While their semblances are similar, they are used differently. Blake uses her semblance as a misdirect, allowing the clone to take the hit and not her (which is why it looks exactly like her), she uses it defensively. Sun uses his semblance offensively, using them to augment his attacks (and use them for specific actions), and doesn't expect the enemy to be fooled by them (which is why they look different to him).

As for the Metroid Grimm, it seems to be a Lieutenant Grimm. I wonder if it can talk. If a huntsman finds it:

Ren: What the-

Nora: -Hell is that?

Metroid!Grimm: '''Human  Juvenile  Occupation   Huntsmen   threat level   problematic    heavy support required    dispose of them. '''(Retreats as Alpha Grimm of all types converge).
