Chuck Chambers (Ryan Ochoa) is the secondary antagonist of the show but only (so far) towards Spencer. He first made an appearance in "iHurt Lewbert", playing racquetball in the lobby, for which Spencer got him grounded by his father for two days. Since then, Chuck and Spencer became rivals and have clashed on several more occasions each time ending with Spencer winning and Chuck getting in trouble with his father except in "iFind Lewbert's Lost Love". He reappears in "iBeat the Heat", where he comes to the Shays' apartment with his dad and sister, Gia, who Spencer finds attractive. Chuck also appears in "iReunite with Missy" and "iTwins".
