Mir-Cotael-Techil is a fellow andalite and good friend to Elfangor. He also was alive when the Andalite Dome Ship Crashed, and, sometime after the Animorphs saved Ax, he freed himself from rubble restraining him. The Dome Ship was starting to flood, and he was able to grab a fish in the water, (with lots of attempts, since this was obviously very hard to do) aquire it, and swim away. He later learned of the Animorphs, and helped them at times. He also has a morphing cube, and secretly uses this to recruit people to his own team of Animorphs.
