Definitely Namor. You can use other champ to deal Biohazard node. But Namor is the only champ that can deal Electro's passive damage when struck, same goes to Korg, and most importantly in Variant 3. Dude is amazing
as long as there is no immunity this man is beyond god tier
Omega Red. AA can stop regen, Omega can outdamage it, plus immunities, regen, etc. Loooots of champs can handle regen and evaders aren't that big of a deal anymore for the most part. Omega is the 6.1 Crossbones master.Also, don't eve let the number of sig stones you have dictate what champs to rank as some say. AA really gets his utility at 1. Omega gets better with sig, but is still good at 20. You will eventually get more stones and level his sig up.
