Its been previously suggested for a player designed sidekick pet.
It would be a simple purchase at the game store, and you could design your sidekick any way you want (quadrupeds may not be available at launch-but eventually you could get animal pets as well).
The sidekick would not engage in combat, not be target-able, and would follow you around.
Your kick could be anything, from a fledgling hero to a Lois Lane/Jimmy Olson, to a robot girlfriend.
The kick would be a toggle on/off power, and would come with a basic emote package.
Other idle time packages could be purchased to further enhance your new pet kick.
Reporter: Idle package: will interview your avatar during downtime.
Lover: Idle package: will gaze lovingly at your PC with hearts floating over their head
Boy Wonder idle package: will catch his fist with his hand and excitedly discuss crime with the PC, (word balloons will say things like, "Holey Cow, Cyclops. You sure taught the Bossy Bovine a thing or two!")
Wife Idle package: Holds a baby in one arm, flips pancakes in a pan in the other. Takes money from PC. Opens purse, give PC a breath mint. Irons uniform. Vacuums area around PC.
Mutant Mentor idle package. bald guy in a wheelchair gives PC a lecture.
Tannimm idle package. Beats PC with a red crowbar. Trips PC with crowbar. Laughs pointing at PC. basically abuses PC.
Sith Package: Bows (word balloon) "Yes, My Master"
