If we take all the 13 Primes we’ve seen and handled. They have all tried very hard to be, reference, or at least homage, past depictions. To varying degrees of success and YMMV.
Prima: Takes elements from FFoD and tries to be an ancient warrior. Very utilitarian alt,ode since he is ‘The First Prime’
Vector: Is trying as hard as possible to be Cybertron Vector Prime, within the limitations of being a Jhiaxus retool. He’s not trying to reinvent the wheel.
Micronus: He’s Very inspired by Cyberverse, while also using Apex Armour. I don’t personally thinkk it quite succeeds in what it wants to do, but he is very much, the tiny one.
Onyx: They went all out for this guy it seems. Since he’s beast bot, Centaur and a dragon/griffon? Barring maybe a repaint down the line, he’s great.
The Fallen: Is primarily inspired by the Dreamwave design. A flaming demonic Prime with a big gun and things to stab you with.
Solus: Doesn’t have a lot prior looks to go on, so they had a lot to play around with to make the blacksmith. Barring qc and fiddliness, and being a deluxe, she looks good.
Alchemist: A short, stocky wall of a bartender who takes elements of Cyberverse. And the altmode is, other than Cyberverse showing he’s a ground vehicle, not so specific.
Star Optimus: Is Star Convoy.
Quintus: He’s a squid guy who turns into a squid ship. Any tentacular transformer is going to have problems.
Amalgamous: He’s the modular dude who can multi form into anything. The figure captures this pretty well.
Liege Maximo: Is aiming to be G2… to the EXTREEEME.
Nexus is now a singular bot, who can become a torso piece and combine with anybody who wants. Which is an option sure. But his previous depictions show him as the First combiner, working like ther combiners. Multiple independents bots or components, with their own personalities, that merge to make Nexus.
This new AOTP take just makes him a guy who can Jack the limbs of other hestalt and puppet them. Which, as a play pattern, is an option, but for the frame system means you either need doubles, or you can’t have one or more of your other combiners built if you want Nexus to be Nexus Prime combiner.
Unless Hasbro does have a way to (eventually) give a purely Nexus frame set and limb team. This is people are disappointed the Hasbros release of the First combiner is underwhelming. I don’t hate this Nexus, I just think it’s a letdown when you realise he’s Nexus Brutirion.
