Mordin. Hands down

Probably Mordin. Even Javik was confused by his thoughts when reading him

Oh, yeah, EDI, too!

Maelon and Mordin considering they could or did cure a complex disease as the Genophage depending on continuity

EDI

I would say it depends

Prothean history: Liara or Javik

Otherwise: Legion, Mordin, and EDI

Military wise: I would say Garrus……that dude is one bad MOFO HAHA!

If we categorise:

Prothean: Javik, Liara

Otherwise: Mordin, EDI and Legion

Tech: EDI, Tali and Legion

Military (Guns): Garrus, Ashley and Miranda

Biotic: Jack (I mean she's a biotic Teacher)

Organic - Mordin, Liara, or Miranda

Synthetic - EDI

Mordin

It's got to be Miranda. She brought the dead back to life. Shepard got spaced. That's not something you survive. It's cold as hell in deep space and there's no oxygen. Even with all of Cerberus' fancy tech. Most people weren't optimistic about project Lazarus.
