Substituting "Poro" for things like "Pro" or "Proto" (because this is how creative I am not):
Porofessional
Porofessor (Porofessor Oak)
Porotein
Porogress
Porogressive
Porotype
Poro Favor (in Spanish!)
Or you could try jacking something that sounds good from mythology. I'm sure the common ones are all taken, but you could check for some pretty cool obscure Greek names like:
Astraeus
Pallas
Alcyoneus
Eurymedon
Laestrygonian
Amechania
Eleos
Himeros
Atropos
Sophrosyne
Tisiphone
Rhadamanthys
Tartarus
Ocypete
Nereus
I got a little tired of scrolling through Wikipedia after that, but there are tons more. Maybe Google the ones you like to make sure they don't represent something you don't.
Hope this helps!
