Season Eight

"By the way, next time, you might want to try microfiber, works wonders". Tess Mercer to Lois Lane, Odyssey.

Lois sees Tess for the first Time

Lois and Tess first met when Lois was sniffing around the Luthor Mansion for clues to the whereabouts of her cousin Chloe Sullivan. Disguised as a French maid, Lois tried to trick newcomer Tess into believing that she was a servant but Tess remained unconvinced. Lois at first presumed that Tess was one of Lex's secretaries, but then Tess revealed that she had heard of the intrepid Lois Lane and that she had been waiting to meet her. When Lois called into question the true intentions of Lex Luthor, Tess strongly defended her mentor, saying that Chloe probably deserved to be arrested.

Tess and Lois at The Daily Planet CEO office

When Lois discovered that her new boss at the Daily Planet was Tess, she was far from pleased and described Tess as a "pit-bull in Prada". Lois continued working for Tess, although their interactions were not entirely pleasant. Despite their ill-feeling towards each other, they shared one thing in common: Oliver Queen. Both used to date him and when he hit the headlines after collapsing during a charity event, Tess thought that it was caused by Oliver's addiction to alcohol. Whilst Tess wanted to berate him in the paper, Lois confronted Tess and insisted that Oliver was a good person. Tess revealed that she knew of the relationship that Lois had with Oliver and felt that she couldn't be objective enough to write the story. Lois decided not back down in front of Tess and accepted the job unknowing that Tess also had a past with Oliver.

Tess finds a super powered Lois

When Tess' Crystal of Knowledge was stolen, Tess suspected Lois and hired meteor freak, Sebastian Kane, to find out what she knew about the theft. Although Sebastian discovered that Lois knew nothing of the crystal, he also realized that she had discovered his criminal past. When he informed Tess that he would have to kill Lois, Tess was nonchalant and responded without remorse or guilt.

Tess obviously considered Lois to be expendable, although she quickly changed her mind when she encountered a super powered Lois, after she had been possessed by Faora. During this encounter, Tess discovered more information about the mysterious Kryptonian that she had earlier heard about from Maxima. This information intrigued Tess and, once Lois was exorcised of Faora, Tess gave Lois a raise, because she realized that having Lois close could answer many of the millions of questions that she had.

Lois fighting Tess

When Chloe disappeared after running away with Davis Bloome, Lois learned that Tess was tracking them and decided to get into her office to see what she could find out. With the help of Jimmy, Lois decrypted her computer and found a video in which Tess cruelly interrogated Regan Matthews about the orb. Tess learned that Lois was in her office and accused her of having stolen the orb.

As Lois was more interested in finding Chloe, she quickly resigned herself to losing her job following her break-in. However, Tess was not willing to leave it there and began to fight Lois in a desperate attempt to force her to reveal the location of the orb. Tess began to strangle Lois but she defended herself by hitting Tess in the face with a box that held the Legion ring. As Tess fell unconscious on the floor, Lois became intrigued by the ring and, as she picked it up, she was transported to another time.

"Well, I'm not gonna get into the whole "she said, she said" thing with you". Lois Lane to Tess Mercer, Metallo.

Lois confront Tess

After being missing for three weeks, Lois suddenly reappeared and thought that her memory loss was due to something that Tess did to her. She went to the Luthor Mansion to confront Tess about what had happened and to let her know that she would not leave her job, but Tess told her that she had nothing to do with her disappearance. Tess told her that she had already fired her and then Lois threatened her saying that she would reveal to the world what she had heard in Regan's interrogation video about an alien invasion. Tess decided to rehire Lois, especially as she wanted to find out where she had been. Tess decided to keep track of Lois by installing spy-wares on to her computer.

However, when Tess woke up transformed into a monster, Lois was made to back her words and decided to write an article about it.

Tess synchronize her mind with Lois

Tess continued to monitor closely Lois, controlling their therapy sessions and all their movements, until Lois fell into a coma after suffering a breakdown. It was then that Tess found the perfect time to discover the things locked inside the mind of Lois and kidnapped and moved her to Belle Reve to subject Lois to special treatment. Upon discovering that Lois had been in the future, Tess decided to connect her mind to Lois mind to understand fully what she had seen. After witnessing the possible future, Tess ordered her assistant erase all the memories that Lois had, even when that meant leaving her in a permanent coma but was stopped by Clark Kent.

Tess was suspicious of Lois when she received a parcel at work. Lois had to reveal proof that it was for her before Tess would leave her alone. Little did they know that they would both become Checkmate agents.

Lois was more than happy to gather information about Tess for the Blur, although this was actually Major Zod disguised as the Blur. Lois discovered John Corben was in Tess's lab and was being experimented on and with that she helped him find kryptonite to recharge his weakened heart and tried to get him out of Metropolis, but they were intercepted by one of Tess' agents.
