Lamar Odom and Shaquille O'Neal are back on Kobe Bryant's team ... in the celebrity attack on the Power Balance bracelet empire ... TMZ has learned.
TMZ has obtained court papers, which show Odom claims the company stiffed him out of $133,870 before it filed for bankruptcy back in November.
Lamar was a minority investor in the company ... and swore by the non-scientifically proven magical powers the hologram-embedded bracelet is said to possess.
As for Shaq -- a former Power Balance spokesperson -- court docs show the big man is demanding $308,170.
The two join a long list of athletes who claim PB needs to open up its checkbook ... including Kobe ($400,000), Blake Griffin ($20,000) and skateboarder Ryan Sheckler ($25,000).
TMZ broke the story ... PB was ordered to shell out $57 million in a class action lawsuit after a bunch of former PB wearers called BS on the company's claim that the bracelet could enhance balance, flexibility and strength.
