Music critic Hagamenon Brito considered him one of the three greatest Brazilian pop rock bassists of all time alongside Paulo Roberto Diniz "PJ" Júnior of Jota Quest and Alexandre Dengue of Nação Zumbi,[2] and Emir Ruivo of webzine El Hombre compared him to Red Hot Chili Peppers' Flea.
[3] Shortly after his death in 2013, caused by a self-inflicted gunshot wound following increasing bouts of anxiety and depression,[4] he was featured in entertainment website Punk Brega's list of the Top 10 Greatest Brazilian Rock Bassists of All Time, in 10th place.
[23] Champignon's final project was A Banca, a tribute act/"spiritual successor" to Charlie Brown Jr. comprising former members Bruno Graveto, Thiago Castanho and Marcão, as well as new addition Helena "Lena" Papini.
[25] A Banca was, however, overshadowed by controversy; a parcel of Charlie Brown Jr. fans criticized Champignon for "not respecting Chorão's death" and "not mourning it properly", going to the point of dismissing him as a "cash-grabber", a "traitor" and a "Judas".
[27] In one of his final posts to his social media account he stated that the band's first full-length album was slated for an early 2014 release, following the end of their Chorão Eterno Tour in late August, but this never came to be.
[28] Towards the end of his life Champignon began to experience bouts of anxiety and sunk into a profound depression, disgruntled by criticism, his insecurities and financial problems caused by his hastiness.
[37] His wife, fellow musician Claudia Bossle Campos (whom he met in 2009 and married in 2012),[1] with whom he had a daughter, Maria Amélia (born 2014),[38][39] later stated that "everything would have been different if he and Chorão had truly forgiven each other".
