Leo

Leo (originally named Lenard by the Corp) is a robot from the Max Einstein Books. He was created by the Corp's engineers for the purpose of being used to track down Max and "reclaim" her for the Corp. He is first introduced in Rebels With A Cause and appears in the following books.

Quotes by Lenard/Leo:
"There's no need for your friend to contact me, Maxine. Look! I'm already here." -Rebels With A Cause

"Hello. Greetings. Welcome." -Max Einstein Saves The Future

Leo and Lenard
Lenard and Leo both have an extremely human-like or humanoid appearance, to which Klaus says magnificent, but Max says creepy. They are also both very obedient to their masters, as robots are, but Leo was especially loyal to Max and fought with her in Saves the Future. Although Hana was the team leader, Leo still consented to Max's commands. Both Lenard and Leo have an iconic giggle that was passed on to them by Dr. Zacchaeus Zimm, Lenard's "father". Both robots have a reputation of TMI, too much information.

As Lenard
When Klaus stopped using the phone that Dr. Zimm had given him to track down Max, the Corp switched to another plan to locate the CMI. That plan was Lenard. Lenard was a humanoid programmed by Dr. Zimm and was plugged in with the information that the Corp knew. The Corp met Max in Ireland, where Max, Tisa, and Klaus were trying to help Siobhan's family during their crisis. Dr. Zimm had brought Lenard there, and gave Max sixty-seconds to make her decision, work for the Corp or witness the death of innocent bystanders. They barely escaped when Max decided to "treat" her "guests" to a drink. She got Redbreast from Mr. McGregor, an Irish whiskey, that was 115 proof and 57.5 percent alcohol.

Max commanded him to pour Dr. Zimm and his minions a glass, knowing that ingesting liquids was bad for Lenard's circuitry. Max also called back to the kitchen to light a candle and stick it in a meat pie. She pretended that it was Klaus's birthday. But Lenard wasn't fooled so easily. He knew that it wasn't Klaus's birthday, and it had already passed last month. To distract the thugs, Tisa aimed her improvised gear of carbon dioxide straight into the thugs' eyes. Max plucked a candle out of the birthday pie and tossed it into one of the whiskey glasses on Mr. McGregor's tray, singing Lenard.

As Leo
Leo was briefly mentioned in the conclusion of Rebels with a Cause. Ben recruited Leo for the CMI and described him as a good thinker and he knew how to work data like no one he ever met. Leo was actually Lenard, a goon for the Corp. Klaus reprogrammed him and erased the data that was put into him by Dr. Zimm and added a few extras like Albert Einstein quotes. But nevertheless, Leo still had the giggle that he had in his past life because of a small, erasable bug.

Saves the Future
Leo was first seen in Saves the Future as Max's assigned roommate, having his finger stuck in the outlet and being a very annoying and TMI roommate to Max. He was extremely loyal to Max, asking her about her preferences even though Hana was the team leader. He also fought alongside Max and protected her against the Corp. Max knew that Ms. Kaplan worked for the Corp, and that was why Ms. Kaplan stationed the group in West Virginia, the location of the Corp's headquarters, where Leo was born.
