MhaXwell is not here to teach ventriloquism, as could be mistakenly thought when hearing about his arrival in Rim Country. While technically a "dummy," there is nothing dumb about this one. As high tech as they come, MhaXwell is classed as a SimMan, an amalgamation of Simulation Manikin. MhaXwell is a virtual patient here to teach emergency medical techniques to first responders and local health care students. Funded by the MHA Foundation, MhaXwell was given his name as an homage to the foundation, combined with his mission of promoting wellness.
The SimMan was created by Laerdal Manufacturing, initially as an anesthesiology and military training tool, and has evolved to become a bio-realistic simulator capable of speaking, gasping, and even saying "oops" when a student makes a mistake, among many, many other abilities.
