Jabberwocky Chess

Among my most innovative chess variants developed recently.

Jabberwocky Chess

Jabberwocky is a fairy chess piece, represented on the chessboard by the King, moves and captures like a regular chess king, but at the end of each move it turns into a different type of chess piece, depending on the previous transformation, following the chain of transformation:
King > Pawn > Knight > Bishop > Rook > Queen > King

Thus, after moving a King, the King is transformed into a Pawn of the same color. After moving a Pawn, the Pawn becomes a Knight, and so on.

The game is played on an 8x8 chessboard.

At the beginning of the game, each player has 16 kings, located along the first two outer ranks of the chessboard, as shown in the figure below:

White makes the first move in the game.

As stated above, each piece's movement is accompanied by its transformation into another piece, following the cycle of transformations:
King > Pawn > Knight > Bishop > Rook > Queen > King
All chess pieces move and capture according to the FIDE Rules of Chess, except that Pawn moves only one square forward and King can be captured like any other piece.

When the King reaches the farthest rank from its original position (the eighth for White and the first for Black), instead of being transformed into a Pawn, it must be replaced, at the player's choice, by a Queen, Rook, Bishop or Knight of the same color, which is equivalent to promoting a pawn in standard chess.
The same is true for the King, who ended up on the farthest rank as a result of the Queen's transformation. Its subsequent movement along the farthest rank must be accompanied by its transformation into a queen, rook, bishop or knight, at the player's choice, but not into a pawn. It can only transform into a pawn by stepping onto the adjacent rank.

There is no castling in the game.
No stalemate, check or checkmate.
Capture is mandatory. If several pieces can be captured, the player chooses any of them.
At the end of his turn, a player must have at least one King of his color on the board. If this condition is not met, then such a player loses the game.
