Ignore the black background, it's made by me. I just posted it somewhere else.

The Cat:

The Cat has four modes.

1: The Cat can capture and move like a Wazir, and move like a Ferz. or they can move and capture like a Dabbaba if there is a enemy piece in it's 2 square radius. If the cat moved diagonally, they can move and capture like a King and the Dabbaba thing is in effect.

2: If The Cat didn't move a turn earlier, The Cat can move and capture like a King, or move and capture like an Alibaba. This is also known as charging. If The Cat moved diagonally two turns before, it can move and capture to anywhere in the two square radius.

3: Fully charged. The Cat can move and capture like a 2-square radius Queen or capture like a 3-square-radius Queen. The diagonal effect is the same as 2.

4: If the cat captures two pieces in a row, it can move and capture like a 4-square radius Amazon. Diagonal effect doesn't exist.

Addiontally, The Cat can jump on a piece (not enemy piece) in his moving radius, and jump on it. The Cat will be able to jump out of the piece to any moving square or capuring square if there is an enemy piece. The Cat can be on top of the piece for 5 turns but it will decrease the charging level by one every 2 turns, and the diagonal effect will be turned off in 3 turns if there's one. The Cat can also move with the piece it is on, and will be able to travel with it.

Happy rider
