Kinda doesn't make sense Imu teleported Mars back just to protect Mariejois. There is no danger in Mariejois right now and Mars just sitting like a tired grandpa
I think the way to sent them back home is by make them unconscious / almost unconscious.
Mars was shaken really hard by Nika's combined attack, the impact was really hard he got KOed by the impact although his body can regen the damage
Rest of Jobberosei almost got unconscious by Joyboy's haki, they are panting hard like Nanao Ise panting from Captain Commander's spiritual pressure.
