chess-with-powerups

I've been working on a vibe-coded variant of the game of chess. Which game-breaking powerup should I add next?

• A bazooka that blows up pieces on the board~
• A jetpack that lets a piece travel to any square on the board~
• A Jedi robe that gives a piece the force, meaning it can Jedi-mind-trick other pieces into doing stuff~
• Scorpion's hook from Mortal Kombat, "Get over here!"~
• The Floor is Lava White/Black: turn all white/black (one or the other) squares into lava, removing all allied & enemy pieces on those squares at the end of your next turn.~
• Oops! All Knights: Upon collection, all of your non-pawn non-king pieces transform into knights.~
