Musucas are not machines but large organic creatures, most likely created from various whale species through genetic modification. They serve as the Chimeran Army’s ‘main battle tanks’, but are seemingly outclassed by the Blue Fleet submarines in a one-to-one matchup (they appear to have problems dodging torpedoes).
Musucas attack via the use of sound/sonics from their noses. (Note: This is apparently an unproven fact in actual whales i.e. no evidence to suggest that whales are capable of using sound to stun their prey). Musucas can also be coated with a special bio-membrane fluid, giving it stealth capabilities and allowing it to carry smaller vessels (like Umigumos) and organic torpedoes.
One particular Musuca – Akahage (赤 ハゲ) or “Red Spot” appeared to differ from the other Musucas in several aspects. It is capable of sentient thought, independent functioning, and can speak the human language (perhaps telepathically).
