Overflow

Overflow (Romaji: Oーbaーfuroー, Kanji: オーバーフロー) is a maneuver developed by the Cyclops of Ophthalmos.

It's considered to be a state-of-the-art maneuver. As a result, most female cyclops wouldn't bother to teach it to a male. Because most female cyclops believe that males are inherently too stupid to learn such a complex maneuver.

Mechanics
Overflow begins when one flexes a muscle in order to produce a shockwave that'll travel throughout the body as a vibration. If the flex was performed as it should have been, then the vibration will travel straight to the muscle of one's choice.

Once the vibration is within the muscle one would like it to be in, one can utilize that muscle in order to maneuver with the force of both the muscle from which the vibration was flexed from and the muscle that the vibration is in at the moment. In other words, it the strength of one muscle will Overflow into another.

Advantages
Overflow can be used to augment the strength of one muscle with the strength of another. This allows one to maneuver with literally all of the strength within one's body if one so choses.

Cyclops uses it as an alternative to utilizing the full potential of their muscles. Instead of unlocking one muscle's full power, they emulate the result of that by using power from multiple muscles.

Disadvantage
The use of Overflow is dangerous to non-Cyclops. The muscles of Cyclops are capable of withstanding a lot more strain than the muscles of non-Cyclops. Because the muscles of Cyclops are never actually using their full potential unless they've been unlocked. So the augmentation that is induced by the use of Overflow doesn't tend to overwhelm their muscles.

This is different for other species. Their muscles have no such limiter. So their Overflows are actually a lot more powerful than the Overflows of Cyclops. But at the same time it's more damaging to their body as well. Non-cyclops user must take care no to overwhelm themselves.
