Ganke Lee is Miles Morales' best friend and is the first person that Miles confides his secret in. He helps Miles in understanding his new found abilities and even points out how similar they seem to Spider-Man's.
Ganke, Korean American, was the best friend of Miles Morales and the only person who Miles had shared his secret with. It was Ganke who figured out that Miles carried similar abilities to Spider-Man. He was first alerted to his friend's newfound powers when Miles came bursting into his room and explaining the events that transpired to give him such abilities. Thrilled at Miles's "cool" powers and making the initial assessment that he was a mutant, Ganke made suggestions that he should be a superhero and embrace his abilities; though Miles was much more reluctant to use his powers and wanted to ignore them in pursuit of a normal life. Ganke later made the correct deduction that Miles's abilities were not a product of mutant DNA, but as a result of tampered genetics.
Ganke served the purpose of covering for Miles as he later assumed his duties as the new Spider-Man and became his confidant. He received information about the obstacles Miles faced while he was Spider-Man, and tried to offer his input on how to deal with the situations he encountered. For instance, Ganke suggested that Miles battled his Uncle Aaron, the Prowler, instead of finding an alternate option; he believed that fighting him was the only way to put an end to the problem. Ganke later suggested Miles join up with the Ultimates, saying that they needed his assistance.
