The last wave of Legends class of Titans Return came with very nice surprises. A reissue of Generations cosmos (without Payload) and a repaint of Bumblebee as Roadburn (Chase).
Detail on these small figures isn't bad, there are enough paint apps that you wouldn't normally complain too much other than the usual unpainted hubcaps and rear end of vehicles.
Still, Toyhax came up with a single set that dolls up these 4 figures in one go.
Roadburn
As you can see in my pre labels pictures, I had Roadburn with the arms/forearms flipped configuration which works much better but means it cannot be transformed.
It allows for better posability and better looking arms, but the reprolabels set comes with improvements for the original configuration.
Car mode is quite alright, I painted the center part of the hubcaps with gray paint since I knew stickers were coming.
The car comes with enough front paint, but of course nothing on the back.
The reprolabels add quite a bit to the car mode, and only black stickers to the arms which help a great deal with definition which is a small problem in bot mode.
I went with the black stickers for the hubcaps and they look great! I just took a risk with it since I would normally go with the silver/traditional look but I am quite happy with how that ended up.
Not pictured, there's a couple of options for the internal cabin of the car mode that you'll see when you try to fit the titan master inside.
And of course, the back side of the car gets stop lights and more detail.
Cosmos
For me, the stickers in Cosmos felt a bit unnecessary.
They take the biggest chunk of the sticker sheet and are mostly to improve on the outside perimeter of the UFO mode.
What I do like about the set is the homage to the G1 stickers in the chest and the front insignia representation on UFO mode.
Most of the stickers are visible still in bot mode, with a couple of slight shiny accent on the shoulders and a nice set of alt stickers to re-apply an autobot insignia on the arms.
The rubsign homage in the front of UFO mode comes with an extra alternate sticker to apply on top that shows the red autobot insignia, I did it later and it looks great.
The perimeter on the UFO mode on the top is a very mild improvement, but maybe unnecessary for me.
The bottom black highlight is quite nice, it adds a level of depth to the alt mode, but there are still a few green on green sticker details that are welcome but pretty "meh" to me.
Seaspray
Seaspray is does have a decent amount of paint apps that left only little improvement for the stickers.
Boat mode seems quite alright, until you are brought to attention that the sides of the boat are unpainted just like most car modes have their side/back windows unpainted.
The stickers add very little in bot mode. I skipped the stickers that cover the belly logo because I like the original Autobot insignia that comes.
I did appreciate the stickers on the vents.
Boat mode gets the most love. It's just a set of stickers for both sides emulating more windows and a couple of anchor ingisnias.
The "pizza box gun" gets a front sticker that has an extra circle in the center to resemble a laser gun? Anyway it looks alright and there's a couple of options for it.
Brawn
I painted the hubcaps with dark gray and I think that was a great first improvement.
The bot mode is alright, I appreciate that blue bit near the waist and red insignia do pop nicely in the full yellow torso.
Car mode has a decent amount of pain. Of course as any recent car, the back of thecar is lacking windows and details, but for the amount of detail it doesn't feel too bad at all.
The stickers in bot mode add to the torso, I always feel a bit weird when putting a sticker over a piece of paint I appreciate, but the bit on top of the blue section has more and nicer detail.
The knee caps also get a couple of silver stickers that break from the full green look.
Car mode gets tiny details too. The front lights get a yellow sticker and the detail on top of the windshield gets the light details too.
Also the stickers to the side/back windows completing the look.
Conclusion
At the end, I'd say you can skip this set and use the money for another that will add more to the figures.
There are lots of options for each of the figures, but none of them make very visible improvements.
