Caveira (Rainbow Six Siege), a fictional Brazilian special operator in Tom Clancy's Rainbow Six Siege.

Caveira's Silent Step ability allows her to dampen her footsteps greatly, making her an effective stealthy roamer. Silent Step can be activated for a few seconds at a time and functions on a cooldown. The ability doesn't completely negate sound, but she becomes much harder to notice among other sound pollution.

The Mega-Sena is the largest lottery in Brazil, organised by the Caixa Econmica Federal bank since March 1996.
