Most pool powers

[Thunder Glove]

I had six pool powers on my namesake Brute: Boxing, Tough, Weave, Air Superiority, Flight, and Combat Jumping.

If memory serves, my Stone/Stone Tanker had five: Boxing, Tough, Weave, Teleport, and ... I forget now, one of the two other Teleport abilities that used to be a pre-requisite for taking Teleport.  (I never respec'd him after they changed the travel pools)

I was waiting for Gadgetry to respec my Bots/Storm Mastermind, but that never came to be.

You can't take 5 pools. You have Presence, Leadership, Flight, Teleportation, AND Medicine listed below...

I must have been remembering multiple respecs on the same MM toon.  I probably dropped the Flight pool and took Team TP and then Zone TP when it was available.  Maybe I had Challenge too.

Really couldn't remember I had to look up my Sentinel save to be sure but Nova had 10.

Air Superiority
Fly
Afterburner
Invisibility
Stealth
Aid Other
Aid Self
Resuscitate
Recall Friend
Teleport

He was almost exclusively ranged so that let me skip a lot of powers, and he had a lot of HammiOs like 30+ (Mostly Nucleolus and Centriole).
I was creating a new Set IO build for him when the news of the servers coming down hit. Never did get that second build done.
