Over the next few days, Mako, Bill, Leon, Erin, Iris, and Nathan were determined to prove themselves as a unified team. Each one of them focused on honing their individual skills and addressing the flaws that Commander Sable had pointed out.
The training area was very advanced and versatile as it could quickly create small rooms, build obstacle courses, create dummy bots to practice against, etc.
This was possible due to the whole room being built out of nanites that could reshape into anything and even repair broken things, making them quite handy.
Mako needed to address his recklessness and lack of discipline. Even before he ever awakened his powers, he always had the habit of running head-first into a situation without properly thinking it out.
Even though he was smart, and could think of creative and amazing solutions for the situations he finds himself, only if he gave himself the time to think things through.
