It's a joke on how the Hazel II looks absolutely.nothing like the Hazel, and is instead basically a recoloured Woundwort.
That's because TR-6 Hazel II is probably only imitating the *shield booster part of the TR-1 Hazel II instead of the actual unit. The actual Hazel imitation would be more along the lines of Barzam II and whatever the version that used MP Owsla parts was called.

With the TR-6 "Woundwort" acting as the core, a wide variety of optional parts can be swapped in to deal with every possible imaginable situation.
This concept born out of the unified standardization plans allows a single machine to replace the roles of all currently existing Mobile Suits.
