After doing some research I found why Emma is able to Mind Control robots.

Tech Champs have class advantage over Emma so they can't be immune to Mind Control.
This makes zero sense.
Tech champs have Class advantage over Omega Red but his Death Spores stack slowly on them.
Medusa has class advantage over Tech but she is able to Armor shatter and reduce Robot's AAR.
Human Torch has class advantage over mystic but he still have special bonus against them.
Professor X will be soon in the game.
I just want to know if Robot champs will ever get mind control immunity?
