The switch : There are 4 of them for each player and you move one of your opponents every turn, it can only move next to one of yours, and if it captures, then the piece it captures goes to its location and becomes another switch controlled by the player whose piece was captured by the opponent's switch.
create the most stupid chess pieces!

The geometry dash cube: Whenever you make a move the cube jumps over the square in front of it and lands 2 squares ahead(like from a1 to a3). It gets captured whenever it touches either a piece or the other side, and the next turn it respawns one column to the right. There are 2 of them that start on a1 and h8. It can't capture, but can block check. If it is captured by a piece it respawns. If they try to respawn but the square is occupied than it will skip to the next column until the first square there is unoccupied.
A rook, but upgraded with powers of friction making. Whenever the rook moves across a board, it causes "damage" to the board from the subsequent square to the landing square, so that for the rest of the game, future moves by pieces which are not knights are limited to the first friction square on contact.

(Knights can jump over squares)
.
For example in chess 960, let's say a rook originates from e1, and midgame it moves to e4 followed by h4. This would mean that squares e2, e3, e4, f4, g4 and h4 have been affected by "friction", so
.
- if a bishop attempts to move from d1 to h5, it can only move from d1 to e2, since square e2 is "damaged"
.
- if the same bishop attempts to move from e2 to h5, it will get stuck on g4. since square f3 is not "damaged", but square g4 is
.
- if a queen attempts to move from a4 to g4, it will get stuck at e4, since squares b4, c4 and d4 are not "damaged", but square e4 is
.
- if the same queen moves from e4 to a8, it will move normally to a8, since squares d5, c6, b7 and a8 are not "damaged"
I think that may become more balanced if the rule would be applied on the knight(like a friction knight, that only affects the square it lands on). But balance is something this forum never heard of
Friction knight? So it just jumps but instead fall down because of the pressure and go one square more diagonal? Kind of like this?
