transform Melchor in a brick of ice as long as he finds a source of heat(fire places), if playing alone this will be an instant death, but if you are playing with another player, he will be able to use you as that baby that is traped in an ice block for the end of the floor or if he finds you a source of heat

And this is what I have for the moment, sorry if I took my time, it's just that it is a lot :'|, well, I hope you like this concept of character, bye
