in this final saga he was even more powerfull than Dabura the demon who fought gohan(stated by Japanese collections),for that reason by an editorial option made by akira toriyama Tenshinhan wasn' t in the group of supreme kai and kibito when dabura eliminated the weaklings like Kibito and transformed in stone krilin and Piccolo.Dabura couldn' t eliminate tenshinhan and for that reason Tenshinhan didn' t come for the tournament. Tien also can do the kaioken x20 all this is from the dizenshuu these are two hardly know facts like him being an alien. so this fight would be a violent curbstomp http://tenshinhanpowerlevels.blogspot.com/2007/10/dragon-ball-z-encyclopedia-daizenshuu-7.html
Tien was able to hold his own with Cell Jrs who were stronger than super Vegeta. Frieza was no match for Trunks who was weaker than ssj vegeta (newly attained). Vegeta's arm was broken by android 18, who in turn was no match for 1st form cell. This can be said because Cell beat the stuffing out of android 17 who is equal to (if not a little stronger than) android 18. This Cell was equal to android 16. When Cell attained his 2nd form, a full power punch from android 16 in Cell's face did not even phase Cell, in fact Cell barely felt it. However, Tien was able to own 2nd form Cell and absolutely humiliate cell.
This all supports the obvious fact that Tien would own Frieza.
Okay soooo this proves nothing else but the fact that as already known by many Dragonball fans the Dragonball franchise is a simple power race nothing more. so ofcourse Tien would be stronger then Frieza 2-3 decades after Cell got defeated because during that time he trained non-stop so its natural to assume he`s already over the 1.250.000 (Frieza`s power level when Trunks killed him) by then. anyway Tiencha wins locked
