Unlike Useful Brother, he knows very little about Hubris, stating that he was "just some sap who got tricked into filling with mutagenic serum". However Muta does mention that he has gathered a following, telling Ophelia that all this and the poison experiments he had experienced must be in preparation of something.
Ophelia's Description Edit
I'd guess what we're looking at is the effect of that mutagenic goo we found in the muta-bear when applied to a human. It's...pretty terrifying!
Terrifyingly AWESOME. -ALAN
The patient has developed boils and is growing lots of horn and bone protrusions that look incredibly painful. Presumably the mutagenic goo is causing all this.
I'm all for saving the patient, but I kind of want to see where this mutation's going... -ALAN
I think we need to chop off and treat all these strange growths before treating the source so he doesn't mutate any further.
If you can heal a muta-bear, you can heal a muta-dude! Have faith! -ALAN
Use the chainsaw to remove the spikes, then use it again on the big mass stuck inside him. You'll know if you're doing it right if the mass starts to shrink, reducing to a small spike you must extract. Clean up any cuts, then you'll move onto his front. Clear the poison and boils with the syringe or slice and vacuum tactic. Proceeding inside of Muta, all there is to take care of are fires, poison, and spikes to extract. When you move on to the final region, there are even more fires, poison, and spikes, along with the mutagenic serum. Simply extract it with the tongs and fix everything else as same as before.
- Although it is not much, Muta Brother had an extra expression added to make him seem more fitting with his lines.
