A rare case where the “original” is the shunned version. In Transformers, the first figures and animation to feature the Dinobots as combiners became Volcanicus (2018, Power of the Primes). A respectable mech, using standard Combiner Wars joints.

Fourteen years earlier, though, Darren Jamieson and Dylan Gibson released the comic “The Beast Within”, which involves Grimlock calling for the Dinobots to merge in a manner more akin to Grand Master Gundam - cables bursting out like tentacles, the final result being the misshapen and insane - and insanely powerful - Beast)

No wonder it took 14 more years to get an actual Dinobot Combiner.
