Another mask-wearing hero arrives in San Fransokyo. Having no qualms about killing, this man appears to be more of an adversary than an ally to the city's six heroes.

"He realized he made a mistake the second the front doors to the Showcase Hall closed behind him and a piece of ceiling fell from above, blocking most of the way out. 'You made a mistake Tadashi.'

All their enemies had seemed to learn, very early on, that attacking the youngest, smallest member of Big Hero 6 would cause the others to panic and become either too distracted to fight back or super focused to try to keep Hiro safe.

Hiro decides to take Aunt Cass's car out for a spin to prove he can drive. Tadashi is not amused. Pre-movie

Hiro had always reverted to calling for his Nii-chan when he's overwhelmed. 4 times when Tadashi didn't answer the call, and the one time he did. Post-movie, teamfic, alive!Tadashi (Part 1 of the 'Here Comes After' universe)
