Sentinel is a computer program with a British accent who once replaced Maxum Brain when he lied to Eric when he said Vana was Maxum Man's first choice as sidekick, only for him to be shut down by a power-crazy Vana, causing the security systems to go offline. It can be said by the replacement of Maxum Brain that Sentinel is more advanced than him, even Eric is amazed at him.
