|Killed by zombies|
|Desperation to Overrun|
–Maddison Collins telling her friends at how she was unable to act when confronted by the undead.
Maddison Collins is a recurring character and survivor in The Last Ones.
Maddison is seen surviving from the zombie's by taking refuge in a penthouse belonging to Victoria Franklin and her father, the latter of whom is missing. Also present with Maddison and Victoria are Alexis, Angie and Jack. It's assumed that they got there sometime after the outbreak happened.
Maddison is first seen returning to the penthouse alongside Angie after an unsuccessful supply run. Maddison reveals to Alexis, Jack and Victoria that they ran into a group of zombies and that she was unable to take them out, thus leaving Angie to do so. The group then briefly debate whether to stay in the penthouse or try their luck out on the road.
At some point during the evening, the group are taken hostage by Eli Loche. Jack begs Eli not to hurt them and tries to insist that they're good people. Eli makes it clear he won't hurt them and remarks that harming them would be the last thing he would want to do, which Alexis scoffs at. A terrified Victoria cradles herself by Jack's feet and the two of them and Maddison sit fearfully and do nothing as Angie tries to escape and as Alexis makes a vain attempt at attacking Eli. Maddison is then placed in the master bedroom alongside Angie, Jack and Victoria.
The following day, Maddison and the others overhear a conversation between Donald and Amar, two of Eli's men, where it becomes apparent that Donald has sympathy for the prisoners. Alexis remarks to the others that he is their ticket to escaping. Later on, Eli announces to the prisoners that he is leaving the penthouse for a few hours. When Alexis insults him, he violently attacks her as Maddison watches on in horror.
Shortly after, Angie manages to convince Donald to help them escape. The group and Donald make their way downstairs, only to be stopped by an armed Sid. The hostages are once again locked up and Donald is later murdered.
The next day, Terry throws Donald's decapitated head into the room as a message from Eli after the escape attempt, much to the horror of the prisoners. It does, however, inspire the group to make a break-out attempt as a few hours later they make a lot noise to summon Sid into the room. Angie knocks him out and then she and Alexis go downstairs to confront Eli while Maddison remains behind with Victoria and Jack.
Sometime after Alexis and Angie go to confront Eli, Alexis returns and tells Jack to fetch Maddison and Victoria as they need to leave as zombies have entered the building. Maddison rushes downstairs with her friends and sees Angie alongside her younger brother Bobby and two of his allies Javier and Peter. The groups merge and meet up with Sean, Aimi, Shiro and Charlotte, some of Peter's friends, who are fighting off a horde of zombies. The group plan to escape through the back exit but Maddison is bitten in the shoulder and killed by the undead before they can attempt to do so. The group are left with no choice but to leave her behind as she is mauled.
This list shows the known victims that Maddison has killed:
- Possibly numerous counts of zombies.
- Maddison appeared in four episodes.
- She is the quietest and quite possibly the dumbest of the Penthouse survivors.
- Out of all the main characters Maddison only met Angie, Alexis, Victoria, Eli and Bobby properly, but she did briefly meet Peter, Javier, Sean, Charlotte, Aimi and Shiro before her death.
- Maddison is shown to be easily persuaded or at least somewhat disloyal, as she came around to Alexis's suggestion of keeping an eye on Angie, even though Angie had just saved Maddison's life just moments before.
