Tiger/Leo and Dragon/Leo meet at a strong 80-85%, two born monarchs who would each vote themselves ruler of the world. Tiger/Leo is so wonderful it risks royal isolation; Dragon/Leo is the indomitable king who stretches its claim too far. Put two crowns in one room and the sparks are guaranteed.
The attraction is immediate and grand, two charismatic Leos who recognize their own wattage in each other. Tiger/Leo brags about its conquests and Dragon/Leo demands loyalty without seeming to, so the romance is dazzling and a little competitive from the first night.
Both talk like leaders and neither likes to defer. Tiger/Leo boasts, Dragon/Leo commands, and the conversation can turn into a duel over who holds the floor. A little false modesty from either would go a long way.
When Tiger/Leo goes barreling in and Dragon/Leo refuses to be crossed, two prides collide and neither backs down. Each reads the other's confidence as a challenge to its own throne, which is a fast route to a stalemate.
Tiger/Leo can learn from Dragon/Leo that raw might needs a little charm-school polish. Dragon/Leo can learn from Tiger/Leo how to wear the crown a bit more lightly. Two rulers can share a kingdom if they agree to split it.
At 80-85%, a strong but combustible match of two Leos. Tiger/Leo and Dragon/Leo make a magnetic pair, provided each retires enough ego to let the other reign beside it.
