Bakugan
Darkus Gargulion :: 1000G Darkus Specter Gargulion :: 1200GRecordKill Count
For someone of Markus' background, killing people would be the last thing anyone would see him doing. This unforeseen tendency of his to do so when Roxy was killed earned him the second highest kill count of the Resistors, second only to Noland.
Dryoid: Turned to stone by Gargulion, and then crumbled into pieces
Dark Angels: Redirected their combined attack onto the DNA barrier MAC Spider put up, which - when broken through - disintegrated both of their Bakugan
MAC Spider: Terminated with extreme prejudice by Gargulion's Piercing Delete
Diablo: Brutally killed when Gargulion forced another Gargulion to grow inside of its body
Skystar: Brutally killed when Gargulion forced another Gargulion to grow inside of her body
Eden's Department B2: Assassinated by Markus and Gargulion using Infiltration Spirit
Leon Klein: Assassinated by Markus and Gargulion using Infiltration Spirit
Ryan Reyes: Assassinated by Markus and Gargulion using Infiltration Spirit
Hurranian Operatives: Killed when Gargulion manipulated Drago into collapsing the building they were in
Dasia Turano (2nd Death): Obliterated by the eruption of the Kilauea volcano, which Gargulion caused through Drago's body
Lydia Andersen: Gargulion extracted her soul from her body for battle application, leaving her body as an empty shell
Assists
Baalenoid: Markus fights him alongside the other Resistors until Drago finishes him off with Novia Driver.
The Pack: As a result of the fight with Baalenoid ending with their victory, the Pack were killed along with Baalenoid.
Dasia Turano (1st Death): Markus defeats her, injuring her greatly. Andrew finishes her off by glassing the entire city.
Trivia-While sharing personality traits with Tank, his on-screen appearances in battle haven't been nearly as stellar as his rival's despite being considered equal in power to him.
> His character design, which is a pun on Robert Griffin III of the Washington Redskins, greatly contributes to his amount of losses as it is meant to teach a valuable lesson where remaining stagnant in your ability to improve and having the wrong attitude in battle will not get you anywhere. He becomes aware of this in his battle with Noland at the state championship and begins to improve himself from that point forward as seen in his brawls at nationals.
> This stumbling block earned him the title for having the most losses out of any character in the series thus far.
-Currently, Markus is the first and only character to be personally defeated by Seiki's attack.
