Roserade are natural dancers, with elegant capes, agile legs, and six thorny, dangerous vines – three from the holes in each rose - with which to take many partners' hands. Even when dancing with fellow poison pokemon, these dances lead to numerous stab wounds; when paired with a human partner, it is one of the most elegant and beautiful ways to risk one's life.
A few Roserade trainers seek to bond with their pokemon in this manner, but they always do so with a spotter on hand within minutes of a hospital, if not a doctor themselves. Most often, the Roserade dance is a barbaric game of blood with an audience, where desperate men and women – in older times slaves, sometimes indebted, sometimes greedy for large sums of prize money – risk their lives to be the last of the six dancers standing. The Roserade attack the dancers freely from a distance while holding them with their vines, and if a trainer loses their grip, they must admit defeat; others hold on until they fall unconscious from Roserade venom. Those knocked out by the dance are typically taken to hospitals, but depending on how cruel-minded the person running the event can be, treatment is not guaranteed even today. And victory is no antidote; many who have thought winning the tournament would spare them, or whose doctors were not fast enough, soon succumbed to Roserade venom.
Interestingly, while Roserade are powerful in pokemon battles, it is extraordinarily rare for them to cause an accidental fatality. It appears that Roserade venom is most toxic to humans; a fact which many have held to reveal a disturbing truth about their trainers through the ages, yet which could alternatively be explained by self-defense from the old custom of hunting Roserade for their roses.
