Lyra

Lyra is an EM Being from Planet FM. She has the power to EM Wave Change with Sonia Strumm to become Harp Note. Lyra is not only Sonia's partner in combat, but also helps Sonia write songs, and sometimes plays the role of a parental figure for Sonia.

Lyra tends to make flirtatious comments towards Omega-Xis after they become allies, which generally annoys Omega-Xis. Whether this is out of a genuine attraction or just another way to bother him is debatable.

MegaMan Star Force
Lyra is first encountered in MegaMan Star Force after the player defeats Cygnus Wing. She is shown to be arguing with Omega-Xis after he obtains the Andromeda Key, later taken from him by Taurus Fire.

MegaMan Star Force 2
Lyra continues as Sonia's partner, and stays with her even while the two appear to be teamed with Dr. Vega, helping Sonia with the facade. The two later return to help Geo and Omega-Xis.

MegaMan Star Force 3
Lyra and Sonia are given a much lesser role in the plot of MegaMan Star Force 3. They are still partners, both in fighting and in music, but are not seen as often nor play as large of a role as they used to. Sonia and Lyra help defend National WAZA Headquarters during the Dealers' attack, aiding them in holding off until Geo and Omega-Xis arrive.

Name
Lyra is named after the constellation Lyra. It was one of the first 48 constellations listed by the first-century astronomer Ptolemy, and is one of the 88 officially-recognized constellations in modern times.

Though it is a small constellation, the prinicpal star comprising it is Vega, which is one of the brightest in the sky. It is also bordered by the dragon Draco, the Greek hero Hercules, the little fox Vulpecula and Cygnus the swan.
