Marvel Contest of Champions characters - every signature ability

Every super hero in Kabam's beat 'em up Marvel Contest of Champions has a signature ability that massively buffs their stats, or neutralises certain enemies.

They're not easy to get: you need to combine multiple versions of the same hero to unlock, and then upgrade, these one-of-a-kind specials.

So, let's go through every ability for every character in Contest of Champions so you know which moves to go for.

As certain variables change depending on the ability's level, we'll mark those as "x%". And if you've got data on the characters we've missed, drop the details in the comments.
