Look, We all know Basemax doesn't appeared in the next episode of Big Hero 6 The Series Season 3 in The MiSFiT,Return to Sycorax,A Fresh Sparkle,The Noodle Ploy,The Krei-Oke Night and The Mascot Upshot. Because Basemax is still active, Cause in this episode De-Based has been turned bad and evil. Look I know Basemax is not an evil intelligence. They wanna help Big Hero 6 to stop the bad guys. But look at the Basemax's face, Looks so sad. This is why I saw a Mighty Mega Man from Big Hero 6 Wikia and the message "Unless it's canonically implied they're never returning, they're still considered active." (Sniffs) (Sad tune) We're all gonna miss Basemax (Cries)

Basemax belongs to Disney
