Dragon/Leo and Dragon/Aquarius meet at 67–72%, the Dragon king with Lion might encounters the neophiliac Dragon who lives for imagined futures. Both halves are Dragons, no Chinese-axis tension. The Western halves are zodiac opposites. Throne meets future.
Chemistry is theatrical on the Lion's side and cerebral on the Aquarian's. Dragon/Leo brings indomitable willpower and Lion might; Dragon/Aquarius brings cerebral neophilia and the avant-garde appetite. The bedroom is grand and inventive. The risk: the Aquarian Dragon's cool detachment reads as insurrection to the Dragon king.
Conversation is regal on Dragon/Leo's side and layered on Dragon/Aquarius's. Dragon/Leo declares from the throne; Dragon/Aquarius dissects the throne. The risk: the Lion's monologue meets Aquarian dispassion, and the Dragon king reads dissection as treason.
Friction lives in the Leo/Aquarius opposite axis. Dragon/Leo wants subjects; Dragon/Aquarius wants cooperatives. When the Dragon king demands fealty, the Aquarian Dragon designs an alternative governance, quietly and on schedule.
Dragon/Leo learns from Dragon/Aquarius that the avant-garde is not insurrection, it is invention; Dragon/Aquarius learns from Dragon/Leo that grandeur, well-aimed, can move people. Both Dragons practice charm school on purpose.
At 67–72%, this is a moderately compatible, double-Dragon pairing. Dragon/Leo and Dragon/Aquarius can build something, both halves trade despotism and dispassion for partnership on purpose.
