Companion Mashup

Ellie from The Last of Us

and Clementine from The Walking Dead

Unkillable sidekick characters from incredibly popular recent videogames is the theme, I suppose. 

Elizabeth is kinda the odd one out when it comes to zombies, I was thinking of putting in Alyx Vance instead but I thought I'd stay topical. 

Also interestingly: all three of them are playable in later installments of their respective series'.
