Madoka Aikawa (相川 まどか, Aikawa Madoka) is a support character in Metal Slug. She functions exactly like her sister, Rumi Aikawa, and replaces her in some levels. She also looks exactly like Rumi, only with orange hair and a grey backpack, pair of shorts and boots.
Madoka first saw the Regular Army's facilities as a mere patient, because her younger sister, Rumi, interned both her and her mother to the hospital due to her having a severe weakness in her legs that could have rendered her crippled permanently, and due to her mother having heart failure.
As soon as she started feeling better, she decided to inscribe into the Regular Army and work as a supplier like her sister. But what was going to be a simple transfer to another base as her first mission, ended up with her suffering the same paperwork mistake as her sister and being transferred to the heat of battle.
She now goes to the front as a battle supplier and medic to serve the friendly troops, but somehow she ends with only minor injuries, and because she walks endlessly trying to remember where she came from, many soldiers see her as another Wandering Ghost.
- Madoka's card in Metal Slug Advance indicates that she and Rumi are twins. This is false. Madoka is 11 years older than Rumi.
- The newest app icon for Metal Slug Defense shows her handling and firing a bazooka. This may speculate that she knows how to use one.
