Note that the large Shogi variants also have pieces with 'linear' lion-like moves. Once starting in a certain direction they can either continue in tat direction, or reverse, but nothing else. This 'lionizes' a single move, rather than an entire piece. In Chu Shogi the Horned Falcon and Soaring Eagle have such moves. In Dai Dai, Maka Dai Dai and Tai Shogi there is a piece called Lion Dog, which (depending on the interpretation one gives to historic sources) can even do a triple linear lion-like steps in all 8 main directions. (The moves are not allowed to overshoot the starting square.) There also exists a piece (Free Eagle = promoted Queen in Tenjiku Shogi?) that (again depending on interpretation) is a lionized Ferz (in addition to having Queen moves). In a sense the Lion is a 'bent' version of the simpler linear double-movers.

This is a Lion restricted to moves comprising Coppergeneral steps. It can Igui capture only pieces otrhogall;y in front of or behind it.

This is a Lion restricted to moves comprising Tilegeneral steps. It cannot Igui capture as none of the one-step moves are retractable.
I understood that the Liondog of the larger Shogi variants was simply a Rook limited to moves of up to three steps and could not, for example, capture a piece and continue th moev afterwards. Thgis is certainly the impression that the Tai Shogi page gives. Is this not correct?
By the way, is anyone else having trouble reading the backslashes in the movement diagram? They look fine in the preview, but I cannot see them in the final display of the comment.

Thgis is certainly the impression that the Tai Shogi page gives. Is this not correct? Well, for one it would not just move as a Rook but as a limited range Queen (Q3) according to the source you gave the link to. But this is controversial, and just one interpretation of the historic sources describing the game. The evidence against it is also remarked upon in the same source, in the section about the Teaching King: historic sources state that TK moves like Q or LD, which makes as much sense if LD = Q3 as when they would have said that it move like Q or K, or as Q or R, etc. See, for instance, the description of the Lion Dog in Maka-Dai-Dai Shogi in the English Wikipedia.
I like "Tilelioncub"! Maybe it can even be used in some kind of shogi variant; maybe the Tilegeneral can promote to Tilelioncub. Other similar thing can be done with some of the other kind of pieces too. Even if it doesn't move very far at first, opponent can captured, drop on promotion zone, and then it is promoted during next turn. Now, you can stop in a space other than captured piece's space (or capture two pieces at once), even though you cannot stay still, as you would be with normal lion pieces.
You could use this "lion moves" possibly with riders too, for example a "rook lion" might move like:
********* ..4***X.. ********* .3+2$**X. ********* ******1.. ++++5*++6 ...++*+..Where "$" is this piece, "X" is other your pieces, numbers is capturable opponent's pieces, "*" is vacant spaces it can land on if not capturing, "+" is vacant spaces it can land on only if capturing, and "." is otherwise.
Therefore, you can capture 2 and 3 (stopping on 3), or capture 5 and 6 (stopping on 6), or capture only 1, or 2, or 4, or 5.
But, another variant might be, if, capturing a piece you must end on a space with a distance closer to the captured piece's square then it started from (if you capture two, you have to do for both)? Then, it might be:
..++3++.. ..4***X.. ********* ...2$**X. ********* ******1.. ..++5*+.. ....+*+..
As it turns out, this diagram does not explain everything, however.

Lion
This piece's move can comprise either one King step or two, not necessarily in the same direction, with a choice of capturng or not capturing any piece on the intertnediate square.Lioncub
This is a Lion restricted to moves comprising forward steps only. This means that it cannot make any move returning to its starting square, including Igui capture. Nor can it capture on a square one rank ahead of its starting square and then move to anoter square on that rank.Superlioncub
This is a Lion restricted to moves comprising forward and sideways steps only. Unlike the ordinary Lioncub this piece can make moves returning to its starting square, but only via squares on the same rank. This means that it can Igui capture only pieces on its starting rank. Note also that it cannot move to squares on its starting rank after going to a square one rank in front.Goldlioncub
2 2 2 2 2 \|X|X|/ 2-3-3-3-2 \|X|X|/ 2-3-2-3-2 |\|/| . 2-1-2 . | . . 2 . .This is a Lion restricted to moves comprising Goldgeneral steps. It can Igui capture only orthogonally adjacent pieces. It can move to adjacent squares on its starting rank in two steps, but only if the forward step is the diagonal one and the backward step the orthogonal one, regardless of order.Silverlioncub
This is a Lion restricted to moves comprising Silvergeneral steps. It can Igui capture only diagonally adjacent pieces. It can move to adjacent squares on its starting rank in two steps, but only if the forward step is the orthogonal one and the backward step the diagonal one, regardless of order. It cannot move to squares on an adjoining rank in two steps, or to any part of its starting rank in one.Supersilverlioncub
This is a Siverlioncub that can also make sideways steps. It can Igui capture only pieces on a different file. It can move to adjacent squares on its starting rank in two steps, but only if the forward step is the orthogonal one and the backward step the diagonal one, regardless of order.Lionfiler
This is a Lion restricted to moves comprising steps that change file, although two steps can cancel out. Like the Supersilverlioncub it can Igui capture only pieces on a different file. It cannot move to squares on an adjoining file in two steps, or to any part of its starting file in one.Lionranker
This is a Lion restricted to moves comprising steps that change rank, although two steps can cancel out. It can Igui capture only pieces on a different rank. Like the Silverlioncub it cannot move to squares on an adjoining rank in two steps, or to any part of its starting rank in one.
