I consider him strong based on performances in MK9 and MK11.

Even with him being one of the characters that has a large losing streak?

Despite the large losing streak, he has shown to be stronger based on additional enhancements that were done to him by both Kanos.

So, what Mortal Kombat characters do you personally believe he would beat?

Quan Chi, Shang Tsung, Geras, Baraka, Ermac, Reptile, Jarek, Kobra, Kira, Drahmin, Moloch, Motaro, Goro, Kintaro, Jacqui Briggs, and Sonya Blade.

Uh, the first 5? Could you explain them?

Sektor has no soul to steal and his weapons give him an edge. His cloaking device can give him an edge and his teleportation is more improved than when he was human. As a whole it depends on which Sektor we’re talking about.

All of them. Original, Alternate and Current.

Sektor only had lost the most in the Alternate Timeline. Lost to Scorpion and Cyrax in human form. While in Cybernetic Form, only Smoke, Cyber Sub-Zero, Nightwolf, Scorpion’s human form, Sub-Zero, and Johnny Cage had defeated him. But I know in the Current Timeline, female Sektor only lost twice and won nine times. Female Sektor defeated Smoke, Johnny Cage, Scorpion (Kuai Liang), and Kung Lao alongside Cyrax. She also had defeated Khaos variants of Quan Chi, Shang Tsung, Geras, Raiden, Baraka, Ermac, Reptile, Kitana, Mileena, and Johnny Cage. Honestly, her Kombat skills improved a lot in the Current Timeline, while Sektor was stronger of being fully cybernetic in the Original and Alternate Timelines.

Ok, then.
