Can't Thanos just use reality gem to turn omnitrix useless? He did it multiple times with other weapons.

Lol Ben casually solos Thanos especially with his “alien morphing“ time reduced in his later feats.

Thanks wins due to the current state of the Ben 10 series being so terrible.

depends who draws first.

either ben chooses the right alien or the omitrix turns into bubbles. thanos can use the reality or time gem to force ben in and out of his transformations. ben has to pick alien x right away or he looses.

edit: never mind, didnt see thanos has the soul stone. with universal knowledge on ben he will definatly reality gem the omnitrix into bubbles.

Ben slaps him. Thanos was struggling against a group consisting of Spiderman, Strange, Ironman and fodder

Thanos himself was fodder

thanos kills him before he can do anything

There are Ben 10 fans that would argue he beats comic book Thanos. MCU Thanos has no chance.

Ben.
