Dr. Barcus is the top mind of Chronos. He created the Hyper Team 5 and other wonders for Chronos. However, he can't figure where he went wrong with Aptom. It's almost like he has no recollection of the mistake. is it possible one of Dr. Odagiris's people had something to do with Aptom's new found powers?

 

 

 

I think he just pushed his experiment too far, beyond even his own knowledge and suffered the consequences. Up until Aptom, they had never had a zoanoid like him developed.  Hence his lost number status. Even the best of genius can succumb to error... especially since we all know Dr. Balcus has a bit of an ego from living so long.
