Mega Piranha

the Mega Piranha is a common enemy found in the Ancient Abyss.

Description
The Mega Piranha is a serrasalmid characin fish that was presumably extinct. It did, however, survive in the deep, mysterious environment of the Ancient Abyss, inside the depths of The Living Infinite. Notably, it has also grown to immense sizes and gained a red coloration in its ventral area, as well as developed hugely modified fins.

Behavior
When they spot the submarine, they will chase it with ferocity and quickly bite it, being able to quickly damage the hull, which makes it a highly dangerous enemy. It should not be allowed to reach the submarine at all and must be killed as quickly as possible to prevent heavy hull damage or even death.
