Teletraan 15 ("Ichigo," a.k.a. Mobile Teletraan 15) is one of several humanoid computers developed by the Autobots to be "living" extensions of the Teletraan I computer and based on the artificial Earth satellite Nana. This particular unit is shy, bumbling, and incredibly luckless. She frequently gets into trouble and often needs saving by (and occasionally from) her fellow Autobots. Her fellow Teletraan unit Teletraan 10 is frustrated by her antics, but still steps up to help her in a scrape... after a perfunctory round of sarcasm. The two are very close friends, despite their differences.
