What would happen if Thanos fought without gauntlet

my suggestion: Die most likely cuz with his gauntlet he's a huge madman but without it he's only good in strength so he'll die

Thanos would be in prison already

mantis would calm him and he would be carried to the prison

he is still powerfull without it

yep

you saw he standed up to iron man fat thor and caprin america the worthy

Thor's fat?
