I don't tank is a good choice for hive infiltration.

Spoiler for MLA:

The BETA was curious about Sumika who was the only one who could communicate with them. They never saw humanity as a threat and continued to research humans, until the day Takeru and the others finally destroyed the er, I don't actually remember the name but it's a huge hive anyway, and The Superior finally decided that they want to destroy humanity (and grab Sumika? It's been quite a long while since I've read MLA). And they did it with a single attack...

EDIT: I forgot to mention, the only sentient BETA is the Superior.
