CREATE THE BEST/WORST CHESS PIECES

The 5k runner: Moves 5 spaces horizontally, vertically, or 3 spaces in one direction and 4 spaces in the other.
Like this

A wall, Each opponent has one on the E rank of their side. This piece does nothing to put it simply. It cannot capture nor be captured. Each side may move their wall once a game. you drop the piece wherever you think may benefit you, maybe by creating a smothered checkmate?
One rule: It cannot be moved until side takes 1 piece.

The Roadblock
Randomly moves to any square every move. If the square is occupied, the roadblock removes it from the game, and nobody gets the points. The roadblock cannot be taken or moved. It appears after the first move at a random place.

The Mind Bender
Works similarly to a mind bender in Polytopia, moving one space in any direction. The Mind Bender cannot capture, however, it can turn an enemy piece in moving range into a friendly piece, using a turn in the process.

Pioneer: Has the mixed abilities of both the Pawn and Peasant. It can move to any of the three squares infront of it and can capture on all three. Much like a pawn, it has the ability to promote on the eighth / first rank. They will spawn in place of the queen and king pawns.

mimic is a thing that only a pawn can promote to, it looks like a queen to the other side but for you the mimic has blood on the top. if they capture the mimic it will capture every piece within 1 square of the mimic. the mimic is only added when promoted to. the mimic moves like a queen but cannot capture more than 2 pieces before revealed that it is a mimic

the tower, the tower every 5 moves will capture 1 piece within a radius of 4 squares. the tower replaces the rook, the tower cannot be moved and the opposing king can not enter the area of the tower.

the samurai, the samurai moves 2 squares in every direction but can capture a piece that is 5 squares away, every capture the samurai gets, he goes invisible to the opposing side. only you can see it, he stays invisible for 3 turns. while hes invisible he can move anywhere on the board and could capture any piece beside the king. it will not emideately capture it, when he goes uninvisible the piece is captured and he is shown. if the samurai decides to move to capture another piece while hidden the piece that was gonna get captures gets the samurais curse, this makes them be able to move 8 times then they die.

the mortar, every 5 moves the mortar goes off and fires in a random area on the board, if in a 3 square radius to the blast every piece will be captured, not including the king but it will stun it making the king unable to move for 2 turns, if in check while stunned that is checkmate no matter what.

the little kid, the little kid moves like the duck from duck chess. if the little kid is captured, he screams capturing every piece on the side that captured the kid.

the cursed sword. the cursed sword can move like a rook but can pierce through 2 pieces capturing both. cannot capture a 3rd but it can capture the piece where it stops. if the cursed sword captures more that 4 pieces it will become enraged and can pierce through 5 pieces instead of 2 also when enrages moves like a queen. (extra info. value: 10 points. way to get the piece: have the rook capture another rook.) btw if the king is on the same file in front of 1 piece or 5 if enraged it is in check therefore must move.
The wall of bricks. Basically just the duck in duck chess, but this piece is worse because it replaces your rooks and queens with walls of bricks.
