The utterance of the word by Professor Uriel sent a vibration of enthusiasm and interest through the walls of the class.
Or maybe it was Jethro and his own excitement.
He already knew all there was to know about evolution. In fact, he knew even more than most. More than all.
However, his liking for this teacher gave him a sliver of a hope that Uriel might harbor a different perspective of what it meant or required for a mechbeast to evolve. Something beyond the common knowledge.
"We all know why evolution occurs. What triggers it," Professor Uriel began, his voice thrumming in the expectant silence.
"It's a rare trait found in some mechbeasts that have a high resonance with aether. Undeniably, few of you here will witness your mechbeast evolve because they presently have this trait. It will most likely happen at the Apex Stage, and if you are exceptionally fortunate, perhaps earlier."
