Well i assume this is Thanos byhiself as opposed to with the Infinity Gauntlet, and judging by the picture it appears its DBZ fighter from lets say Saiyan Saga (Gohan looks like a little kid). I think DBZ team would like win.
Also which version of Thanos is it?
1. Current Version?
2. Earth 20051 version as seen in the picture? And if anyone's wondering its from Avengers and The Infinity Gauntlet 03.
3. Pre Bendis's version?
The only version that could win is the last one who's too durable to go down to energy attack at least at this stage of the DBZ saga and could take the team via telepathy.
