Uncollected Thanos 2 Strength
Thanos 2 in uncollected has an exceptionally unfair situation when he is low on health. If you are KO he starts the fight with 2 bars of health and likely a very nasty ability such as death touch. During this time he gains power to special 3 then will use it and KO you.
Thanos 1 has a similar problem but not quite as bad.
It seems almost easier to just start everything over and go from there. The revive heal up game consumes substantial resources.
I ended up using a special 3 defense and got lucky to finish him off after multiple tries. This just doesn’t seem balanced.
