8 has the ability to pilot any mobile suit it comes upon. It argues with Lowe about how to upgrade mobile suits and often engage in friendly banter with him. Usually, 8 helps Lowe out during combat by giving suggestions on what decisions are best for him. 8 also warns him when he has a chance of dying. It communicates with people through the words displayed on its screen, and can express its feelings or mood by varying the way the words are shown.
- In the promotional video for Gundam Seed Astray, 8 is given a voice but this contradicts what is depicted in many stories and may have been an oversight.
