Why was Kou too heavy for Moka at age 11?


Moka was always cited as being stronger than Kokoa who easily lifts the
Transformer Bat Kou despite weighing 200 lbs. In one of the _Capu2_ chapters,
OUTER Moka is turned into a kid and swings Kou around easily. But in a
flashback of Moka's eleventh birthday, Moka can’t lift Kou and indirectly
tells Kokoa she’s stronger than her. What?

Actually, Moka's strength tends to fluctuate at different points also.
