Bass from the Mega Man series

Here is the updated side characters list:

Victor Sullivan, Elena Fisher, Ellie, Clank, Daxter, Kazuhira Miller, Liquid Snake, Hal Emmerich (Otacon), Albert Wesker, Agent (Resident Evil 6), Roman Bellic, Garrus Vakarian, Mordin Solus, Thane Krios and Mona Sax.

I think I can come up with more later.

I don't know many of these characters being recommended so I might need some help. I'll put them in anyway if they're requested.

Doing another post so you have a better chance at seeing it:

Chip (Sonic Unleashed)

David (The Last of Us)

Groose (Zelda)
