New opening screen question

Do the champs in the opening screen have anything in common?
America Chavez, Stark Spidey, Iron Man (Classic), Jessica Jones (sort of new champ), Mantis (new champ), Quicksilver (fan vote), Valkarie and Omega Sentinel.
Was just curious whether or not these particular champs were chosen for a reason or whether they were just randomly selected.

They probably just wanted to include more champs bcoz it's the Anniversary month

Ironman & Stark are the popular ones
Mantis & Jessica are characters of the month
Chavez covers LGBT & the Latin American segment
Valkyrie might be there to represent LGBT & black people
Omega may be bcoz she is technically Asian & also probably bcoz she looks cool
QS may be bcoz of tha fan vote...he looks cool as well

Game recieves more promotion in anniversary & big event months
They probably thought newer players will be more attracted/hooked if they see these characters after starting the game for the first time

I thought it was Old and New to highlight 8 years of the Contest.

New/Modern champs (Mantis, Quicksilver, Omega Sentinel, and Valkyrie)
Old/Classic champs (Jessica Jones since she's added fairly early but not as a playable character, Iron Man OG, Starky)... but then there's Chavez so I don't know. Lol.

At a glance I see America (left hand side) Vs the rest of the world/universe/multiverse.
