Yes - Wally was the only one of the Teen Titans who didn't have a new name in their late teens. Dick became Nightwing, Roy Arsenal, Garth Tempest, Donna Troia. All except eventually Garth filled in their mentor's "family name" (Roy sort of, as Red Arrow).

Wally was just Kid Flash and then Flash, and he succeeded his mentor years before all the others did. As for the other speedster names: Fast Forward, Mercury, Dervish, Trajectory, Quicksilver, PDQ, Windsprint. That's just the unisex names, I'm obviously ignoring Speed Queen.

But here's a really, really lame suggestion: Flashback.
