If you activate Chimeric Mass’s last ability while it has no charge counters on it, it will become a 0/0 creature and be put into its owner’s graveyard as a state-based action.
Chimeric Mass
Activating the last ability while Chimeric Mass is a creature will override any effects that set its power and/or toughness to another number, but effects that modify power and/or toughness without directly setting them will still apply.
If the number of charge counters on Chimeric Mass changes while it is a creature, its power and toughness will change accordingly.
