zeemf's hydra shark form has five heads, all the same person. They're linked together in a mental network so that all the heads sync up with each other.

When he first showed it to me I (almost immediately) had an idea for how Kree would manage to get himself into trouble because of it. Silly Kree... :P

This was drawn during a hydra-themed oC session. If you're interested, there's also a scrappy sequence I drew illustrating how Kree got himself into this mess :P

In a nutshell: Kree made the mistake of swapping heads with one of Zee's hydra heads, and now he's accidentally synced up with them and thinks he's Zee as well.

Remember kids, don't be reckless with your use of shapeshifting! :V
