Hmm, well, I would say Bernard (Bernie) for Gumball and Phoebos or Phoibos for Flame Prince. Both of these are just guesses.

Gumballs name might be Dougie ( find the reference ) and Flame Prince might be Perry

I like Prince Brad Gumball

I like Ronald and Phoebus.

@Chase McFly I agree with Phoebus for Flame Prince. In Greek Phoebus means "shining one." Little fact

I know y'all don't care but still

I'm thinking Prince Gumball's first name is Boris, and Flame Prince may be Phoebus.

Pheebo, like ths F.R.I.E.N.D.S sitcom

LOL I have never thought of this question. But yes, I'd imagine FP would be Phoebus. PG, I have no idea.
