I need some time for the graphics.
Let's invent some very weird pieces

The Time Traveler
The Time Traveler can do a normal move like a Queen, but he has no normal capture.
As a special function, the Time Traveler can do a postponed move, as if he were traveling two plies into the future. The procedure for this is as follows:
1. The player who's turn it is, announces that he or she wants to move the Time Traveler. But this move is not yet done.
2. The opponent does a move.
3. The player does a move with another piece.
4. The player now does the postponed move with the Time Traveler. The move must be done considering the position after step 3.
The Time Traveler can only capture while doing a Time Traveling move.
During step 2 and 3, the Time Traveler cannot be captured because he is assumed to be somewhere else in Space and Time. His starting square can get occupied or jumped over by another piece, and this is of no consequence for the Time Traveler.
After step 2, the opponent's King is not allowed to be in check even from the Time Traveler, who is then on his way back to the board.
After step 3, the friendly King can be in check, but only if after step 4 the Time Traveler gets his friendly King out of check.
Example of a Time Traveling move:
Now White announces a Time Traveling move:
Now Black moves a Knight:
Now White plays Bxb6:
Now white plays with the Time Traveler:
Example of mate in one: announcing to move the Time Traveler mates:
Anyways K+N+TTrv versus lone King is forced mate.

I have already changed that post a few times. But so far it feels quite logical. I think that during a test game we might encounter some difficulties in the rules.

I think I should make it allowed to combine scenario 1 with the other scenario's 2 and 3. Jump your own piece and ask a specific reply from your opponent, if agreed then finally your own piece must move out of the way. Perfectly logical.

Toliet (LOL) eats everything within 3 squares (Sucks in ) (but not diagonaly)
I would say Black Hole.

I am kind of figuring out if I could make the Time Traveler's rules more simple but then also more generic. It could have been put this way:
"Do a move m1, m1 is now not legal. But either m1 is made legal afterwards by an own move m3. Or m1 can be made legal afterwards by an opponent's reply m2. In both cases as if m1 itself had occurred afterwards instead of before."
Now m1 can be illegal for any reason:
- Moving away from a Zombie or Magician, and m2 must consist of moving that Zombie or Magician away
- A Cannon captures without an in-between piece, and m2 consists of putting a piece in-between
- Putting the own King in Check, and with m2 the King is not captured
- Jumping a piece and with m3 a Witch makes it possible afterwards
- Take a Dwarf and m3 puts a second attacker in place
- Take a piece made immune by the Angel, and with m2 the opponent moves away the Angel
The first version only takes into account jumping and capturing.

I have completely modified the original description of the Time Traveler. The rules are much simpler and the piece is now better playable.

That is the piece that I made called the "Bomb" it is part of a variant that I am currently working on called "Armageddon" chess.
Here is how the Bomb Functions:
- It moves like a Rook, but it can only move a maximum of six squares
- It captures like a Rook until it has been "activated"
- It can be captured normally until it has been "activated"
- You can "activate" the Bomb, which uses up a turn
- Once activated the Bomb cannot capture pieces
- If Captured after getting activated the piece that captures it has to exit the board, and the bomb has to take a timeout for three turns and returns to its starting position deactivated
- Once activated the bomb can move for 5 turns until it explodes and destroys itself and everything around it (friend or foe) other than pawns, the destroyed pieces exit the board for the entire game
- Pawns can't be destroyed,[If being used with pieces from other variants] transparent, guards, dwarf pieces can't be destroyed
- Can't be activated adjacent to the King (yours or enemy's)
It is a flexible piece and can be used in bulldog chess

can the suck in part costs 1 move?

For me, the challenge of this topic was to give every new piece an aspect which was at that moment nowhere to be found in previously invented pieces.
For example, when the Rook exists and the Knight exists, the Rook-Knight compound has the combination of existing things, but nothing new. Both the Rook and the Knight move and capture in a certain way, and it's nothing different with the compound of them.
But then when we invent a piece with some side-effect or some really other behaviour, we have a really new aspect. The Magician for example, who could freeze pieces. (So even the Zombie had no new aspect, the Magician was already there, only with a different movement and a different freezing range.)
(This is also why I disliked musketeerchesspieces being mentioned here: all totally normal FIDE chess pieces from this point of view.)
Now I believe that I am at the point where I no longer can think of new aspects. I speak for myself of course, please prove me wrong! But one side comment still, I only take into account playable pieces, which after a reasonable reading and playing time start feeling like natural chess pieces and keep a balanced game.
But I start to believe that we can no longer come up with something really new.

that means its time to make another variant by itself
Ohhhhhhh, that’s why you asked for the goat
I can moderate your game against auk
