I am honestly enjoying playing the 'normal' person of the bunch... and, as others have already said, these aren't normal companions but playable characters that have been designed with personal quests and so that you can experience something new from their perspective when playing as them as your origin characters.
Also, playing with a group of 'superheroes/supervillains' is very common in tabletop rpgs in general, when those that sit around the table and the GM agree to entwine their crazy elaborare backstories into the narrative which is an approach that I enjoy.
By looking at the companions, I can almost imagine the type of player that would create them and I personally find that quite charming.
