The 32-year-old Barros, easily one of the most popular international sports figures to ever play here, hopes to re-display the talent and skills, plus the charm that endeared her to the millions of Filipino fans when she first played here in 1999.
Gametime is at 5 p.m. after the 3:30 p.m. opening rites.
Joining Barros in the forefront of Brazils campaign are setter Fernanda Venturini, Erica Coimbra and veteran Virna Dias.
After retiring and marrying Bernardo Rezende in 1999, the highly experienced Venturini, who last wore the green and yellow in the 1998 World Championship, is on a mission to teach the new players on the Brazil bench.
"My concern goes now to help the young players, give them my experience and composure," said Venturini.
Despite lacking a charmer like Barros in its line-up, Dominican Republic has an ample supply of talent ready to challenge the attacking skills of Brazils number eight.
The champions of the 14th Pan Am Games has a competitive squad composed of Yudelkys Bautista, Annerys Vargas, Milagros Cabral Dela Cruz, Kenia Moreta, Cosiris Rodriguez, Juana Gonzalez, Priscila Rivera, Alexandra Casso and Evelyn Carrera.
Bautista, the Pan Am Games MVP, is one of the most experienced hands in coach Jorge Garbeys rotation, having the most number of World Championship appearances.
Dela Cruz, another MVP material, will be in charge of keeping the Brazilian defense in their toes with her high leaping ability and powerful spikes.
