Inferno was a pretty damn
good reuse of a G1 name.

G1 Inferno got his name because he loved
extinguishing fires, BW Inferno because he loved
making fires! (and he's just a lovable character in his own right

)
"Burn in the fires of Inferno!"
To be fair, name reuses happened in G1 as well. We had two entirely unrelated Transformers who shared the same name such as:
+ Barrage (the Deluxe Insecticon rhino beetle)
+ Barrage (the Autobot lunar exploration vehicle fore)
- Lightspeed (the futuristic sports car Technobot)
- Lightspeed (the Ferrari F40 Autobot)
* Afterburner (the "Tron" bike Technobot)
* Afterburner (the Lockheed F-104G Starfighter Decepticon Skyscorcher)
etc.
So even keeping with just G1 itself, you do come across some name reuses amongst completely unrelated characters. It's almost as if Hasbro didn't think we'd notice!
